Conventional Heavy Duty Diesel Engine Oil

Heavy Duty Engine Oil

Featuring FMX® Technology System – Friction Management for Xtreme protection™. MAG 1® provides unsurpassed protection and performance.

Our conventional heavy duty diesel engine oils are for older engine and OEM specifications, but still improve performance, extend engine life and resist thermal breakdown.

Protection You Can Count On

MAG 1® engine oil provides outstanding technology for our heavier viscosities. These 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. 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 and operating conditions.
