Checking Engine Oil (ZO6 and ZR1) The engine oil dipstick handle is a yellow loop. The dipstick is located on the dry sump engine oil tank. See Engine Compartment Overview on page 5-14 for the location of the dry sump engine oil tank. These vehicles have a racetrack-ready dry sump engine lubrication system. This high-performance system operates differently than a standard engine lubrication system and requires a special procedure when checking the engine oil level. Follow this procedure closely when checking the engine oil level. The engine oil level must be checked when the engine is warm. Cold oil level in the dry sump tank may not indicate the actual amount of oil in the system. With this system, engine oil is contained in an external tank, separate from the engine. Under normal operating conditions, the oil pan under the engine does not store any oil. A. Engine Oil Dipstick B.
