Checking Engine Oil It is a good idea to check the 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 loop. See Engine Compartment Overview on page 276 for the location of the engine oil dipstick. 1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level. 2. Pull 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. When to Add Engine Oil If the oil is below the lower hole at the tip of the dipstick (B), you will need to add at least one quart/liter of oil. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 368. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the upper hole (A) that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 276 for the location of the engine oil fill cap. Be sure to add enough oil to put the level somewhere in the proper operating range, between the holes on the dipstick. Push the dipstick all the way back in when you are through. 278
