ENGINE OIL

CAUTION
• Only use the engine oil
specified. Other engine oils
may affect warranty coverage,
cause internal engine
components to seize, or
shorten engine life.
• Prevent dirt and debris from
contaminating engine oil.
Carefully clean the oil
cap / dipstick and the
surrounding area before you
remove the cap.
• NEVER mix different types of
engine oil. This may adversely
affect the lubricating
properties of the engine oil.
• NEVER overfill. Overfilling may
result in white exhaust smoke,
engine overspeed or internal
damage.
