    Proof of performance for Special Diesel

    ExxonMobil Research & Engineering evaluated Mobil Special Diesel in industry-recognised tests simulating real-world operating conditions. Independent tests performed at Millbrook Proving Ground Ltd, UK^:

    • Compared unadditised diesel with Special Diesel
    • Used third-party customer trucks (Euro III and Euro V specifications)
    • Measured five months of normal daily on-road operations (motorway, rural and urban environments)
    • Covered over 125,000 km
    • Took trucks out of service periodically for lab testing

*Mobil Special Diesel performance claims are based on internal and third-party customer testing, laboratory testing and/or literature support. Fuel economy testing was conducted using on-road trucks comparing performance to unadditised diesel. Actual benefits may vary depending on factors such as engine type, driving style, and fuel previously used.
