    OPINION
    Judge James B. Morse Jr. delivered the opinion of the Court, in which
    Presiding Judge Kenton D. Jones and Judge Diane M. Johnsen joined.
    M O R S E, Judge:
    ¶1           The Arizona Department of Revenue (the "Department")
    appeals from the tax court's entry of judgment in favor of Carter Oil
    Company, Inc. ("Carter Oil"). We hold that dyed diesel fuel used to power
    machinery involved in mining and processing operations is subject to the
    transaction privilege tax. Accordingly, we reverse the decision of the tax
    court and remand for entry of summary judgment in favor of the
    Department.
    FACTS AND PROCEDURAL BACKGROUND
    ¶2             This case involves the application of Arizona's transaction
    privilege tax to Carter Oil's sale of dyed diesel fuel1 to Hanson Aggregates
    Arizona, Inc. ("Hanson"). Hanson uses the dyed diesel to power dozers,
    loaders, haul trucks, and rock crushers in its gravel mining and processing
    operations in Arizona.2 In addition to providing the chemical energy that
    powers the machinery, dyed diesel also acts as a lubricant for the
    1      "Dyed diesel has no special properties that make it more suitable for
    use in [a specific context]; the dye merely identifies it as exempt from the
    federal excise tax." Ala. Dep't of Revenue v. CSX Transp., Inc., 
    135 S. Ct. 1136
    ,
    1149 (2015) (Thomas, J., dissenting). Thus, the only difference between
    dyed diesel and non-dyed diesel is that dyed diesel is dyed red, only legally
    permitted for use in certain off-road diesel vehicles and machinery, and
    exempt from state and federal fuel excise taxes. See A.R.S. §§ 28-5601(9), -
    5610; -5645; 
    26 U.S.C. § 4082
    (a).
    2      The parties agree that Hanson uses the dozers, loaders, and haul
    trucks in mining operations. The parties dispute whether the rock crusher
    is used in mining operations under A.R.S. § 42-5061(B)(2), but the
    Department concedes the crusher performs "processing" under A.R.S. § 42-
    5061(B)(1).
    2
    CARTER OIL v. ADOR
    Opinion of the Court
    components in the machinery's fuel systems. Without fuel, the machinery
    Hanson uses for mining and processing would not operate.
    ¶3            Carter Oil filed a refund claim for $11,769.45 in taxes it paid
    between January 2011 and June 2013 on the dyed diesel it sold to Hanson.
    Carter Oil asserted that the revenue from its sale of dyed diesel to Hanson
    was exempt from the transaction privilege tax under A.R.S. § 42-5061(B)(1)
    and (2) as "machinery or equipment" used in mining and processing
    operations.
    ¶4            The Department denied Carter Oil's refund claim. After
    exhausting its administrative remedies, Carter Oil filed a complaint in tax
    court pursuant to A.R.S. § 42-1254(C). The Department filed for summary
    judgment, and the tax court denied the motion, holding that the dyed diesel
    qualified as machinery or equipment when used directly in mining
    operations, and was therefore exempt from the transaction privilege tax.
    Ultimately, the tax court granted judgment in favor of Carter Oil. The
    Department timely appealed, and we have jurisdiction pursuant to A.R.S.
    § 12-2101(A)(1).
    DISCUSSION
    ¶5             We review the tax court's ruling on a motion for summary
    judgment and its interpretation of Arizona's tax statutes de novo. SolarCity
    Corp. v. Ariz. Dep't of Revenue, 
    243 Ariz. 477
    , 480, ¶ 8 (2018). Exemptions
    from the transaction privilege tax must be strictly construed, with "the
    presumption being against such exemption." Tucson Transit Auth., Inc. v.
    Nelson, 
    107 Ariz. 246
    , 252 (1971). Nonetheless, exemptions should "not be
    so strictly construed as to defeat or destroy the [legislative] intent and
    purpose." State ex rel. Ariz. Dep't of Revenue v. Capitol Castings, Inc., 
    207 Ariz. 445
    , 447-48, ¶ 10 (2004) (alteration in original) (quoting W.E. Shipley,
    Annotation, Items or Materials Exempt from Use Tax as Used in Manufacturing,
    Processing, or the Like, 
    30 A.L.R.2d 1439
    , 1442 (1953)). Applying these
    standards, we consider whether the dyed diesel at issue was exempt from
    the transaction privilege tax under A.R.S. § 42-5061(B)(1) and (2).
