(a) Any manufacturer who shall use any taxable gasoline, on which the gasoline tax has been paid, in the manufacture of a premixed engine fuel containing gasoline and oil, sold in containers of one gallon (1 gal.) or less and produced for use in two-cycle engines and not for use in the propulsion of an aircraft, vessel or other vehicle, shall be entitled to a refund of gasoline tax paid under § 67-3-201 except one cent (1¢) per gallon; but there shall be no refund of the special privilege tax on gasoline imposed under § 67-3-203 or the environmental assurance fee on gasoline imposed under § 67-3-204.

(b) The claim for refund filed pursuant to this section may be filed at the end of each calendar quarter but no later than one (1) year from the date of the last purchase represented in the claim. The minimum amount of such claim is two hundred fifty dollars ($250). Supporting documentation shall be submitted with the claim as the commissioner may require. If the minimum is not met in one (1) quarter, then the claim amount can be carried over to and used in subsequent quarters, but not for longer than a total period of two (2) years.
