When should I use a fuel system cleaner?
Wondering how to know if your fuel system needs cleaning? It’s recommended that motorists use fuel system cleaner every 3,000 to 5,000 miles as a preventative measure, to avoid problems further down the line. However, if you notice any of the following signs, you might want to consider giving your fuel system a clean straight away:
- Poorer fuel economy
- ‘Rough idling’ (an engine that doesn’t run smoothly)
- Lower engine performance or throttle response
- Sputtering engine
- Greater emissions levels
Who can use fuel system cleaner?
Fuel system cleaners like Cataclean can be used for both diesel and petrol cars. Cataclean has universal compatibility, allowing it to be used with hybrid engines too. For diesel engines especially, fuel system cleaners can be highly beneficial, as DPFs (Diesel Particulate Filters) can often get clogged when catching particulate matter. Products like Cataclean can help with this issue.
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 and fuel systems, and can help prevent the build-up of unwanted deposits - particularly when used in conjunction with an oil change or regular servicing.
Fuel system cleaner
Our fuel & exhaust system cleaner restores fuel delivery performance in your engine and reduces harmful exhaust gas 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. This works 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.

Engine performance FAQs
Got a question about your engine’s performance and health? Find the answer below. If you can’t find the advice you’re looking for, get in touch with our team of experts directly.
Do fuel system cleaners actually work?
Yes, fuel additives like system cleaners work well and can have significant benefits for your car’s engine and emissions levels. Fuel system cleaners like Cataclean work at their best when used regularly (every 3,000 - 5,000 miles) and as per the instructions.
Can I put fuel system cleaner in a full tank?
While you can add fuel system cleaner to a full tank of petrol or diesel, it’s not recommended. Cataclean recommends using a quarter of a tank of fuel for ease.
Is it good to put fuel system cleaner in your car?
Yes, there are multiple benefits when it comes to using fuel system cleaner. You’ll notice fewer emissions, greater engine performance, and even better MPG (miles per gallon) and fuel economy.
How long does it take for a fuel system cleaner to work?
When using a fuel system cleaner like Cataclean, it’s recommended that drivers add the necessary dosage of cleaner to a quarter of a tank’s worth of fuel and drive 15 minutes. However, it can take a few hundred miles before the restorative effects of a fuel system cleaner become noticeable.
Can I clean my fuel system myself?
Yes, you can clean your fuel system yourself by using a fuel system cleaner like Cataclean, which also cleans the following: fuel tank and lines, fuel injectors, combustion chamber, intake valves, oxygen sensors, EGR valves, catalytic converter, and PPF/DPFs.
What are the symptoms of dirty fuel?
“Dirty fuel” refers to petrol or diesel that’s been contaminated with debris, impurities, dust, or water. Dirty fuel can cause the following symptoms:
- Engine performance issues
- Check Engine light turning on
- Reduced fuel economy
- Loss of engine power
- Rough idle
- Sputtering engine
- Engine misfiring.
If you encounter any of the above, speak to the experts at Kwik Fit — you may need an engine system clean.
How many bottles of the fuel system cleaner should I use?
The amount of fuel system cleaner you need depends on the amount of fuel in your tank. Here’s Cataclean’s official guidance on ratios and dosage: “Add one 500ml Cataclean treatment to approximately a quarter a tank of fuel (15 Litres), drive the vehicle for approximately 15-20 minutes and refuel when necessary.”
