Mobil Delvac 1 helps diesel fuel economy

Improving diesel fuel economy potential  

As every fleet manager knows, fuel expenses represent a large proportion of the cost of operating a commercial vehicle. Mobil Delvac 1™ products are engineered to help keep fuel and other operational costs in check by providing sustainability-related benefits through extended oil drain capability* and enhanced fuel economy potential** compared to conventional products.

How does fuel economy work?

As equipment ages, deposits and wear accumulate, resulting in a decrease in equipment efficiency. Low viscosity fully synthetic engine oils can help support engine efficiency and enhance fuel economy potential** by decreasing engine friction and offering exceptional flow characteristics at low temperatures. Reduced friction helps lessen deposit formation and wear, and optimize energy efficiency, allowing the equipment to maintain diesel fuel economy throughout its life.

Studies have shown that Mobil Delvac 1™ products, used in combination across the vehicle, have demonstrated potential fuel economy advantages of up to 1 percent versus conventional mineral lubricants. What’s more, Mobil Delvac 1™ full synthetic, heavy-duty engine oils provide powerful overall protection.

*Compared to conventional mineral oils, Mobil Delvac 1™ synthetic lubricants offer extended oil drain capability.

**Relative to conventional 15W-40 engine oil. Actual fuel economy improvement is dependent on vehicle/equipment type, outside temperature, driving conditions and your current fluid viscosity.
