When to Add Engine Oil If the oil is at or below the ADD line, then you will need to add at least one quart 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 5-111. Notice: Do not add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged. See Engine Compartment Overview on page 5-12 for the location of the engine oil fill cap. What Kind of Engine Oil to Use Look for two things: • GM6094M Your vehicle's engine requires oil meeting GM Standard GM6094M. You should look for and use only an oil that meets GM Standard GM6094M. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through. 5-14
