Gasoline Specifications (U.S. and Canada Only)

Buick LaCrosse / Buick LaCrosse Owners Manual / Driving and Operating / Fuel / Gasoline Specifications (U.S. and Canada Only)

At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB-3.5 or 3.511 in Canada.

Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Fuel Additives for additional information.
