additives. Engine oil also lubri-
cates the clutch and additives
could cause clutch slippage.

enters the crankcase.
10. Start the engine and warm up
for a few minutes. While
warming up, check for oil leak-
age. If oil leakage is found,
stop the engine immediately
and check for the cause.

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.
