The world-class scientists at Esso and Mobil are always working to make petrol better to help your engine run more efficiently, and leave cleaner emissions. So, we started at the molecular level to make petrol that helps clean your car's intake valves for great performance. It's just one more way we make petrol work harder for you. Now that's a smart choice.

In Malaysia, Synergy petrol is available in two variants: Synergy F-1 – a high-octane premium unleaded petrol (minimum RON 97), and Synergy 5000 – a lower octane unleaded petrol (minimum RON 95).

Both Synergy F-1 and Synergy 5000 are formulated with a multi-functional detergent additive that increases the efficiency of your engine in many ways.

The detergent in this additive cleans and maintains cleanliness in the engine, fuel injectors, inlet valves and throughout the engine's intake system. This fully synthetic petrol additive also helps to minimize the build-up of harmful deposits, thus improving performance.

The efficiency doesn't stop here. There's also a corrosion inhibitor that protects your vehicle's petrol system from rust, which can cause rough engine idling or stalling.

Whether you choose our Synergy 5000 or the premium Synergy F-1, you will enjoy better efficiency.
