"L" Low
"H" High
Perform this maintenance with the engine stopped.
Note: Ensure that the engine is either level or that the engine is in the normal operating position in order to obtain a true level indication.Note: After the engine has been switched OFF, wait for 10 minutes in order to allow the engine oil to drain to the oil pan before checking the oil level.
Maintain the oil level between the mark (L) and the mark (H) on the engine oil dipstick. Do not fill the crankcase above the "H".
Operating your engine when the oil level is above the "H" mark could cause your crankshaft to dip into the oil. The air bubbles created from the crankshaft dipping into the oil reduces the oils lubricating characteristics and could result in the loss of power.
Remove the oil filler cap and add oil, if necessary. Clean the oil filler cap. Install the oil filler cap. If an increase in the oil level is noticed, refer to Troubleshooting, "Oil Contains Fuel".
