Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
Yo u may use unleaded gasoline b lended wi th al­
cohol o r MTBE (commonly referred to as oxygen ­
ates) if the blended mixt ure meets the fo llowing
criteria :
Blend of ga soline methanol (wood alcohol or
meth yl alcohol)
- Anti-knock index must be 87 AK I or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more tha n 2% co -solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Anti -knock index must be 87 AK I or higher .
- Blend must not co ntai n mo re t han
15% etha-
nol.
Blend of ga soline and MTBE
- Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades a re blended to pe rform es­
pec ially well for w in ter o r su mme r dr iv ing . D ur ­
i ng seasonal change-ove r, we s ugges t th at yo u
fill up at busy gas stat ions where the seasona l
adjustment is more likely to be made in time.
(D Note
- Meth ano l fuels which do not meet these re­
q uirements may cause corrosion and dam ­
age to plastic and rubber com ponents in the
fuel system.
- Do not use fue ls that fa il to meet the speci­
fied cr iteria in th is chapter .
-If you are una ble to dete rm ine whether or
not a part icu lar f uel blend meets the speci ­
fications, ask yo ur service station or its fue l

Operating your vehicle
outside the U.S.A. or

Government regulati ons in the United States and
Canada require that automobi les meet specific
emission regulations and safety standards.

If you plan to take your vehicle outside the conti­
nenta l limits of the United States or Canada,
there is the poss ibility that:
- un leaded fue ls for vehicles with catalytic con­
verter may not be available;
- fuel may have a considerably lower octane rat­
ing . Improper fuel may cause engine damage;
- service may be inadequate due to lack of proper
service facilities, tools or testing equipment;
- r eplacement parts may not be readily available.
