Full Synthetic Heavy Duty Diesel Engine Oil

MAG 1 Full Synthetic Heavy Duty Diesel Engine Oil is designed to provide the highest levels of protection and performance from our most advanced technology and formulations.

PROTECTION FOR TODAY’S ENGINE DESIGNS

As today’s engines are evolving and heavy duty engine manufacturers are recommending thinner, lighter oils, MAG 1® has evolved right along with them. Only the most advanced engine oils meet the difficult challenges of effectively balancing durability, extending drain intervals and protecting emissions control devices.

UNSURPASSED PROTECTION, EVEN IN THE LIGHTEST VISCOSITY

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 also delivers greater horsepower and improved fuel economy.