    A.      Exemptions from the Transaction Privilege Tax.
    ¶6             Arizona's transaction privilege tax is "an excise tax on the
    privilege or right to engage in an occupation or business in the State of
    Arizona." Ariz. Dep't of Revenue v. Mountain States Tel. and Tel. Co., 
    113 Ariz. 467
    , 468 (1976). The retail classification imposes a tax on the gross proceeds
    of sales or the gross income derived from the "business of selling tangible
    3
    CARTER OIL v. ADOR
    Opinion of the Court
    personal property at retail." A.R.S. § 42-5061(A). The parties agree that
    dyed diesel is tangible personal property.
    ¶7             The legislature carved out numerous exemptions to the retail
    transaction privilege tax. See A.R.S. § 42-5061. The exemptions at issue in
    this case are for:
    1. Machinery, or equipment, used directly in manufacturing,
    processing, fabricating, job printing, refining or metallurgical
    operations. The terms "manufacturing", "processing",
    "fabricating", "job printing", "refining" and "metallurgical" as
    used in this paragraph refer to and include those operations
    commonly understood within their ordinary meaning.
    2. Mining machinery, or equipment, used directly in the
    process of extracting ores or minerals from the earth for
    commercial purposes, including equipment required to
    prepare the materials for extraction and handling, loading or
    transporting such extracted material to the surface. "Mining"
    includes underground, surface and open pit operations for
    extracting ores and minerals.
    A.R.S. § 42-5061(B)(1) and (2) (the "mining and processing exemptions").3
    The issue we must decide is whether the dyed diesel sold to Hanson is
    "machinery or equipment" used directly in mining and processing
    operations.4
    3      The legislature provided similar exemptions to the use tax. See
    A.R.S. § 42-5159(B)(1) and (2). While the transaction privilege tax is
    imposed on revenue from sales within the state, the "use tax is designed to
    reach out-of-state sales of tangible personal property to Arizona
    purchasers." Ariz. Elec. Power Coop., Inc. v. Ariz. Dep't of Revenue, 
    242 Ariz. 85
    , 87, ¶ 7 (App. 2017); see A.R.S. § 42-5155(A). The two taxes are
    complementary. Ariz. Dep't of Revenue v. Care Computer Sys., Inc., 
    197 Ariz. 414
    , 419, ¶ 22 (App. 2000).
    4     Our analysis of the term "machinery or equipment" used in both
    subsections is the same. See Obregon v. Indus. Comm'n, 
    217 Ariz. 612
    , 616, ¶
    21 (App. 2008) ("It is a 'normal rule of statutory construction that identical
    words used in different parts of the same Act are intended to have the same
    meaning.'" (quoting Gustafson v. Alloyd Co., Inc., 
    513 U.S. 561
    , 570 (1995))).
    4
    CARTER OIL v. ADOR
    Opinion of the Court
    ¶8             "'Our primary goal in interpreting statutes is to effectuate the
    legislature's intent' as expressed in the statute's text." Silver v. Pueblo Del Sol
    Water Co., 
    244 Ariz. 553
    , 559, ¶ 22 (2018) (quoting Rasor v. Nw. Hosp., LLC,
    
    243 Ariz. 160
    , 164, ¶ 20 (2017)). If a statute is unambiguous, "we apply it
    without further analysis." Glazer v. State, 
    237 Ariz. 160
    , 163, ¶ 12 (2015).
    ¶9              When this Court first addressed the mining and processing
    exemptions we found that "the legislative purpose for the exemption statute
    is to encourage mining in this state so that the end product of that mining
    and metallurgical activity (sales of copper) is itself subject to taxation under
    the transaction privilege tax." Duval Sierrita Corp. v. Ariz. Dep't of Revenue,
    
    116 Ariz. 200
    , 204 (App. 1977). In Capitol Castings, our supreme court
    tracked this precedent and found that the exemptions lack "definitional
    specificity" but their underlying purpose is "to stimulate business
    investment in Arizona in order to improve the state's economy and increase
    revenue from other taxes, such as income and property taxes." 
