SERVICE AND MAINTENANCE
ADVICE
• Any oil level above the "Inspection MAX" mark on the oil dipstick may cause
engine malfunctions. Change the oil whenever its level exceeds the "Inspection
MAX" mark.
• Fuel will gradually become mixed with the engine oil, thinning it out. Be sure to
change the oil at the specified intervals.
• The oil level read by the oil dipstick changes depending on the amount of time
that elapses after the engine is turned off. In order to confirm the correct oil
level, perform the check while the engine is cold before starting it. If the engine
has already been started, stop it after it has sufficiently warmed and wait 30
minutes or more before performing.
