Better than I ever thought was possible. Bike runs like brand new. The tank was drained first and it was ok. After adding Wynns it has never run better and the difference was obvious after just a couple of miles.

Pro.: Brilliant product. It is essential for my vehicles to run properly in winter weather. Con.: Although the bottle neck is narrow it is still to wide to open filler neck flap and some always spills from the filler neck.

Persistent "water in fuel" waring for a couple of months. 2 days after adding this the warning no longer showed and hasn't returned a week later. Very good result.

Put into our diesel tank after what seemed was a bad batch of branded fuel, our car was jerky under acceleration, since adding one bottle of this to 35 litres of diesel and driving 60 miles problem solved.
