CNG/LNG Engine Oil

Heavy Duty Engine Oil

MAG 1® CNG/LNG Engine Oil is a low-ash formulation designed for use in naturally aspirated and turbocharged four-stroke engines running on compressed natural gas (CNG) or liquefied natural gas (LNG) , in on-road service, and where SAE 15W-40 viscosity grade is recommended. This specialized oil is also recommended for use in some stationary natural gas engine applications where straight grade SAE 40 oils are typically specified but where operators demand multi-grade performance or where low-temperature start-up issues exist.

Protection for Today’s Engine Designs

As today’s engines are evolving, MAG 1 has evolved right alongside 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

MAG 1® with FMX® Technology provides unsurpassed protection. 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 excellent engine protection and oil life.

CNG/LNG Engine Oil featuring FMX® Technology and Evolutionary Performance™ 

MAG 1® CNG/LNG Engine Oils are specially engineered and formulated to provide:


Unsurpassed protection.


FMX® technology that minimizes friction and protects moving parts inside an engine.


Outstanding long-term performance in service applications operating under high-load, high-stress conditions and in all seasons.

Excellent oxidation and deposit control.
