Gasoline Specifications (U.S. and Canada Only)

GMC Sierra / GMC Sierra Owners Manuals / 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 on page 9‑75 for additional information.
