Engineered with 7 key ingredients to help you get better gas mileage,** Synergy gasolines provide lower emissions and improved engine responsiveness** and are designed to provide corrosion protection and improved performance compared with gasolines meeting minimum government detergency standards. In addition, Exxon and Mobil Synergy™ gasoline contains significantly higher detergent levels than EPA requirements and has passed a series of deposit control performance tests, resulting in it being certified TOP TIER®.
Engineered with 7 key ingredients, working together for better gas mileage.*
Meet the Team
Fuel detergent 1 – helps provide excellent protection against intake valve deposits in traditional PFI (Port Fuel Injector) injection engines
Fuel detergent 2 – helps provide Intake Valve Deposit protection for PFI engines and also provides additional protection for modern Direct Injection engines. Cleaner engine parts can lead to better gas mileage
Anti-adhesion compound – helps prevent fuel detergents from forming a sticky film on the intake valves, which in turn helps prevents cold start problems at cold temperatures
Corrosion inhibitor – helps prevent rust in fuel distribution systems and/or key engine parts the fuel comes into contact with, such as the gas tank and the intake valves
Demulsifier – helps keep water from getting entrained in our additive in the distribution system. Helps prevent accumulation of water in your gas tank by allowing it to be separated and removed
Solvent fluid – enables the additive ingredients to stay mixed and to flow, and not freeze at very cold temperatures
Marker molecules – ensures we can determine if the correct amount of our unique additive is added to our gasoline
Synergy Diesel Efficient™ for passenger vehicles
Next-generation diesel starts here.
Synergy Diesel Efficient diesel fuel was developed in the same laboratories as Exxon/Mobil racing fuels. It has been engineered to improve fuel economy (2% on average*), boost engine performance, reduce maintenance and provide cleaner emissions, letting you drive cleaner, smarter and longer.
Formulated with the latest breakthrough technology — and rigorously tested in the lab and on the road — it is the first diesel fuel widely available in the US with a proprietary formulation that helps you get more out of every gallon.
*Fuel economy improvement is based on Synergy Diesel Efficient compared to unbranded diesel fuel without detergent additive. Vehicle testing showed an average fuel economy improvement of 2 percent. Actual benefits will vary depending on factors such as vehicle/engine type, driving style and diesel fuel previously used.
