also degrade functionality of critical
exhaust emissions components
such as spark plugs, oxygen
sensors, and the catalytic converter.
Damage from poor fuel quality,
water contamination, or if the
vehicle requires premium fuel,
operating the vehicle on gasoline
with a Pump Octane less than a 91
(R+M)/2, may not be covered.Prohibited fuels are: Gasolines
containing any methanol, MMT, an
organometallic octane enhancing
additive, and/or fuels containing
more than 15% ethanol in non-Flex
