FUEL AND OIL

GASOLINE RECOMMENDATION

Suzuki highly recommends that you use alcohol - free un-
leaded gasoline with a minimum pump octane rating of 87
(R+M / 2 method) or 91 (Research method). However, blends
of unleaded gasoline and alcohol with equivalent octane con-
tent may be used.
Allowable maximum blend of a single additive (not combina-
tion) :
5% Methanol, 10% Ethanol, 15% MTBE
If leaded gasoline is used, engine damage may re-
sult. Use only unleaded gasoline.

ENGINE OIL

Use only oils that are rated SE, SF, SG, SH, or SJ under the
API (American Petroleum Institute) classification system.
The viscosity rating should be SAE 10W-40.
If an SAE 10W-40 motor oil is not available, select an alterna-
tive according to the chart at right.
