GHG17 DD Medium Duty Operators Manual NOTICE: If the oil level is constantly above normal and excess oil has not been added to the crankcase, consult with an authorized Detroit service outlet for the cause. Fuel or coolant dilution of lubricating oil can result in serious engine damage. 4. Check the oil level daily. With the engine stopped, use the oil dipstick and measure the oil level on crosshatch area on the dipstick. Figure below shows Maximum oil level (1) and Minimum oil level (2). If the oil reading is in the crosshatch area or between the bends of the dipstick, then the oil is at the proper level for engine operation. 5.
Add the proper grade of oil to maintain the satisfactory range on the dipstick. All diesel engines are designed to use some oil, so the periodic addition of oil is normal. Before adding lubricating oil, refer to "How to Select Lubricating Oil." Monitoring the Lubricating Oil Filter The engines are equipped with a single cartridge-style oil filter (3) that is part of the oil/coolant module (4). Incorporated into the housing is a drain back port which allows residual oil to be returned to the oil pan when the filter is removed. This design, including the cartridge-style element, allows for a more environmentally safe oil change. All information subject to change without notice.
