Injector Cleaner

My 650 single cylinder motorcycle wouldn't start after being left sitting too long, even fresh premium fuel with it's detergents didn't help after fully draining the tank... Decided to try this STP injector cleaner in a very concentrated mix (much higher than on the instructions) and after a couple of minutes of intermittent starting the bike fired up and is running perfectly smooth every time.

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.

I recently used the STP Petrol Injector Cleaner in my car, and the difference in performance was noticeable almost immediately. This product is perfect for anyone looking to maintain their vehicle’s engine health and improve fuel efficiency.Performance:After using just one bottle in a full tank, I noticed smoother acceleration and improved throttle response. The engine felt more responsive, and the car idled more smoothly than before. It’s great for cleaning out those hard-to-reach parts of the fuel system that can get clogged over time.Fuel Efficiency:Over the next few fill-ups, I saw a slight improvement in my fuel consumption. While the difference wasn’t huge, every little bit counts, especially with rising fuel prices. This cleaner seems to help maintain the engine’s performance, which in turn keeps fuel efficiency up.Ease of Use:Using this cleaner couldn’t be simpler. Just pour the 200 ml bottle into your fuel tank when it’s full, and let it do the work as you drive. The instructions are clear, and there’s no need for any special tools or equipment. It’s a quick, hassle-free way to keep your fuel injectors clean.

I purchased this item at a great price that arrived promptly which after reading the description, it sounded just what I needed to unblock a sticky fuel injector on my beloved Vauxhall Vectra b Sri 2.0i that was causing a tapping sound on start up, with the EML light intermittently going on and off for many months even after trying several other products.I used the entire bottle after filling up with E10 fuel and miraculously after several days the noise completely disappeared, plus the dashboard light stopped coming on, this stuff is unbelievable and I will continue to put it in my tank every couple of months just as a preventative measure, I highly recommend both this seller and their products, thank you!!

My misfire always showed as soon as the auto-choke went off which screamed partial injector blockage. Added this to a full tank and at 5 miles the difference was becoming apparent but by 20 mike's it was like having a new engine. I presume it wasn't just the one injector though it was obviously the worst if the four. Now they are all cleaner and getting cleaner with every mile. The difference beggars belief.

The tip of the bottle jammed in the anti-theft flap in my car's fuel tank filler neck. I fear I may have damaged the vehicle pulling the bottle out.The car seemed happier for having the additive in, however, but I'm reserving judgement on the effectiveness until it's gone through the whole tank.

Good one

Ok
