10-2-4 Ranch
After testing Mobil Diesel Efficient fuel for only 65 hours, 10-2-4 Ranch saw cleaner injectors.* "Cleaner injectors mean a cleaner combustion and a more efficient engine," said Jeremy Gardner, Ranch Operations.
CALco Pallets Company
Not much goes to waste at CALco Pallets in Illinois. The pallet manufacturer saw fuel mileage increase and fuel filter clogs decrease,* which adds up when you’ve got a lot of city miles and tough Midwestern winters.
Holland Special Delivery
Holland Special Delivery experienced an average 2% increase in fuel economy, less DEF consumption, fewer active re-gens and an increase in the performance of their trucks.*

J & H Oil Company updated their diesel canopies with ExxonMobil branding, which drove consumer confidence and increased volume compared to those with no branding.
Product and Safety Data Sheets
*Exxon and 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 with heavy duty engines meeting US EPA 2010, Euro V, and/or Euro III emission regulations using on-road third-party customer trucks and our first generation detergent additive package. Our upcoming second generation detergent additive package is expected to have similar or better cleaning performance than that of the first generation additive package if compared in the same engine/vehicle type with the same test protocol. Actual results may vary based on factors such as vehicle type, engine type, driving behavior, and other factors. Exxon and 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.
