Wynn'sPetrol Injector Cleaner - Restores Spray Pattern - Prevents Deposits, Improves Combustion & Cold Start - Reduces Fuel Consumption & Emissions - 325ml

Worked great. Will definitely use again saw the results very quickly

I cannot believe how well this worked.I was really struggling with poor MPG especially on motorways.Put this into a full tank of fuel and saw an increase the next time I drove.Have subscribed for every 3 months!Fantastic product.

I had originally mis-diagnosed an issue with my car believing it was injector related. This of course was not solved by this product, however it certainly left it with a better throttle response and a slight increase of mpg over time. The car hasn't done that many miles so I would expect an even better effect on a car a little later in it's life. Good product and I'll more than likely put another can through the system in a few months to ensure it continues to run at its best.

Feels like there’s been a massive improvement in fuel consumption

Halved my stupid petrol consumption on Jaguar, Highly Recomend

Our little Fiat Punto had trouble getting thru the last emissions bit of the MOT. I think it was cause the tech forgot to turn the headlights off.....but still it tested ok twice in a row and we passed. But we have been running cheap gas thru the poor car and got me thinking it wouldnt hurt to run the cleaner in a tank of gas and then run Tesco 99 from now on.Caution: do not put this in your tank and try to get tested, the extra cleaners will make the readings all wonky. Run a tank with the cleaner thru the car. Run a whole full tank again thru the car. Then fill up with the best gas you can and go in for your test/retest. Make sure you dont arrive early for your appt. And drive for over 20-30min to make sure the car is good and warm for best emissions results.Our little 1.2 engine has been pulling up hills in 5th gear much better than before. It is also humming along the motorways at a confident speed. We will stick with the 99octane fuel since we have seen a 5% increase in milage and the stuff costs about 5%more ......so its a wash. We are also hoping the better fuel wont clog up the engine. Fingers crossed......The bottle works a treat getting it into the tank, past the tricky 'unleaded' flap of our car. The bottle nozzle is long enough to make it down the fill pipe and you can tap the last bits out and push the last bits into the tank. The bottle is sealed with a sliver sticker over the opening......I would suggest you take it all the way off and dispose. It can pop back into place and stop the flow of cleaner if you just puncture it in. And it could also go into the tank, so just rip the sliver sticker off.Doesnt stink, doesnt do any harm, does have measurable benefits and is easy to use. 5stars

It is fairly cheap but it has improved my partners bike running levels so he is a happy biker!

Worked well , it seemed to do the job as it says on the bottle
