BDifficulty 2/5

Should you fill a vehicle with fuel that does not meet its manufacturer’s compatibility specifications?

Correct answer

No, it can damage the engine or fuel system.

No; it can damage the engine or fuel system. Use manufacturer-approved fuels, observing applicable type, quality, octane or cetane rating and blend limits. A fuel different from the preferred option may be valid if the manual permits it; a recommendation must not be confused with a ban on every compatible alternative. If incompatible fuel is added by mistake, do not start the engine and seek assistance.
