    Highly recommend this engine flush

    The top of the can has a plastic easy flow neck which makes it really easy to pour into the engine without a mess , unlike the other brands that have a metal ring pull

    Average Product

    Does not provide the same level of piston ring cleaning and added compression that Forte does. I have tried all flushes and this I really would leave on the shelf. Sure it will clean deposits and better to use than not at all. Remember boys and girls always flush and change oil at maximum of 10k particular on Diesel motors.

    Moly engine cleaner is a must before an oil change, gives the engine a chance to recover from an oil with 20,000 miles on it Audi V6 Tdi engine has a lot going on inside it needs the timing chain cleaned an well lubricated to keep thing going nicely