    207 Ariz. at 448, ¶ 13
     (first citing Ariz. Dep't of Revenue v. Blue Line Distrib., Inc., 
    202 Ariz. 266
    , 268, ¶ 11 (App. 2002); then citing Duval Sierrita, 
    116 Ariz. at 204
    ); see
    also Mesa v. Smith Co., 
    169 Ariz. 42
    , 45 (App. 1991) (recognizing that we are
    "bound by the construction of a statute given by the Arizona Supreme
    Court."). Thus, "applying [a] more expansive definition of machinery or
    equipment better serves the legislative goal." Capitol Castings, 
    207 Ariz. at 451, ¶ 24
    ; see also Empire Sw. LLC v. Ariz. Dep't of Revenue, 
    244 Ariz. 542
    , 546,
    ¶ 21 (App. 2018) (review denied Oct. 30, 2018) (Beene, J., specially
    concurring) (explaining that Capitol Castings precludes us from applying
    "the 'primary rule' of statutory construction and giv[ing] the words in § 42-
    5061(B)(2) their ordinary meaning").
    B.      Capitol Castings Test for Determining Exemptions.
    ¶10           In Capitol Castings, our supreme court addressed the
    "machinery or equipment" exemptions and held that "silica sand, chemical
    binders, exothermic sleeves, mold cores, mold wash, and hot topping" are
    exempt from the transaction privilege tax when used directly in a
    "qualifying process." 
    207 Ariz. at 451, ¶ 26
    . In reaching this conclusion, the
    supreme court relied on Duval Sierrita, where we "adopted two tests—the
    ultimate function and integrated rule tests—for determining whether items
    were machinery or equipment 'used directly' in qualifying operations"
    under the mining and processing exemptions. Capitol Castings, 
    207 Ariz. at 448, 451, ¶¶ 15
    , 24-25 (citing Duval Sierrita, 
    116 Ariz. at 205-07
    ).
    ¶11          In Duval Sierrita, we held that spare and replacement parts, as
    well as a conveyor belt, pipes, and booster pumps, were exempt. Duval
    5
    CARTER OIL v. ADOR
    Opinion of the Court
    Sierrita, 
    116 Ariz. at 204-07
    . Our supreme court concluded that under the
    Duval Sierrita approach, when considering the spare and replacement parts,
    "rather than view each item at a fixed point in time, without reference to its
    function, [a court] should apply the 'ultimate function' test: that is, it should
    examine how the item functions in the industrial process at issue to see
    whether the item qualifies for" the exemption. Capitol Castings, 
    207 Ariz. at 450
    , ¶ 21 (citing Duval Sierrita, 
    116 Ariz. at 204
    ). The belt, pipes, and booster
    pumps were considered under an "'integrated approach' that addresses
    how the item is used in the industrial processes described in [the statute]
    and considers the item's necessity to the process." 
    Id.
     (citing Duval Sierrita,
    
    116 Ariz. at 205
    ). "The Duval Sierrita approaches allow some items that
    would not ordinarily be considered 'machinery' or 'equipment' to qualify
    for the . . . exemption if they function as a necessary part of an integrated
    process." Capitol Castings, 
    207 Ariz. at 450, ¶ 21
    .
    ¶12            The Department conceded the items at issue in Duval Sierrita
    were "machinery or equipment." 
    116 Ariz. at 203
    . But in other situations,
    "items not traditionally considered to be machinery or equipment may
    qualify as such depending on their function in the process." Capitol
    Castings, 
    207 Ariz. at 450, ¶ 22
    ; see CCI Europe, Inc. v. Ariz. Dep't of Revenue,
    
    237 Ariz. 50
    , 53, ¶ 12 (App. 2015) (finding "software is machinery or
    equipment" (citing Capitol Castings, 
    207 Ariz. at 450, ¶ 22
    )). For example,
    our supreme court recognized that certain "chemicals, 'sulfuric acid, LIX,
    and Orfom 7,' qualified as machinery or equipment" under the exemption
    "[b]ecause the chemicals functioned like items traditionally thought to be
    machinery or equipment" in the process of extracting copper from ore.
    Capitol Castings, 
    207 Ariz. at 450
    , ¶ 22 (citing Ariz. Dep't of Revenue v. Cyprus
    Sierrita Corp., 
    177 Ariz. 301
    , 302-04 (Ariz. Tax Ct. 1994)); see also RenalWest
    L.C. v. Ariz. Dep't of Revenue, 
    189 Ariz. 409
    , 414 (App. 1997) (holding that a
    chemical solution used in dialysis is machinery or equipment (citing Cyprus
    Sierrita, 
    177 Ariz. at 303
    )).
