Esso Diesel Efficient™️ Fuel
Pre-additized Esso Diesel Efficient increases fuel economy by 2% versus unadditized diesel. That means less from your wallet, and more from your engine — from more power to increased responsiveness.
It's treated with a patented additive package designed to clean up both internal injector deposits and nozzle deposits. Esso Diesel Efficient not only helps prevent those deposits from forming; it also cleans up any existing deposits to help boost engine power and reduce emissions.

*Applies to Diesel Efficient fuel compared to diesel fuel without detergent additive. Diesel Efficient fuel claims are based on internal and/or third-party engine/vehicle testing, laboratory testing, and/or industry or other scientific literature. 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. Concentration and availability of our proprietary first and second generation additive packages may vary.
**All claims are based on comparison of Esso Supreme premium gas to gasoline meeting minimum Canadian government detergency standards in port fuel injected engines. Actual benefits are based on continuous use and may vary depending on vehicle type, driving style, and gasoline previously used. Concentration and availability of our proprietary additive package may vary.
