86.513-2004—Fuel and engine lubricant specifications.

Section 86.513-2004 includes text that specifies requirements that differ from § 86.513-94. Where a paragraph in § 86.513-94 is identical and applicable to § 86.513-2004, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved]. For guidance see § 86.513-94.” Where a corresponding paragraph of § 86.513-94 is not applicable, this is indicated by the statement “[Reserved].”
(a) Gasoline. (1) Gasoline having the following specifications will be used by the Administrator in exhaust emission testing of gasoline-fueled motorcycles. Gasoline having the following specifications or substantially equivalent specifications approved by the Administrator, shall be used by the manufacturer for emission testing except that the octane specifications do not apply.
