Trusted by thousands with a 4.5-star rating, it offers a simple, effective solution for maintaining optimal diesel engine performance. ## 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: Perfect. Stopped my car from shaking at start-up - 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. Review: Fuel system - All good ## Features - May be fatal if swallowed and enters airways. - Repeated exposure may cause skin dryness or cracking. - car parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A0JJI4K | | Best Sellers Rank | 77,715 in Automotive ( See Top 100 in Automotive ) 362 in Fuel Systems | | Brand | STP | | Brand Name | STP | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.5 out of 5 stars 151 Reviews | | 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 | | Item form | Liquid | | Item volume | 400 Millilitres | | Manufacturer | Armored Auto Group Sales Inc. | | Material Features | concentrated cleaning power | | Material Type Free | No_Material_Type_Free | | Material feature | concentrated cleaning power | | 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 | | 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 ![Diesel Complete Fuel System Cleaner 400 ml - Image 1](https://m.media-amazon.com/images/I/8136i7wHvvL.jpg) ![Diesel Complete Fuel System Cleaner 400 ml - Image 2](https://m.media-amazon.com/images/I/91svHVQr0qL.jpg) ## 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 S***A on 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.

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.ph/products/51559784-diesel-complete-fuel-system-cleaner-400-ml](https://www.desertcart.ph/products/51559784-diesel-complete-fuel-system-cleaner-400-ml) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-30*
