286 MAINTAINING YOUR VEHICLE Checking Oil Level - 5.7L Engines To assure proper engine lubrication, the engine oil must be maintained at the correct level. Check the oil level at regular intervals, such as every fuel stop. The best time to check the engine oil level is about 5 minutes after a fully warmed engine is shut off or before starting the engine after it has sat overnight. Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level readings. Maintain the oil level in the "SAFE" range. Adding one quart (.9L) of oil when the reading is at the bottom of the "SAFE" range will result in an oil level at the top of the "SAFE" range on these engines. Engine Oil Dipstick CAUTION! Overfilling or underfilling will cause oil aeration or loss of oil pressure. This could damage your engine.
