Protection, Performance, and Value


All Fleet Motor Oils



Today’s Heavy Duty Diesel Lubrication Needs Are More Demanding and Complex Than Ever


Heavy-duty diesel fleets and owner operators are caught in a squeeze today. With equipment costs continuing to spiral, the need to maximize equipment life has never been more important. Yet competitive pressures demand extended drain intervals. And the technology needed to meet new, more stringent emission requirements further severely stresses lubricant performance. Only the most advanced oils can meet the difficult challenge of effectively balancing durability, extended drain and emission control. Our formulation can also be used in newer engines equipped with Exhaust Gas Recirculation (EGR) devices.


No Other Heavy Duty Diesel Engine Oils Are More Advanced Than Mag 1 All Fleet


MAG 1 All Fleet Diesel Engine Oils are specially formulated with only the finest quality, hydrotreated, high viscosity index, paraffinic
base oils and the most advanced and rigorously-tested additive system to deliver protection and performance that can’t be beat. Nothing protects heavy duty diesel and gasoline engines better in critical performance areas:

High detergency and superior dispersancy keep engines clean and soot suspended in the oil despite longer drain intervals and increased soot loading.
Exceptional resistance to thermal degradation, even under the
most severe operating temperatures, prevents viscosity increase
and the deposit formation and wear that can result.
Superior anti-wear agents extend engine life despite high operating temperatures and extended service intervals.
Higher starting TBN provides added protection against acid buildup that can cause rust and corrosion.
Highly reliable performance over a wide range of temperatures,
including severe cold.
