Trusted by thousands with a 4.6-star rating, it’s an easy, cost-effective way to maintain your vehicle’s fuel system between services. ## Description From the manufacturer STP = Scientifically Treated Petroleum Build up - Intake Valves Deposits on the intake valves can restrict or change the flow of air/fuel mixture into the combustion chamber When you shut off the engine, fuel that remains on the intake valves can polymerize into a hard carbon deposit or form a sticky gum Oil leaks past the valves seals and can contribute to deposits on the back of the intake valves Exhaust gas recirculation, which is a mechanism used in engines to reduce emissions, can cause soot and other combustion by-products to deposit onto the valves Fuel Additives For over 60 years, and for more miles than anyone can count, STP has been one of the most trusted names in automotive care. Car enthusiasts, “Do-it-Yourselfers” and professional racers rely on STP oil additives, fuel additives and brake and power steering fluids to keep their vehicles running better longer Due to 'Long Life' servicing intervals being stretched further, many vehicles face a build up of deposits that could have major implications on engine performance So why Use a Fuel additive? Additives are a relevant part of engine maintenance regime Car manufacturers recognise that “Clean engines = Better performance” Additives help keep vehicles running well, extends reliability, less likely to break down Build up of carbon deposits can occur within 4,000 miles, no matter how new or old the car is Build up - Injector Cleaners Clean fuel injectors are critical to vehicle performance Deposits can affect spray pattern and flow rate The spray pattern of fuel affects air/fuel mixing Fuel may be in droplets that don’t evaporate Fuel may stick to the intake port and not be drawn into the combustion chamber Clogging affects amount of fuel delivered, which results in inaccurate air/fuel blend Review: Good petrol system cleaner - I tried the STP Ultra 5 in 1 Petrol System Cleaner and I am really impressed with the results. I added the 400ml bottle to a full tank as recommended, and after just a few drives I could feel the difference. The engine runs smoother, the idle feels more stable, and acceleration is noticeably more responsive. It also seems to have reduced a bit of hesitation when pulling away. Fuel economy has slightly improved as well – not a massive change, but enough to notice over a couple of tanks. What I like is that it’s a concentrated formula, so one bottle is enough for a full treatment. It gives peace of mind knowing it’s helping to clean injectors, reduce carbon deposits, and protect the fuel system at the same time. Easy to use, good instructions on the bottle, and made in the UK which is a bonus. For the price, I think it’s excellent value – cheaper than a garage clean and helps keep the car maintained between services. Review: Does what it says on the bottle - Easy to use, saw improvement between last tank and end of this tank in acceleration and responsiveness.

How much of this 400 ml bottle should I put in?** A: Half should be sufficient for that tank.it wont hurt just increases strength of you use more. **Q: Can this be used on modern car engines. my mb vito 2015, diesel states no addeditive should be added to the fuel. some say it may damage the cat?** A: If your user manual or manufacturer literature states that no additives should be used, then I would follow that directive. However, it is something that you might want to check with the manufacturer. If you use fuel from a recognised oil company, like shell or BP etc. you don’t need to use this cleaner as the additives are already in your fuel. If you use supermarket fuel like Asda or Sainsburys, then you would want to use an additive, but like I said, check with your manufacturer first. **Q: I bought a set with diesel treatment. can i use them both at the same time?** A: I would use one at a time just follow the instructions. **Q: How does the MPG gains maintain for the full 4000 miles before the recommended time to add a new bottle to it?** A: I renew after approx. 3500 miles and am satisfied with the MPG since I have been using the product. An approx. gain of 3/4 MPG. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good petrol system cleaner *by E***S on 17 August 2025* I tried the STP Ultra 5 in 1 Petrol System Cleaner and I am really impressed with the results.

Improved petrol mileage too ### ⭐⭐⭐⭐ Crisper engine response & increase in power. *by L***M on 1 May 2026* I use this product a lot for my various cars, especially if they are not being used too often. and will double dose if a car will be stood for a month or so. I find it really works, providing crisper engine response, slightly increase power / performance - acceleration and better engine idling and at all rev's - speeds.
