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 on Reviewed in the United Kingdom 17 August 2025* 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. ### ⭐⭐⭐⭐⭐ Seems to work extremely well *by on Reviewed in the United Kingdom 6 April 2025* Arrived quickly from Amazon, we'll packaged. Put this in a full tank on my 2015 1.2 petrol DS3 w/103k on the clock about 2 weeks ago and so far looks good. My fuel gauge is digital and each quarter is split into 3 blocks, since I bought the car 2 1/2yrs ago I've been gauging fuel use by using the trip computer, trip 1 for each block and trip 2 for full tank, each block was going after about 28 miles, 30 at a push, so each quarter tank gave about 84ish miles, so a full tank was returning about 350 miles, my journeys are very much the same month to month, home-work-home, shopping or popping to MILs. Since I've put this in 2 weeks ago each block in the quarter of the fuel guage has been going off after 35 miles, so 105 per quarter so possibly signifying an increase of 70 miles or so for the full tank.Now in February I did have new tyres all round and a wheel alignment so the new fuel economy could be partly down to that but I have felt that the throttle response does feel much better, I've got this on subscription so planning to put this in my car and the wife's every other month and see how it goes but at first impressions it looks to be doing something positive ### ⭐⭐⭐⭐ Crisper engine response & increase in power. *by on Reviewed in the United Kingdom 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.I'd have given it a 5 Star rating if it was around the £8.00 GBP mark ## Frequently Bought Together - STP Ultra 5 in 1 Petrol System Cleaner 400ml, Restores Power and Protects your Engine, Enhances Fuel Economy, Mechanical Car Cleaning Products, Concentrated Cleaning Formula, Made in the UK - STP Ultra 5 in 1 Diesel Fuel System Cleaner 400ml , Restores Power and Protects your Engine, Enhances Fuel Economy, Mechanical Car Cleaning Products, Concentrated Cleaning Formula, Made in the UK --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/57355323-ultra-5-in-1](https://www.desertcart.ro/products/57355323-ultra-5-in-1) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-27*