    ¶13            Thus, we must "consider a number of factors to determine
    whether the item qualifies" for the exemption. Capitol Castings, 
    207 Ariz. at 450, ¶ 24
    . "First, a court must apply flexible and commonly used definitions
    of machinery and equipment within the relevant industry." 
    Id.
     Then,
    "bearing in mind these flexible definitions, a court should examine the
    nature of the item and its role in the operations." 
    Id. at 451, ¶ 25
    .
    6
    CARTER OIL v. ADOR
    Opinion of the Court
    ¶14            The parties do not offer a definition of "equipment"5 as that
    word is commonly used in the mining industry,6 but Capitol Castings
    defined "equipment" to include "the articles, implements, etc., used or
    needed for a specific purpose or activity." 
    207 Ariz. at 448, ¶ 12
     (quoting
    Webster's College Dictionary 442 (2d ed. 1997)). Capitol Castings also sets
    out several factors for courts to consider when examining the "nature of the
    item and its role in the operations." 
    207 Ariz. at 451, ¶ 25
    . The six factors
    are: (1) whether the item is "essential or necessary to the completion of the
    finished product[,]" (2) "[t]he prominence of an item's role in maintaining a
    harmonious 'integrated synchronized system' with the indisputably
    exempt items[,]" (3) "the nexus between the item at issue and the process of
    converting raw materials into finished products[,]" (4) "whether the item
    physically touches the raw materials or work in process[,]" (5) "whether the
    item manipulates or affects the raw materials or work in process[,]" and (6)
    "whether the item adds value to the raw materials or work in process as
    opposed to simply reducing costs or relating to post-production activities."
    
    Id.
     (citing Duval Sierrita, 
    116 Ariz. at 205-07
    ).
    ¶15            Applying these factors, we conclude the dyed diesel Hanson
    used was not machinery or equipment used directly in mining and
    processing. Dyed diesel's role in "the entire operation," Duval Sierrita, 
    116 Ariz. at 206
    , was vital but was not equivalent to the equipment and
    machinery it powered in Hanson's mining and processing operations.
    Unlike the sand in Capitol Castings, 
    207 Ariz. at 446-47, ¶ 3
    , or the sulfuric
    acid in Cyprus Sierrita, 
    177 Ariz. at 302
    , dyed diesel neither touched nor
    manipulated the raw materials. In Cyprus Sierrita, the mine sprayed sulfuric
    acid onto ore to strip away the copper from any attached impurities. 
    177 Ariz. at 302
    . The exempt items in Capitol Castings "had a close nexus to the
    process as they directly touched the raw materials in the process of
    converting them into the finished product." 
    207 Ariz. at 451, ¶ 26
    . In
    contrast, dyed diesel is the fuel that powered Hanson's exempt machinery
    and equipment, and was poured into the machinery's fuel tanks rather than
    onto the raw material. Although dyed diesel was necessary for Hanson's
    machinery to operate, as used here, it did not function "like items
    traditionally thought to be machinery or equipment." 
    Id. at 450, ¶ 22
    .
    5      Carter Oil does not argue on appeal that dyed diesel is "machinery."
    6      A dictionary published by the United States Bureau of Mines also
    lacked a definition of "equipment." See U.S. Dep't of the Interior, Bureau of
    Mines, Dictionary of Mining, Mineral, and Related Terms, 1103-04 (2d ed.
    1996).
    7
    CARTER OIL v. ADOR
    Opinion of the Court
    ¶16           Furthermore, as this Court previously noted, other statutes
    reflect "the Arizona Legislature's willingness to expressly exempt fuels
    from taxation in specific situations." Ariz. Elec. Power Coop., Inc. v. Ariz.
