Transmission oil
Make sure the transmission oil is at the specified
level. Add oil as necessary. (See pages 8-13 ~

cC
Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor
oils (often labeled “Energy Conserving”)
contain anti-friction additives which will
cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor
engine performance.
Recommended oil:
SAE 10W30
Recommended oil classification:
API Service SE, SF, SG type or higher
Oil quantity:
Total amount:
0.7 L
Periodic oil change:
0.65 L
