A Winner for Engine Health
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

Works amazingly well
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.

Good stuff for older engines at least
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.

Smoother and better response
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.

Fuel cleaner
Bike been splattering a bit. I've used Wynn's before on other bikes and cars and it's been great. Easy to use and bottle small enough to carry on you to garage to fuel up. Not had chance to go on a long ride so will wait and see if anything changes. But I am happy with product and it's a reasonable price for what it is. Worth giving it a go.

Made a significant improvement to my engine
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.
