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? ## Features - Cleans the Entire Fuel System in one tank - Removes deposits from Injectors, Valves and Combustion Chambers - Prevents hesitation and power loss - Reduces Corrosion and Prevents Filter Blocking - Saves fuel ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00A0JJI4K | | Best Sellers Rank | 35,129 in Automotive (See Top 100 in Automotive) 245 in Fuel Systems | | Brand Name | STP | | Contains Liquid Contents | Yes | | Customer Reviews | 4.5 4.5 out of 5 stars (153) 4.5 out of 5 stars | | Global Trade Identification Number | 05020144800873 | | Included Components | 1 bottle | | Item Form | Liquid | | Item Type Name | Car System Cleaner | | Item Volume | 400 Millilitres | | Item Weight | 380 Grams | | Manufacturer | Armored Auto Group Sales Inc. | | Material Features | concentrated cleaning power | | Material Type Free | No_Material_Type_Free | | Model Number | GST65400EN | | Number Of Items | 1 | | Part Number | GST65400EN | | Scent | Unscented | | Size | 400 ml (Pack of 1) | | Special Features | diesel fuel system cleaner | | Specific Uses For Product | Engine | | Surface Recommendation | Metal | | Unit Count | 400.0 millilitre | ## Product Details - **Brand:** STP - **Item form:** Liquid - **Item volume:** 400 Millilitres - **Material Type Free:** No_Material_Type_Free - **Material feature:** concentrated cleaning power - **Scent:** Unscented - **Special feature:** diesel fuel system cleaner - **Specific uses for product:** Engine - **Surface recommendation:** Metal - **Unit count:** 400.0 millilitre ## Images ![STP Diesel Complete Fuel System Cleaner 400 ml - Image 1](https://m.media-amazon.com/images/I/8136i7wHvvL.jpg) ![STP Diesel Complete Fuel System Cleaner 400 ml - Image 2](https://m.media-amazon.com/images/I/91svHVQr0qL.jpg) ## Available Options This product comes in different **Pattern Name, Style Name** options. ## Questions & Answers **Q: Hi, I know this has been asked already but is this safe to use on a motorbike?** A: Hi yes. I use it on my old Norton. Works wonders but don't use the whole bottle **Q: Will this restore old petroleum in my boat fuel tank** A: Don't know about boat, but my husband said it was great in the car. Hope this helps a bit **Q: Can I use both the 5 in 1 cleaner and injection cleaner in one full tank?** A: You could but I wouldn't. Both products have properties that help clean various parts from the Fuel Tank to the Combustion chamber. In fact the description of both products show 1-2 identical properties. Just use one and then the other after doing a the guide line of 3-4 thousand miles. **Q: Can this go in a 4 stroke petrol moped?** A: Yes no problem ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect. Stopped my car from shaking at start-up *by on Reviewed in the United Kingdom 7 April 2023* My BMW (12 years old with 113k milage) started to shake when I’d start it up. It used to feel like it was going to take off but the shaking would only last for about 15 seconds or so. I thought it’d be an expensive fix but came across this and thought I’d give it a try. Filled up a full tank of Diesel and then poured the entire contents of this bottle in immediately after. I didn’t notice much difference whilst driving like some people say (I didn’t have any performance issues anyway). However, the shaking at start-up has finally stopped!It’s recommended to use this product every 4000 miles so I’ll definitely be doing that as it has certainly helped with the shaking issue. I’d recommend this. ### ⭐⭐⭐⭐⭐ Fuel system *by on Reviewed in the United Kingdom 2 May 2026* All good ### ⭐⭐⭐⭐ I might buy it again *by on Reviewed in the United Kingdom 18 July 2014* I normally use another product which is readily available at supermarket garages, but I thought I'd give this a go. Much more expensive but apparently it is meant to last much longer rather than using half a bottle of that other stuff each time I fill up.Overall I do think it did a good job but I don't think I would buy it again in a hurry. ## Frequently Bought Together - STP Diesel Complete Fuel System Cleaner 400 ml - STP Diesel Particulate Filter Cleaner 200 ml, Cleans and Protects Your Filter by Removing Soot in One Treatment, Restores Power and Acceleration, Mechanical Car Cleaning Products, Made in the UK - STP GST59200EN Diesel Injector Cleaner 200 ml,Packaging/label may vary --- ## 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.hr/products/51559784-stp-diesel-complete-fuel-system-cleaner-400-ml](https://www.desertcart.hr/products/51559784-stp-diesel-complete-fuel-system-cleaner-400-ml) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-06*
