An octane booster increases the octane rating of your petrol, helping to prevent engine knocking caused by premature fuel ignition. This allows your engine to run smoother and more efficiently, especially under heavy load or high-performance conditions. Using an octane booster can boost throttle response, protect engine components, and in some cases, improve fuel economy.
Our range also includes other petrol fuel additives such as powerful engine cleaners that help keep your entire fuel system running at optimum efficiency, reducing deposits in injectors and valves. We also have a selection of lead replacement products for older cars, plus an even wider selection of car additives and flushes like fuel system cleaners and oil system additives and flushes that you might be interested in.
We only stock products from leading automotive brands like Millers Oils and more, trusted by drivers and mechanics across the UK for their quality and reliability. When you shop octane boosters and additives for petrol at Opie Oils, you can be confident you’re giving your vehicle the best possible care.
Octane boosters can be used every time you fill up. For other fuel additives, it generally depends on your car and the additive you're using. Always check the product instructions for the best results.
Yes, fuel additives can work when used correctly for the right purpose. However, their effectiveness can vary depending on the product quality, the condition of your vehicle, and how regularly they’re used. For best results, choose reputable brands and always follow the instructions on the label.
Despite what many think, adding an octane booster doesn’t automatically increase performance. Unless the engine is tuned to run on higher octane levels or the ECU can adapt to higher levels, then increasing the octane level will make little or no difference.
