Increase fuel economy
Using Mobil Diesel Efficient fuel, Holland Special Delivery experienced an average 2% increase in fuel economy, fewer active re-gens and a restoration in the performance of their trucks.*
“2% fuel economy. Fewer active re-gens. It’s a no-brainer.”
Jim Albers, CEO, Holland Special Delivery
Avoid fleet downtime
When drivers and owner-operators at Challenger Motor Freight in the U.S. and Canada used Mobil Diesel Efficient fuel, their trucks had better fuel mileage and restored performance.*

**Mobil Diesel Efficient fuel claims are based on internal and/or third-party engine/vehicle testing, laboratory testing, and/or industry or other scientific literature. Basis for comparison for all claims is versus unadditized diesel. Fuel economy and tailpipe CO2 emissions testing was performed at independent testing labs in the UK and US using on-road third-party customer trucks using our first generation detergent additive package. Our new second generation detergent additive package is expected to have similar or better cleaning performance compared to the first generation additive package based on internal and/or third-party engine/vehicle testing and laboratory testing. Actual results may vary based on factors such as vehicle type, engine type, driving behavior, and other factors. Mobil Diesel Efficient fuel may be used in other heavy-duty and light-duty vehicles, but 2% average fuel economy improvement claim does not apply. Concentration and availability of our proprietary first and second generation additive packages may vary.

Additive concentration and availability of winterized Exxon Diesel Efficient fuel may vary.
