What about gasoline with blending materials that
contain oxygen (oxygenates), such as
MTBE
or alcohol?
MTBE
is
“methyl tertiary-butyl ether.” Fuel that is no
more than
15%
MTBE
is fine for your vehicle.
Ethanol
is ethyl
or
grain alcohol. Properly-blended fuel
that is no more than
10%
ethanol
is fine for your
vehicle.
Methanol
is methyl or wood alcohol.
NOTICE:
Fuel that is more than
5%
methanol
is
bad for
your vehicle. Don’t use it. It can corrode metal
parts
in
your fuel system and also damage plastic
and rubber parts. That damage wouldn’t be
covered under your warranty. And even at
5%
or
less, there must be “cosolvents” and corrosion
preventers in this fuel to help avoid these
problems.
Fuels
in Foreign
Countries
If you plan on driving in another country outside the
U.S.
or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that means costly repairs that wouldn’t be covered
by your warranty.
To
check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
