Wynn's Petrol Injector Cleaner - Reduces Fuel Usage & Emissions - 325ml

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

My car has been misfiring and running quite rough for a few months now so I decided to give this a try before forking out for new fuel injectors. I was sceptical, but I was sold by all the positive reviews. I didn't notice much difference on the first day after using this, but then I came to use my car the next day and the difference was incredible! No misfire, the engine was the quietest it has been all year and the performance is significantly better too. I'm not sure if this will be a long term solution, but this gets a high recommendation for me.

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.

Use this regularly for our older cars. My wife's 2001, 80k mile, Shogun, GDI 3.5 and my 82k mile Jaguar X-type 3.0 petrol 2003. The former does dozens of short trips each week on a care round so the engine is prone to clogging up at fuel intake (recently cleaned). My Jag does longer trips and after adding this stuff and using proper high grade fuel it runs like a new car floating along the motorway and other roads. Eliminated all traces of a misfire I had on purchase, and mpg shot up (albeit it is low). I cannot prove this is the only reason for improvement but older injection cars do need something every few months. Make sure you follow instructions and have at least 20 litres of petrol in the tank first and not let the seal into the tank! or the cleaner effect is wasted.

I used to use RedX bought from ASDA and didn't really see a change in anything, so I did some research on YouTube and came across this. I've used it in a Nissan Almera 2006 with close to a full tank and drove from South Wales to Oxford and back. Have I seen a change in performance? Well, it's early days, but some say over 500 miles to notice a change, so we shall see... I'll keep using it for as long I have the car, as it costs less than a pint of lager...

I've had problems with my Renault Twingo's engine lately (irregular idle speed + problems to start) and decided to give Wynn's injector cleaner a go before spending a lot on spare parts. I was actually quite sceptical at first but thought that after 130.000 miles it couldn't do any harm to the engine. So I went to a petrol station, poured the whole can contents into the tank and filled in with petrol (My tank is about 45 litres). I left the petriol station and started driving on the bypass and wow, I was really surprised how quickly I could notice the difference especially in terms of torque. Because my injectors were getting old and must habe been blocked in some way, the difference was really noticeable. The car didn't gain power or anything but it simply went back to how it used to work when I bought it 7 years ago..It's really funny how progressive the loss of torque can happen on an engine and how we get used to it. So to conclude, I'm very impressed with this product and will definitely use it again when my car reaches 260.000 miles :-)

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

After using this product just once there was a marked improvement in fuel consumption

I use this every 10k kilometres. Seems to work

Aucun problème,super

It works

El coche pegaba unos pequeños tirones y sospechaba que eran los ok inyectores y después de usar este producto dejo de dar tirones , no es un arreglo definitivo pero para al menos ahorrar para cambiar los inyectores te da

شكرا جزيلا
