Super product

I swear by this product. I use it before every oil change. It gives the engine an excellent clean out of all its gunk and residue, and makes the oil thinner in viscosity so it is easier to drain. It is also very easy to use, just warm the engine pour in the product and let it do its work for 20mins. You can't go wrong at this price, highly recommended.Read full review...

Great Tonic

Thought that I would try this instead of my usual Tonic with gin bit thick but once mixed well tastes great next time I will try with fruit

My thoughts

I popped the can into my 08 MINI R56 with 118,000 miles and the car did hesitate once or twice at idle but afterwards my lifters stopped tapping with the oiled changed after the car seems smoother and quieter. Overall I'd definitely use this product againRead full review...

Wynns Engine Flush

I have been using this product for about 5 years,to me it makes sense.Engines are by nature very dirty and require a good product (wynns engine flush)to ensure a clean engine before changing oil filter .Read full review...

Cured my starter problem.

Wish I'd done an engine flush earlier! Starter clutch in my FJ1200 bike not engaging any more. I followed the instructions and the problem was cured! Now I don't have take the engine out and split the cases. Not only that, the engine runs like it is ten years younger. Gear changes are sweet. no more searching for neutral; plops straight in.
Amazing amount of crud in the flushed oil. Bike's happy and I'm happy!
I'll be doing my ZRX1200 next.Read full review...