    Dep't of Revenue, 
    242 Ariz. 85
    , 89, ¶ 17 (App. 2017) (citations omitted). The
    statute delineating exemptions from the transaction privilege tax includes
    four different exemptions for "fuel." See A.R.S. § 42-5061(A)(22), (37), (46),
    (54). Tellingly, the statute provides separate exemptions both for
    "machinery and equipment" and the fuels required to power the exempted
    items.     Compare A.R.S. § 42-5061(B)(4) (exempting machinery and
    equipment used directly in electrical production) with A.R.S. § 42-
    5061(A)(37) (exempting certain fuels used to generate electricity); see also
    2018 Ariz. Sess. Laws, ch. 263, § 1 (2nd Reg. Sess.) (H.B. 2003) (conditionally
    exempting sales of coal). If, as Carter Oil argues, the statutory exemptions
    for "machinery or equipment" necessarily included the fuels that power
    such machinery or equipment, then these separate exemptions would be
    unnecessary. Because the legislature specifically provided an exemption
    for fuels, apart from machinery and equipment, elsewhere in the same
    statute, we cannot adopt such an expansive interpretation of "machinery
    and equipment" in § 42-5061(B)(1) and (2). See City of Flagstaff v. Mangum,
    
    164 Ariz. 395
    , 398 (1990) ("Where the legislature uses a term within one
    statute and excludes it from another, the term usually will not be read into
    the provision from which it was excluded.").
    ¶17           Finally, we "bear in mind that the goal of the exemption—
    promoting economic development—must not be frustrated by too narrow
    an application." Capitol Castings, 
    207 Ariz. at 451, ¶ 25
    . As discussed below,
    that goal is not frustrated by the taxation of dyed diesel used to power
    mining and processing equipment. The fuel Carter Oil sells to Hanson
    already receives favorable tax treatment in comparison to non-dyed diesel.
    Compare A.R.S. § 28-5606(B)(2) (twenty-six cents per gallon excise tax on
    non-dyed diesel) with A.R.S. § 42-5010(A)(1)(l) and (G) (five and six-tenths
    percent tax on retail sales).
    C.     A Separate and Specific Statutory Tax Scheme Applies.
    ¶18           "Words in statutes should be read in context in determining
    their meaning." Stambaugh v. Killian, 
    242 Ariz. 508
    , 509, ¶ 7 (2017). "Where
    we have a general statute and a specific statute that are in conflict, the
    specific governs." State v. Rice, 
    110 Ariz. 210
    , 213 (1973). "In construing a
    specific provision, we look to the statute as a whole and we may also
    consider statutes that are in pari materia—of the same subject or general
    purpose—for guidance and to give effect to all of the provisions involved."
    Stambaugh, 242 Ariz. at 509, ¶ 7.
    8
    CARTER OIL v. ADOR
    Opinion of the Court
    ¶19            The legislature does not hide fuel-tax exemptions. If it wished
    to exempt dyed diesel from the transaction privilege tax, then it would have
    done so plainly, not by expecting that the Department, taxpayers, and
    courts would interpret "equipment and machinery" to include "fuel." When
    legislatures create tax exemptions they "do so notoriously enough to attract
    investors, not surreptitiously enough to evade detection for half a century."
    United States v. Wells Fargo Bank, 
    485 U.S. 351
    , 357 (1988) (rejecting claim that
    Congress intended to "break new ground in tax law by cleverly hiding an
    estate tax exemption"); cf. Whitman v. Am. Trucking Ass'ns, 
    531 U.S. 457
    , 468
    (2001) (legislatures do not "hide elephants in mouseholes."). Further, "[t]he
    provision of one exemption in a statute implicitly denies the existence of
    other unstated exemptions." Ariz. Elec. Power, 242 Ariz. at 89, ¶ 17 (quoting
    State Comp. Fund v. Superior Court (EnerGCorp, Inc.), 
    190 Ariz. 371
    , 375-76
    (App. 1997)); see also Pima County v. Heinfeld, 
    134 Ariz. 133
    , 134 (1982) ("A
    well established rule of statutory construction provides that the expression
    of one or more items of a class indicates an intent to exclude all items of the
    same class which are not expressed.").
    ¶20           Separate from the transaction privilege tax, Arizona imposes
    a per-gallon excise tax on motor fuels, including non-dyed diesel. See A.R.S.
    § 28-5606; City of Mesa v. Killingsworth, 
    96 Ariz. 290
    , 296 (1964). The stated
    purpose of the diesel fuel tax is to "partially compensate this state for the
    use of its highways." A.R.S. § 28-5606(B). Accordingly, the legislature
    explicitly provided an exemption from the fuel tax for dyed diesel used in
    machines and vehicles that do not operate on state highways—such as the
    ones used by Hanson in this case. See A.R.S. § 28-5610(A)(8).
