Use unleaded premium gasoline with an octane

If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:

. Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.

. Avoid full throttle driving and abrupt acceleration.

However, for maximum vehicle performance,
the use of unleaded premium
gasoline is recommended.
