Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
IMPROVED GASOLINES
Toyota does not recommend the use of
gasolines that contain MMT. If fuels con-
taining MMT are used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Toyota dealer for ser-
vice.
The American Automobile Manufacturers
Association (AAMA) has developed
specification of improved gasolines. The
AAMA specification offers optimal fuel
information for better vehicle perfor-
mance and better protection of your en-
gine.

If you use 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% ethanol.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no need
of concern.
GASOLINES CONTAINING MTBE
Gasohol is a mixture of gasoline and etha-
nol.
Gasolines that contain MTBE (Methyl

gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
Toyota recommends use of gasolines
that contain detergent additives to
avoid build−up of engine deposits.
If the use of gasolines containing MTBE
causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE.
For further details, ask your Toyota dealer
or a local gasoline retailer.
