3. Wait at least five minutes (but not more than 20 minutes) to allow oil to drain and settle in the engine. 4. Remove the dipstick from the external engine oil tank and clean it with a lint-free paper towel or a cloth. Re-insert the dipstick into the external oil tank, pushing it all the way in until it stops. 5. Remove the dipstick from the oil tank and read the level on the cross-hatched area. Oil levels that fall in the cross-hatched area are normal. See Racing or Other Competitive Driving on page 4-15 for additional information on engine oil. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 5-14 for the location of the external engine oil tank and fill cap. When to Add Engine Oil (Z06 Only) If the oil is below the cross-hatched area at the tip of the dipstick, add at least one quart/liter of the recommended oil through the oil fill cap opening in the oil tank. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 5-103. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back into the oil tank when you are through. 5-20
