Diesel fuel economy

Mobil Delvac 1 helps diesel fuel economy

As every owner/operator or 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, such as Mobil Delvac 1™ LE 5W 30, 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, have demonstrated potential fuel economy advantages of up to 1 percent versus conventional mineral lubricants. What’s more, Mobil Delvac 1™ fully synthetic heavy-duty engine oils provide powerful overall protection.


*Compared to conventional mineral oils, Mobil Delvac 1 LE 5W-30 offers 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.
