## 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  on Reviewed in the United Kingdom 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). 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.

### ⭐⭐⭐⭐⭐ Solves water/condensation issue
*by  on Reviewed in the United Kingdom 21 May 2019*

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.

### ⭐⭐⭐⭐ All good
*by  on Reviewed in the United Kingdom 31 May 2018*

Does the job . Only remark . Lid could do with how man ml it holds . Using on bike so smaller fuel tank so guess work
