Engine & Fuel System Treatments

At Formula One Autocentres, we believe in helping your engine run cleaner, stronger and more efficiently. That’s why, when you book tyres, an MOT or a service online, you can now add our specially selected engine treatment additives as an optional extra, it’s a simple enhancement that can deliver noticeable benefits.

Why consider an engine treatment?

Cleaner fuel and intake systems
Over time, deposits build up in injectors, intake valves, and combustion chambers. A quality additive helps break those down and keep your engine running smoothly.
Reduced emissions
By cleaning carbon build-up and improving combustion, you help your car emit fewer pollutants.
Better fuel efficiency
Smoother fuel flow and improved combustion can contribute to modest gains in mpg.
Enhanced engine response
Many drivers report crisper throttle response, smoother idling and fewer misfires after using an engine treatment.

Our selection of treatments

We stock high-quality products designed for both petrol and diesel engines. Some target overall fuel and combustion system health, while others focus specifically on injectors, intake valves or exhaust control systems.

Each product is selected for reliability and proven performance, so you can trust it complements your service without risk.

When to use a treatment

We recommend using an engine or fuel system additive:

At every major service (or every 10,000-12,000 miles)
Before a long trip to improve performance
If you’ve been doing a lot of short journeys (which tend to cause deposit build up)

How to add a treatment with your booking
