10-10 Vehicle Care When to Add Engine Oil Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Checking Engine Oil It is a good idea to check the engine oil level at each fuel fill. 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 10‑8 for the location of the engine oil dipstick. 1. If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking your oil level too soon after engine shut off will not provide an accurate oil level reading. 2. 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. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade: Specification Use and ask for engine oils with the dexos™ certification mark. Oils meeting the requirements of your vehicle should have the dexos™ certification mark on the container. This certification mark indicates that the oil has been approved to the dexos™ specification. If the oil is below the MIN (minimum) mark on the dipstick, add one liter/quart of the recommended oil and then recheck the level. See "Selecting the Right Engine Oil" for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 12‑2. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 10‑8 for the location of the engine oil fill cap.
