Esso Diesel Efficient™

The Esso Diesel Efficient™ fuel delivers both a cleaner engine and lower emissions, contributing to an impressive overall performance for your engine and your business.

Shown to reduce particulate matter and CO2 emissions, the fuel formulation keeps your fuel injector system cleaner, which helps to protect the fuel system and reduces maintenance downtime.

A special additive in the fuel inhibits water from reaching the metal surfaces thereby protecting your engine’s fuel system from corrosion, while an anti-foaming agent provides quicker refuelling.

Esso Diesel Efficient™ fuel helps your business save money and reduces overall fuel consumption.*



low emissions and fuel efficiency Lower emissions, cleaner air
In tests compared to standard Essodiesel, Esso Diesel Efficientfuel helped reduce NOx emissions by an average of 10%, particulate matter emissions by an average of 22% and carbon dioxide emissions by an average of 2.8%.*


Corrosion prevention and higher performance of Diesel Engine Protecting your engine fuel system from corrosion
A special additive helps provide excellent corrosion protection and contributes to the safeguarding of your fuel system.


Cleaner fuel injectors need less maintenance Cleaner fuel injectors need less maintenance
Esso Diesel Efficientfuel is formulated to protect your fuel injectors from internal and external deposits. This helps maintain optimal injection spray characteristics and promotes efficient mixing of fuel and air. Reduced deposits on fuel injectors help to provide improved combustion, engine power and performance and also lower fuel consumption, NOx, CO2 and particulate matter emissions.

*Independent tests performed at Millbrook Proving Ground Ltd., UK:
• Compared the performance in heavy-duty vehicles of Esso™ unadditised diesel with Esso Diesel Efficient™ fuel
• Used third-party customer trucks (Euro III and Euro V specifications)
• Covered approximately 110,000 miles/177,000 km
• Five months of normal daily on-road operations (motorway, rural, and urban environments)
• Took trucks out of service periodically for lab testing
• Test results range of 2.1% to 3.4% lower fuel consumption

Millbrook has expertise in automotive, test, and propulsion technologies and remain pioneers in low carbon development. (ISO Certification - ISO 17025, ISO 9001 and ISO 14001.)

Esso Diesel Efficient™ fuel claims are based on internal and third-party vehicle engine testing, laboratory testing, and/or industry or other scientific literature. Basis for comparison for all claims is versus Esso™ unadditised diesel. Vehicle type, engine type, driving behaviour, and other factors also impact fuel and vehicle performance, emissions, and fuel economy. Esso Diesel Efficient™ fuel may be used in all heavy-duty and light-duty vehicles, but results may vary. Fuel economy testing was performed in the UK using on-road trucks.
