Not using my bike so often in the winter months the fuel system can 'tar up' with modern unleaded sitting about in it. Carb or injection it's the same problem, I keep a rich mix of Wynns in the tank, personally I put a 325ml bottle in with 15 litres and I've never had a problem. I use it in my Proton Jumbuck pickup too, again never had a problem with the fuel system. Been using Wyyns products for 40 years, on the drag strip in the 70's and in auto boxes etc. ever since. I also run their 'Dry Fuel additive' now and again, can't praise Wyyns products enough.

It does what it says, excellent value for money, a bit disappointed because I thought it would do both petrol and diesel engines, but maybe it was my mistake because maybe I didn't read the specs properly before ordering, unfortunately I have no petrol cars or vans. I only have diesels.

I honestly think you use it as a prevention,not as a cure for some problems so definitely good value,it's the first time I've used petrol cleaner but I'm a good customer for their diesel cleaner,I've used it over and over and I would like to think it's doing its job well as I've had no problems .

Car runs a lot smoother, more responsive. As of yet have not checked if mpg has been improved. The smoother running and more responsive improvement is good, the car is17 yrs old.

I use this each year prior the MOT, always passed the emissions test, so I assume it works?.
