It prevents buildup of harmful deposits, reduces emissions, fights rust and corrosion, and improves fuel efficiency. Trusted by professionals and enthusiasts alike, it helps maintain engine responsiveness and reliability, making it essential for modern long-life servicing intervals. ## 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: STP ST51200EN Petrol Treatment, 200 ml - I have a 53 plate 1.8 astra coupe with 103000 miles on it that on the whole runs fairly well and seems to have been well cared for mechanically over the years, it generally gives around 350-370miles (maybe even a little more on long slow motorway runs). Recently it has been feeling a little less responsive, nothing major but equally noticable, it felt like I was having to work the car a little more than normal so I thought as it is over 100000 miles it couldnt hurt to give this kind of product a try. After the first full tank (with the cleaner in) It did feel like it's less hesitant and a little more eager to pull at low revs in high gears, again, nothing really impressive but it definitely improved things a little. I will also add that it achieved 365miles from the tank and I didnt feel like I had worked that hard to achieve it, so it would seem that while it didnt massively improve my economy it did make it easier to achieve good mpg and I am curious how it will do with a long economic run. In sumary, I think the best approach to have when using this stuff is not to expect mirracles, you may use this and get lucky, your car may be heavily fouled up and you will see much better results than I did or the problem you have could be a lot more major and mechanically based than a bit of fouling of injectors etc - I thought it was worth a try as my car was just a little sluggish and I am very hapy with the result, to the degree that I am contemplating using it in my other (much better) car because it sees to have helped this car. Review: Solves water/condensation issue - That's exactly what I bought it for, since I understand it claims to do this. More specifically, I bought a 2nd hand car and learned from the previous owner that it usually ran on a petrol tank with few gallons. I suspected this caused condensation in the gas tank (droplets of water), which of course does not mix with petrol. I wanted to get any water out of the gas tank or the fuel system. The car was not running very well, although the fuel injects were new, so after using this product the first time, the engine started running smoothly. I could be wrong, but I believe the product got rid of the water that I suppose had contaminated the gas tank/fuel system. Anyway, great price, great product, as I expected from STP. ## Features - Harmful to aquatic life with long lasting effects. - May be fatal if swallowed and enters airways. - Repeated exposure may cause skin dryness or cracking. - STP Petrol Treatment 200ml, to keep your fuel system clean - Prevents Deposits: Helps stop the build-up of harmful dirt, gum and deposits in the fuel system - Reduces Emissions: This fuel system cleaner helps reduce exhaust emissions - Saves Fuel: Fewer deposits helps you make the most of every gallon - Fights Rust: This petrol system cleaner fight rust and corrosion in the fuel system ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0095KMPJK | | Best Sellers Rank | 190 in Automotive ( See Top 100 in Automotive ) 10 in Fuel Systems | | Brand | STP | | Brand Name | STP | | Contains Liquid Contents? | Yes | | Contains liquid contents | Yes | | Country of Origin | United Kingdom | | Customer Reviews | 4.5 out of 5 stars 339 Reviews | | Global Trade Identification Number | 05020144800514 | | Included Components | Petrol Treatment | | Item Type Name | Petrol Treatment | | Item Volume | 200 Millilitres | | Item Weight | 225 Grams | | Item volume | 200 Millilitres | | Item weight | 225 Grams | | Manufacturer | STP | | Model Number | GST51200EN | | Number of Items | 1 | | Number of items | 1 | | Part Number | GST51200EN | | Size | 200 ML | | Unit Count | 1 1 | | Unit count | 1 1 | ## Product Details - **Brand:** STP - **Contains liquid contents:** Yes - **Global Trade Identification Number:** 05020144800514 - **Item volume:** 200 Millilitres - **Item weight:** 225 Grams - **Manufacturer:** STP - **Number of items:** 1 - **Size:** 200 ML - **Unit count:** 1 1 ## Images ![Petrol Treatment - Image 1](https://m.media-amazon.com/images/I/61AAYs5GuOL.jpg) ![Petrol Treatment - Image 2](https://m.media-amazon.com/images/I/71+PfeG90JL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: I have just put this in my diesel car.Will it be a problem?** A: don.t put petrol cleaner in a diesle car, i put it in my petrol car and did make a difference hope this helps **Q: Do you run engine after you put bottle in to let it pass through to carburettor** A: You don't have to run the engine to flush it through, because you add it to the petrol tank and it works when you drive. **Q: Is this an octane booster?** A: No **Q: Can I use this in a petrol lawnmower?** A: I do not see why you cannot, but for what benefit?, I doubt it would cure any running issues, it basically increases the octane level of the fuel and would clean out and deposits over a period of time. If you have running issues I would strip down the carburettor first and clean and replace any parts needed. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ STP ST51200EN Petrol Treatment, 200 ml *by C***S on 30 January 2017* I have a 53 plate 1.8 astra coupe with 103000 miles on it that on the whole runs fairly well and seems to have been well cared for mechanically over the years, it generally gives around 350-370miles (maybe even a little more on long slow motorway runs).
