NOTE: To prevent extensive engine wear or
damage, never run engine with oil level
below or above operating range
indicator on dipstick (T).
Ensure engine is cool. Clean dipstick area of
any debris.
1. Remove dipstick (T); wipe oil off. Reinsert
dipstick (T) into tube; press completely down.
2. Remove dipstick (T); check oil level. Level
should be at top of indicator on dipstick (T).
3. If oil is low on indicator, add oil up to top of

Change Oil and Filter
Change oil while engine is warm.
1. Clean area around dipstick (T) and oil drain
plug (U). Remove oil drain plug (U) and
dipstick (T). Allow oil to drain completely.
2. Clean area around oil filter (V). Place a
container under filter to catch any oil and
remove filter. Wipe off mounting surface.
Reinstall oil drain plug (U). Torque to 10 ft. lb.
(13.6 N·m).
3. Place new filter in shallow pan with open end
up. Fill with new oil until oil reaches bottom of
threads. Allow 2 minutes for oil to be
absorbed by filter material.
4. Apply a thin film of clean oil to rubber gasket
on new filter.
5. Refer to instructions on oil filter (V) for proper
installation.
6. Fill crankcase with new oil. Level should be
at top of indicator on dipstick (T).

● Octane rating of 87(R+M)/2 or higher.
● Research Octane Number (RON) 90 octane
minimum.
● Gasoline up to 10% ethyl alcohol, 90%
unleaded is acceptable.
● Methyl Tertiary Butyl Ether (MTBE) and
