STP Petrol Treatment (200 ml)

ok

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.

Super Bien. Tengo una Renault Express y he usado diferentes productos al respecto, y al usar éste tengo la sensación de que va mejor, el arranque en frío ha mejorado. Al menos en mi vehículo he notado esos efectos. Muy contento y recomendable su compra

An amazing product gives power to the vehicle, plus fuel savings

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.
