Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.
Straight 30-weight oil is preferred. SAE IOW-30 oil
is not recommended above 32OF. Using this oil
substantially increases oil consumption and
combustion chamber deposits.
