Our Synergy Unleaded fuels
What’s in our Synergy Unleaded 95
We’ve increased the additives in our Synergy Unleaded 95, which help clean vital engine parts (like your car’s intake valves) and protect your engine from corrosion, all while you drive. Harmful deposits can build up in your engine over time which prevent your car from performing at its best. By helping to clean and remove these deposits our Synergy Unleaded 95 can help look after your engine, reduce your car’s emissions and give you more kilometres per fill so you can fill up less and save money.*
What’s in our Synergy Supreme+ Unleaded 98
Our Synergy Supreme+ Unleaded 98 has a higher octane and deeper cleaning power of our Synergy Unleaded 95, meaning it can help take better care of your engine and give you even more fuel economy and enhanced performance. It’s our best fuel for your engine protection.**
Our Synergy EuroDiesel
What’s in our Synergy EuroDiesel
The additives in our Synergy EuroDiesel are designed to help clean vital engine parts (like your car’s diesel injectors) and protect your engine from corrosion, all while you drive. Harmful deposits can build up in your engine over time which prevent your car from performing at its best. By helping to clean and remove these deposits our Synergy EuroDiesel can help look after your engine, reduce emissions, and give you improved engine performance and better fuel economy. In fact, when we tested it on everyday cars it gave them up to 26km more with every fill. That means you can fill up less and save money.***
