Motor Oil Info

A cylinder liner from the DT466 Waste Co. truck, still has the OEM cross-hatch pattern in the cylinder, is still evident, after nearly 8,000 hours of operation,demonstrating AMSOIL Synthetic Diesel Oil’s excellent wear control in spite of the extreme shaking, jarring and revving the motor is subjected to on a daily basis. If sufficient lubrication is not provided, excess heat may cause thermal expansion, which can force the cylinder out of round and significantly increase the potential for wear.

An oil’s ability to maintain corrosion protection throughout its service life is measured by Total Base Number (TBN). AMSOIL Synthetic 15w-40 Diesel and Marine Oil is formulated with a high 12 TBN to ensure corrosion protection from combustion blow-by and exhaust gas recirculation (EGR) for the life of the oil. AMSOIL Synthetic Diesel Oil displayed excellent TBN retention ability for the entire 983-hour drain interval.
