WITH 6.2L DIESEL

TO: ALL CHEVROLET DEALERS


Engine damage could occur when using a "power fill" method of adding engine oil if the rate of fill is too fast.

Since the 6.2L lubrication system is a closed system, the rate of oil fill must be limited to prevent oil being draw into the intake manifold and cylinders through the crankcase ventilation system. Engine damage can occur if oil enters the cylinders.

Do not exceed an oil fill rate of seven (7) quarts in two
(2) minutes. Also, remove the oil level dipstick during filling operation; assure the dipstick is seated when replacing.

Depending on ambient temperatures and the viscosity of the oil being used, adjustments to fill equipment pressure may be required to limit the flow rate.
