Engine Oil If you have the LT1 engine, it's a good idea tocheck your engine oil level every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. ~ ~ If you have the LT5 engine, the best time to check your engine oil is when the engine is cold. If you run the engine,the engine oil won't drain back into thepan fast enough. Give the oil two hours to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. Turn off the engine and give the oila few minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. 6-12
