About Unleaded Fuels

Unleaded fuels require a spark or ignition source in the engine to convert the fuel into energy. These fuels are rated according to RON.

RON is the worldwide standard used to test the compression rate of a fuel grade under controlled conditions to see the fuel’s ability to burn. The higher the RON, the more compression the fuel can withstand before ignition, and the better the fuel is for your car.

What octane rating should you use?

Inside the fuel flap on your car you’ll see the recommended octane rating to use.  If the recommendation is Unleaded Petrol Only, you can use ULP91. You can also use higher ratings (95 and 98.)

But if the recommendation is for Premium Unleaded Only, you should only use ULP95 or ULP98. If the recommendation is for ULP98 only, then always use that rating of fuel.


Be aware

While you can use 95 or 98 octane rating fuels in a car with an engine designed for 91, NEVER use a lower grade than the one recommended for your car. If your car is designed for 95, do not use 91, as this can cause damage to your engine.

What octane rating should you use?

With our three grades of unleaded fuel available at our consistently lower rates, you’ll find the right APW fuel to provide both performance and economy for your car – one that will also protect it against carbon deposits.


91 Unleaded.

Unleaded fuel with an octane level of 91-93%. This unleaded fuel can be used by most cars, unless your car requires Premium or Super Premium fuel. ULP91 provides a great combination of performance and economy.


95 Premium Unleaded.

Unleaded fuel with an octane level of 95-96% RON. It is a more refined fuel than 91 ULP and is often used by European cars because it helps their performance.


98 Premium Unleaded.

Unleaded fuel with the highest RON rating of 98%. It is highly refined and provides the best performance for a vehicle. It is the cleanest burning fuel, leaving the least carbon contaminants in the engine. It also provides great fuel economy.