    ¶21            The legislature added the mining and processing exemptions
    to the transaction privilege tax in 1968. See 1968 Ariz. Sess. Law, ch. 2, § 1
    (3rd Spec. Sess.) (S.B. 4). At the time, non-dyed diesel used by on-highway
    vehicles was subject to both the transaction privilege tax and the fuel tax.
    See Op. Ariz. Att'y Gen. I80-087. In 1980, however, the legislature enacted
    an exemption from the transaction privilege tax for non-dyed diesel taxed
    as fuel. See 1980 Ariz. Sess. Laws, ch. 2, § 1 (3rd. Spec. Sess.) (H.B. 2001); see
    also A.R.S. § 42-5061(A)(22). The legislature did not likewise exempt dyed
    diesel used in off-highway vehicles—such as the ones used by Hanson in
    this case. The result is that the fuel tax, not the transaction privilege tax,
    applies to fuel, including non-dyed diesel, used to power vehicles on the
    road. Dyed diesel, which powers off-road equipment and vehicles, remains
    subject to the transaction privilege tax but not the fuel tax. Had the
    legislature wanted to exempt diesel used in mining and processing from
    the transaction privilege tax, it could have done so, either in the original
    1968 mining and processing exemptions, or in the 1980 amendment
    9
    CARTER OIL v. ADOR
    Opinion of the Court
    exempting non-dyed diesel. It did neither. We infer that the legislature's
    choices were deliberate and that it intended that dyed diesel not taxed as
    fuel should remain subject to the transaction privilege tax. This
    interpretation gives "effect to all of the provisions involved." Stambaugh,
    242 Ariz. at 509, ¶ 7.
    ¶22          Accordingly, we conclude that Carter Oil's sale of dyed diesel
    to Hanson is subject to Arizona's transaction privilege tax. Because we
    determine that the dyed diesel is not machinery or equipment used directly
    in mining or processing operations under the test established by our
    supreme court in Capitol Castings, we need not consider the Department's
    remaining arguments.
    D.     Other Exemption Decisions Are Distinguishable.
    ¶23          Carter Oil relies on two earlier opinions of this Court, Chevron
    and Empire Southwest, in which we held that "industrial oils and greases"
    and a "fuel truck" used in mining operations are exempt from the
    transaction privilege tax. However, neither case is dispositive as to dyed
    diesel.
    ¶24             In Chevron, the plaintiff sought a tax refund for the sale of
    "industrial oils and greases" for use in mining and metallurgical operations.
    238 Ariz. at 520, ¶ 1. The industrial oils and greases at issue were "engine
    oil, gear oil, grease, and open gear lube." Id. at 520, ¶ 4. We concluded,
    "based on the uncontroverted evidence, . . . that the oils and greases
    function[ed] as equipment in [the] operations." Id. at ¶ 21.
    ¶25            The approach we adopted in Chevron for industrial oils and
    greases is inapplicable to dyed diesel. First, as discussed above, the
    legislature provided a separate and distinct fuel tax exemption for dyed
    diesel and did not apply that exemption to the transaction privilege tax. No
    similar situation exists for "industrial oils and greases." Second, although
    dyed diesel has some lubricating properties, that does not mean the
    legislature intended dyed diesel to be exempt as a lubricant. The legislature
    may tax some items and simultaneously exempt other seemingly similar
    items. See, e.g., Ariz. State Tax Comm'n v. Lawrence Mfg. Co., 
    15 Ariz. App. 486
    , 489-90 (1971) (upholding statutory scheme that taxed leases of mining
    equipment but exempted sales of mining equipment). Finally, our decision
    in Chevron was "consistent with the Department's policy which considers
    'items such as antifreeze, motor oil, transmission fluid, bearing grease and
    windshield washer solution . . . a part of the vehicle, and therefore, qualify
    for exemption.'" Chevron, 238 Ariz. at 524, ¶ 22 (quoting Transaction
    10
    CARTER OIL v. ADOR
    Opinion of the Court
    Privilege Tax Ruling TPR 2003–2, 
    2003 WL 23178083
     (Ariz. Bd. Tax App.
