Presenting fuels that clean your engine while you drive

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

What is the difference between Synergy Unleaded 95 and Synergy Supreme+ Unleaded 98?

Our Synergy Supreme+ Unleaded 98 has double the amount of detergent additive than our Synergy Unleaded 95, which helps give your engine an even deeper clean. And the cleaner your engine, the better it can perform. It also has a higher octane which helps to reduce knocking in higher performance cars.

Our Synergy Supreme+ Unleaded 98 is also designed to remove more of the nasty deposits in your engine, which helps to look after your engine, reduce your car’s emissions, and give you increased fuel economy.**

How our Synergy Unleaded fuels work

Tips

Keep your car well serviced, and make sure you check the oil levels regularly to help keep the engine happy, which in turn can help reduce CO₂ emissions.
Make sure you check your tyre pressure at least once a month and before you set off on a long journey. Under-inflated tyres can increase your fuel consumption by up to 4 percent.***
If driving at 100 kilometres per hour or more, keep the windows up. Open windows create a lot of aerodynamic drag, which can add to your fuel usage when driving at high speeds. Also, remove the roof rack if you’re not using it, for up to 10 percent savings on fuel.***
Don’t let your car idle for prolonged periods of time. If you get stuck in a traffic jam, consider switching off your engine, provided it is safe to do so. With modern car engines, you can begin driving soon after starting the engine to reduce unnecessary fuel consumption.
Air conditioning is known for using power, which consumes fuel and emits CO₂.*** If you’re driving at a low speed, switch it off and open your windows instead.
