gine internal parts such as valves, piston
rings, exhaust system, etc. _
Recommended fuel:

only with a research octane number of 91
or higher.

WARNING
_
Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.
Do not refuel right after the engine has
been running and is still very hot.
Be sure the fuel tank cap is closed secure-
ly.

CAUTION:Be sure to use motor oils that do not contain anti-
friction modifiers. Passenger car motor oils (often
labeled “Energy Conserving II”) contain anti-fric-
tion additives which will cause clutch and/or
starter clutch slippage, resulting in reduced com-
ponent life and poor engine performance.