    Dec. 4, 2003)). Although the Department in Chevron attempted to
    distinguish its contrary positions, we reasoned that the "same logic applies
    to the oils and greases." Chevron, 238 Ariz. at 524, ¶ 22. After Chevron was
    decided, our legislature specified that courts shall determine all questions
    of law "without deference to any previous determination that may have
    been made on the question by the agency." Compare A.R.S. § 12-910(E)
    (2019) with A.R.S. § 12-910(E) (2016); cf. also City of Phoenix v. Orbitz
    Worldwide Inc., 
    247 Ariz. 234
    , 289, ¶ 52 (2019) (Timmer, V.C.J., dissenting)
    (citing Scottsdale Healthcare, Inc. v. Ariz. Health Care Cost Containment Sys.
    Admin., 
    206 Ariz. 1
    , 8, ¶ 27 (2003) for the proposition that an "agency
    interpretation of a statute is given weight"). Accordingly, if the Department
    had treated dyed diesel as "equipment" subject to the exemption, we would
    not defer to that interpretation, nor defer to the Department's longstanding
    and consistent position that dyed diesel is subject to the transaction
    privilege tax. See A.A.C. 15-5-1846 (Eff. Nov. 7, 1978) ("Sales of diesel fuel
    to consumers are taxable.")7; Cyprus Bagdad Copper Corp. v. Ariz. Dep't of
    Revenue, No. 683–89–U, 
    1990 WL 177835
     (Ariz. Bd. Tax. App. June 26, 1990)
    (providing that because diesel used at a copper mine is "exempted and not
    subject to the [diesel] fuel tax under title 28, it is not exempted and is subject
    to the use tax of title 42.").
    ¶26              Our decision in Empire Southwest is similarly unhelpful to
    Carter Oil. There, we concluded that a fuel truck was "used directly in the
    process of extracting ore from the earth [and therefore] exempt from
    transaction privilege tax." 244 Ariz. at 545, ¶ 16. There was no dispute in
    Empire Southwest about whether the fuel truck was "machinery or
    equipment." Instead, the case turned solely on whether "the [t]ruck was
    'used directly in the process of extracting ores or minerals from the earth.'"
    Id. at 544, ¶ 7 (emphasis omitted) (quoting A.R.S. § 42-5061(B)(2)). The mine
    used the truck to transport "fuel and lubricants from the pit rim to
    equipment located several hundred feet below [which] require[d] refueling
    every twelve hours." Empire Sw., at 545, ¶ 12. We found the truck operated
    similarly to the booster pumps needed to transport water to the mill in
    Duval Sierrita, "as part of an integrated synchronized system." Empire Sw.,
    244 Ariz. at 545, ¶ 14-15 (citing Duval Sierrita, 
    116 Ariz. at 206
    ). Thus, Empire
    7      A.A.C. 15-5-1846 was renumbered and partially amended in 1985,
    1993, and 2004. See A.A.C. R15-5-3004 (Eff. July 23, 1985), R15-5-127 (Eff.
    Aug. 9, 1993), and R15-5-127 (Eff. Dec. 4, 2004) ("Gross receipts from the sale
    of dyed diesel fuel are subject to transaction privilege tax.").
    11
    CARTER OIL v. ADOR
    Opinion of the Court
    Southwest is silent about whether the diesel that powers machinery or
    equipment is also machinery or equipment.
    ¶27           Because fuel does not touch, manipulate, or add value to the
    raw materials in the mining process, it is neither machinery or equipment
    nor an item "traditionally thought to be machinery or equipment." Capitol
    Castings, 
    207 Ariz. at 450, ¶ 22
    . Our decision is consistent with our analysis
    in Chevron and Empire Southwest. "Equipment or machinery" includes
    trucks and the parts needed to be replaced on such machinery or
    equipment, whether air filters or lubricating oil, but, absent an express fuel
    exemption, it does not include the fuel necessary to power the machinery.
    CONCLUSION
    ¶28           The question presented is purely one of law. "[W]here the
    issues can be decided as a matter of law, we have the authority both to
    vacate the trial court's grant of summary judgment in favor of one party
    and to enter summary judgment for the other party if appropriate."
    Anderson v. Country Life Ins. Co., 
    180 Ariz. 625
    , 628 (App. 1994). For the
    foregoing reasons, we reverse the judgment of the tax court and direct entry
    of judgment for the Department on remand.
