Performance & Efficiency With Our SUPER Range of Fuel Additives

Fuel additives are designed to enhance your vehicle's engine by boosting its performance, efficiency, and lifespan. Whether you drive a petrol or diesel vehicle, Supercheap Auto has the right fuel additives to meet your needs. Our products work with a wide range of vehicle makes and models, ensuring compatibility and ease of use. With our commitment to quality and reliability, you can trust Supercheap Auto with fuel additives.

Fuel additives are chemicals added to the fuel tank or fuel system to improve its quality, clean engine parts, and optimise combustion. These additives contain detergents, lubricants, corrosion inhibitors, and other active ingredients to address issues like carbon buildup, fuel system deposits, and injector fouling. By tackling these problems, fuel additives can enhance fuel economy, restore engine performance, and lower emissions.

Fuel additives, such as petrol injector cleaner, are vital for keeping your engine healthy and efficient. Over time, carbon deposits, varnish, and sulphur buildup can gather in the fuel system and on engine parts, causing issues like reduced fuel economy, rough idling, engine knocking, and higher emissions. Additives prevent and remove these deposits, ensuring a clean fuel system, better fuel combustion, and longer-lasting engine components.

At Supercheap Auto, we understand the importance of quality and reliability when it comes to maintaining your vehicle. That's why we only offer fuel additives from trusted brands known for performance and effectiveness. With our comprehensive range and expert guidance, you can trust us to help you get the most out of your vehicle’s engine. Shop fuel additives online or visit your local Supercheap Auto store for further guidance.

Frequently Asked Questions - Fuel Additives

Can fuel additives harm my engine or fuel system?

When used correctly, fuel additives are usually safe for engines and fuel systems. However, it's essential to select additives from trusted brands and adhere to the manufacturer's instructions regarding dosage and application. Overusing additives or mixing incompatible products could damage engine parts or hinder fuel system performance. Consulting your vehicle's manual is wise if you're unsure about using fuel additives.

How often should I use fuel additives in my vehicle?

How often you use fuel additives depends on factors like how old your vehicle is, how you drive, the quality of fuel you use, and your service history. Usually, using a fuel system or injector cleaner at every oil change can keep your fuel system and engine in top shape. However, if your vehicle has a lot of buildup or performance problems, you might need to use these more often at first. Make sure to check the product label for exact instructions and recommendations from the manufacturer.
