Monograde Heavy Duty Diesel Engine Oil

Heavy Duty Engine Oil

Protection and Performance

Only the most advanced engine oils meet the difficult challenges of effectively balancing durability, extending drain intervals and protecting emissions control devices.

Excellent Quality and Protection

MAG 1® with FMX® Technology provides unsurpassed protection in every viscosity. FMX Technology creates a strong, durable and high-performing level of protection that controls friction and reduces metal-to-metal contact.
