Esso Synergy Supreme+ 99 – The Smart Choice for Performance and Protection
Esso Synergy Supreme+ 99 guide by Stephen Buckley, Sales Manager & Senior Fuel Analyst at Fleetmaxx Solutions
When you run a fleet or rely on your vehicle for business, every drop of fuel matters. Cleaner engines perform better, last longer, and ultimately save you money at the pump. That’s why at Fleetmaxx Solutions, we’re proud to supply Esso Synergy Supreme+ 99 – a premium petrol that’s engineered to deliver up to 3x cleaner engine performance compared to regular petrol.*
Cleaner engines run smoother and go further
Esso Synergy Supreme+ 99 is specially formulated to triple clean and protect your engine, helping you get more miles per tank and fewer stops to refuel. It’s packed with advanced cleaning molecules that work hard to remove deposits, improve efficiency, and reduce friction between moving parts.
With a higher octane rating (99 RON) than standard unleaded (95 RON), you’re giving your engine a fuel that helps it perform closer to its best. Every litre also includes up to 5% ethanol, supporting lower emissions without compromising on quality or driveability.
Cleaner engines can save fuel and reduce the time you spend filling up.
Engine protection you can trust
A smoother, cleaner engine is a protected engine – and that’s exactly what Esso Synergy Supreme+ delivers.
Formulated with three powerful active detergents, this advanced fuel provides three-way protection against:
-
Deposits – to keep injectors and valves clean.
-
Corrosion – to shield vital metal parts from rust.
-
Wear and tear – to reduce friction and extend component life.
Think of it as a triple defence system, keeping your engine performing like new and helping avoid costly maintenance in the long term.
The science behind Synergy fuels
Esso’s fuel scientists have developed an 8-ingredient formula that makes Synergy fuels stand out from the crowd. Each component plays a critical role in cleaning, protecting, and optimising your vehicle’s performance:
- Fuel Detergents (1 & 2) – Deliver superior cleanliness for both port fuel injection and direct injection engines. Cleaner parts mean better mileage, power, and protection.
- Fuel Detergent 3 – A next-generation cleaning agent specifically designed for modern direct-injection engines.
- Friction Modifier – Reduces friction between moving parts, cutting wear and helping your engine run more efficiently.
- Corrosion Inhibitor – Guards against rust in your fuel system and key engine components.
- Demulsifier – Prevents water build-up in your tank, ensuring clean, pure fuel reaches your engine.
- Solvent Fluid – Keeps all additives stable and effective, even in extreme cold.
- Esso Marker – Ensures the right additive balance every time you fill up.
Together, these ingredients are the result of decades of Esso research and engineering – creating a fuel that not only powers your engine but protects it too.
What about diesel drivers?
If you’re running diesel engines, Esso Synergy Supreme+ Diesel is just as impressive. It contains double the detergent of standard diesel, giving your engine a deeper clean for improved responsiveness, less wear, and better fuel economy. Cleaner injectors mean more precise combustion, smoother performance, and a noticeable reduction in emissions.
