Ensure that oil level gauge (1) is seated.
If the engine is stopped, remove oil level gauge (1). Observe the oil level on "ENGINE STOPPED WITH OIL COLD" side (3).
If the engine is operating, reduce the engine speed to low idle. Remove oil level gauge (1) and observe the oil level on "ENGINE AT LOW IDLE WITH WARM OIL" side (4). The oil level should be between "ADD" mark (5) and "FULL" mark (6).
Engine damage can occur if the crankcase is filled above the "FULL" mark on the oil level gauge (dipstick).An overfull crankcase can cause the crankshaft to dip into the oil. This will reduce the power that is developed and also force air bubbles into the oil. These bubbles (foam) can cause the following problems: reduction of the oil's ability to lubricate, reduction of oil pressure, inadequate cooling, oil blowing out of the crankcase breathers and excessive oil consumption.Excessive oil consumption will cause deposits to form on the pistons and in the combustion chamber. Deposits in the combustion chamber lead to the following problems: guttering of the valves, packing of carbon under the piston rings and wear of the cylinder liner.If the oil level is above the "FULL" mark on the oil level gauge, drain some of the oil immediately.
If necessary, remove oil filler cap (2) and add oil. For the correct oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" topic (Maintenance Section). Do not fill the crankcase above "FULL" mark (6). Clean the oil filler cap. Install the oil filler cap.
Record the amount of oil that is added. For the next oil sample and analysis, include the total amount of oil that has been added since the previous oil change. This will help to provide the most accurate oil analysis.
