Gasoline Specifications (U.S. and Canada Only)

Cadillac CTS / Cadillac CTS 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.
