Synergy logo with 7 key ingredients copy Canada English

Enter the lab  

Born in the same ExxonMobil labs as our Formula 1 racing fuels, Synergy™ gasoline’s 7 key ingredients add up to our best fuel ever. Their powers combine to help provide better fuel economy, lower emissions and improved engine responsiveness.* Find out how each ingredient works:

Solvent Fluid #1

Changes in temperature can cause some ingredients to get jammed. Solvent Fluid helps break them up, preventing congealing and letting the good times flow.

Solvent Fluid #2

With so many ingredients working together, space can be tight. Solvent Fluid #2 works to concentrate and compact the Fuel Detergent so there’s more room to go around.

Anti-Adhesion Compound

Some ingredients like to stick around, leaving a film on your intake valves. Anti-Adhesion Compound shows them the door, preventing build-up to keep things running smoothly.

Corrosion Inhibitor

When you’re not looking, rust will try to make a move on key engine parts. That’s why we threw in some muscle – technically, Corrosion Inhibitor – to help shut down rust right from the start.


Did you know fuel can get out of shape? The Demulsifier works hard to help prevent fuel from holding onto excess water, which can wreak havoc in the distribution system.

Fuel Detergent

This ingredient does the dirty work, helping to scrub away deposits and protect your engine from build-up, which over time can affect performance.

Marker Molecules

It's not about working hard, but working smart – having the right information at the right time. Marker Molecules signal the dosage of the additive in the gasoline so the balance is perfecto.
