I’m happy with this product. Not afraid to use engine flush anymore after I watched the fcpeuro video.

I highly recommend this flush it absolutely surprised me how much it cleaned my engine. There is a notable difference in performance. Very happy with this purchase worth every penny. I took 7 days with free shipping over new years week.

very easy to use

I've been using Liqui Moly products for about 4+ yrs. This flush is great on my e46. I use it every other oil change & like how it gets out the bad sludge if any. Great quick shipping.

I'm only giving this product 3 stars as my way of saying that I am neutral. I have no way of knowing if this stuff really works or not, but I thought I would give it a shot at my last oil change.

Bought one for the wife's Hyundai after I saw what came out of my V70! After the Ceratech, the car seemed to run smoother.

I was very skeptical about using this but decided to bit the bullet and try it anyways. I purchased a used MK5 Jetta for a winter daily with around 145K miles. I was unsure of how well the previous owner maintained it so I wanted to make sure I did my best to get everything up to snuff. I couldn't believe how dark the oil that came out was (it didn't look that dirty on the dipstick) I can say 5000 miles later that the new oil i put in is still as clean as when i poured it in so the engine flush must have cleaned it really well!

Use during every major service.

This product does what is supposed to do. Engine is as smooth as ever now. My e350 got 55K miles and this is second time I used engine flush, and noticed engine Oil color change, oil did come out very black/brown but that's normal.
