Don’t put clean oil in a dirty engine !

To prolong the life of your engine, it is recommended to change the oil every 5,000 to 10,000 km. In order to prevent contamination of fresh oil by residues left behind, you should clean your engine with an Engine Flush before changing the oil.

What our clients say

I used this in my brothers diesel van as it had a flat spot on acceleration, and the flat stop is clearing steadily. We have used Wynn's product's for many years because they do the job.. I would recommend this.

Bryan P.

This is the first time I used this, it is brilliant. As soon as I put it in, the car was more quiet and is running real smooth.. I would recommend this to fellow drivers.

Actual Ace

Used this stuff since the late 1970's, it does what it says.

Have used Wynn’s products for over 40 years and have never had any problems. I would also recommend the oil additive which I have also used many times.

Water in a diesel fuel tank can enter via the pump or by condensation. Either way, in very cold weather this water can freeze in the fuel filter. This means your engine may not start.... Not good up in a mountain ! This stuff chemically removes the water allowing to pass through the filter, to be burnt in the engine. Good stuff.

I find it really makes a big difference to how my 2006 sprinter van runs. Loads more power and it sounds smoother and quieter and way less smoke from the exhaust system (pretty much zero!), it’s really good and well worth it. Will keep using this indefinitely.
