*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 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 new second generation detergent additive package is expected to have similar or better cleaning performance 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 behaviour, and other factors. Concentration and availability of our proprietary first and second generation additive packages may vary.
