Wynn's 71867 325ml Dry Fuel

I knew there was water in the fuel system of my classic car, when I took it out of storage. After I drained out all i could without removing the fuel tank, there were still occasional problems of hesitation and loss of power. I half filled the tank with fresh petrol and added the Wynns. I ran the engine on the drive until it warmed up, then took a test drive. The car went like it had suddenly acquired a supercharger and felt twice as powerful as before! There was a little cough after a couple of miles (presumably as it was clearing the contaminated fuel out of the carbs), but the car goes so well now. Highly recommended!

Great product I all ways used this every winter the place I used to buy it from stopped selling it glad I found it here smooths the tick over out on my 4liter van every time you do use a bit more diesel while it goes through the engine but after it pay for it self starts a lot easier to love this stuff.

Seems to have worked on my Peugeot Boxer, I was having trouble after filling up at an out of town petrol station (van kept stopping at traffic lights, etc ) I suspected water contamination. Tried this and after a brief hiccup when the van just stopped for a few seconds driving down the road it's been fine since.So as far as I can see it worked.....and at the price it's worth a shot.

My Jaguar petrol filler cap is mounted vertically to the side of the boot lid. On leaving the car parked for two weeks under a fur tree, the dead leaves (small needles) filled the rain filter. Owing to very heavy rain, the blocked filter caused the rain to accumulate above the filler cap and seep into the tank. I drained the water from the tank at the feed to the engine until the engine started, then I used this product to ensure that no water remained.It didn't affect the engine performance when added to the petrol tank and hopefully will remove any remaining traces of water left.

It was ok but may need to add another in

I had a fuel problem in my old camper van that turned out to be water in the fuel. This was a nightmare, being AA relayed back home spoiling our Easter trip.A garage said I would need the tank draining (£60 of fuel) and the water. Then I was told of this product Wynns Dry Fuel, Right I thought cant see this stuff working but ordered it from Amazon and it was here next day.Added this to the fuel tank and started the camper up and took it up the road, it popping a few times but kept going pretty rough but kept running, after the stuff sloshing around in the tank for a quarter mile the engine started running very smoothly and after 5 miles the problem had gone. Guys I saved £160 plus labor by spending £7.Recommend you get this even for emergency use as filling stations often cause the problem adding water to fuel.One very happy camper.

Had symptoms of power loss while driving on motorway. At first I thought it might be my throttle pedal control unit. I have a BMW that has electronic throttle control. Quite an expensive fix if that goes wrong. But then I thought about condensation and the possibility of water build up in the fuel tank. I had had similar symptoms before in an older car without all the fancy electronics So I gave this product a shot. Why not? It's not going to do any harm. It sorted the problem out. I will now use this once every 12 months as part of my normal preventative maintenance regime.

Did not work
