Reference: JANUARY 27, 1999 ENGINE TIB, COMPONENT CODE 1300, "3300 GENERATOR SET OIL LEVEL MAINTENANCE AND HIGH OIL CONSUMPTION"Improper oil level maintenance practices can lead to reports of high oil consumption on 3300 engines. Solution:
Please use the following procedures for optimizing oil consumption and establishing the level of oil consumption for use in determining whether or not the engine may require additional investigation up to an including a piston change, as defined by Caterpillar Inc.:1. All oil level maintenance should be performed only when the engine is stopped, and after the oil has had a chance to drain into the oil pan from the cylinder block and the front gear train, and after the air in the oil has been allowed to dissipate (after approximately 20 minutes). If the engine is still running, a significant portion of the oil added in the filler will be hung up in the block and gear train. In addition, while the engine is running, the oil level in the pan actually is tilted and inconsistent. While the engine is running the oil in the pan is being pulled up on the right side of the pan and drawn down on the left side of pan because of crankshaft windage. This can result in inaccurate oil level reading on the dipstick. Only use the "Engine Running" marks on the dipstick to ensure there is sufficient oil in the pan to prevent a loss in oil pressure. DO NOT use the "Engine Running" marks on the dipstick for oil level maintenance.2. Ensure the engine is level before performing oil level maintenance. This is not normally a problem with commercial engines because they are typically leveled at installation. However, it is a critical consideration for mobile equipment that may be operation is on steep grades.3. Allow the oil level to drop to the "ADD" mark on the dipstick before adding new oil. Maintain the oil level below the "FULL" mark on the dipstick. Consistently adding oil to raise the oil level to the "FULL" mark can lead to overfill. This is because adding a whole quart/liter of oil can result in as little as a 3 mm change in oil level, depending on where the oil level is at the time (above the block/pan joint versus entirely in the sump).4. Check the "Engine Stopped" calibration of the oil level dipstick at an oil and filter change. After new filters have been installed and the proper amount of oil added to the pan, run the engine for a few minutes. Then stop the engine and allow the engine to stand for a few minutes more. BE SURE THE ENGINE IS LEVEL. Remark the "FULL" mark on the dipstick if necessary. Please consult the applicable Operation And Maintenance Manual for the correct oil fill volume for use in the dipstick calibration. The amount of oil volume between
