If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE
causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. GASOLINES CONTAINING ALCOHOL
If the use of gasohol in your Toyota, be
sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethonol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methonol. If you use
gasoline containing methonol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.
Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle perfor-
mance problems.
If driveability problems are en-
countered (poor hot starting, va-
porizing, engine knock, etc.), dis-
continue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
