How can I improve engine performance?

All engines naturally suffer from a build-up of carbon over time due in part to the varying quality of the fuel available at the pump. Unfortunately this can lead to problems with fuel efficiency and increased emissions. Even the smallest amount of carbon build up on fuel injectors, intake valves and combustion chambers can affect engine performance. We sell a range of products that are specially created to clean, lubricate and protect your engine & fuel systems and can help prevent the build-up of unwanted deposits when used in conjunction with an oil change or regular servicing. We stock a range of Cataclean treatment products that are available for both petrol and diesel engines.

Cataclean Products


Fuel System Cleaner

Our Fuel System Cleaner restores fuel delivery performance in your engine and reduces harmful exhaust emissions by up to 60%. Available in specifically designed formulas for petrol and diesel engines, both contain high quality detergents and additives that are poured directly into the fuel tank to restore performance and MPG, eradicating deposits in combustion chambers and restoring flow in fuel injectors. Basically, cleaning the entire fuel system! Fuel system cleaners can be purchased online with any tyre fitting, MOT or Service booking.


Engine Flush

Our Engine Flush oil system cleaner provides an oil supplement to replenish and fortify critical oil additives, reducing wear on engine parts and increasing engine power and performance. Engine Flush is suitable for both petrol and diesel engines and can be ordered when booking a service – we’ll add the treatment while carrying out your oil change. One treatment can help remove sludge, dirt and varnish left in the engine and prevents contamination of the new oil.
