Wynns Engine Flush 425Ml

Love this stuff. Been using it since I had my first car in 1976 and it does what it says. The engine sounds quiter as well as cutting down on any smoke. Just runs smoother, and believe me, I've had some bangers over the years. Swear buy it.

not sure whether this works or not, how do you tell?

car seems to run smoother, could be wishful thinking though...........

Having recently picked up a car I decide despite some good history of oil changes to run a tin of this through the engine and then perform a normal oil change.

Instructions are simple run the engine up to normal operating temperatures and then add the solution. Idle the car for 20 minutes and then do the normal oil/filter change. Don't skimp the filter part because this is where any bits that are removed will end up whilst it's normal procedure to change the filter with the oil I've seen people...
