Checking Engine Oil It's a good idea to check your engine oil 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. The engine oil dipstick handle is a yellow ring located in the engine compartment toward the passenger's side of the vehicle. See Engine Compartment Overview on page 5-72 for more information on location. Before closing the hood, be sure all filler caps are on properly. Then lift the hood to relieve pressure on the hood prop. Remove the hood prop from its slot in the hood and return the prop to its retainer. Then pull the hood down firmly to close. It will latch when dropped from 6 to 8 inches (15 to 20 cm) without pressing on the hood. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. 5-15
