Premium Conventional Heavy Duty Diesel Engine Oil

Heavy Duty Engine Oil

Protection for Today’s Engine Designs and Fleets

As today’s engines are evolving and heavy duty engine manufacturers are recommending thinner, lighter oils, MAG 1® has evolved right along with them. Plus, we have outstanding technology for our heavier viscosities. Only the most advanced engine oils meet the difficult challenges of effectively balancing durability, extending drain intervals and protecting emissions control devices in modern and older engines.

Unsurpassed Protection

MAG 1® with FMX® Technology provides unsurpassed protection in every viscosity. Even our lowest viscosity oils protect better than thick oils of the past. FMX Technology creates a strong, durable and high-performing level of protection that controls friction and reduces metal-to-metal contact.

Our advanced oil technology actually improves oil properties over time, retaining viscosity, friction and anti-wear benefits, in spite of severe engine temperatures. MAG 1 can often improve fuel economy in the 10W-30 grade.
