I am not certain that this works wit no faults, but as of now, my oil analysis has come back great and in the top 2% of similar tested results at Blackstone Labs. If nothing else, its good peace of mind.

Worked as advertised. Use about a half quart less oil than recommended capacity to account for the additive.

Good product

First time using these Liqui Moly additives and I would definitely buy this combo after a few oil changes. Car runs great.

Love Liqui Moly!

Probably should have used 2-3 of these but its nice and easy to do

Once I bought and gad used these, I later read that I didnt have enough of these items. Honestly I did see a bunch pf sludge come out with my oil AND I had slight lifter tick and after the oil change and the ceratec it went away.

My '06 530i has over 165k miles and I used this additive kit. I do my own oil changes so I saw the gunk that came out of my engine after using the engine flush! My engine sounded so much smoother after the oil change additive package. I just recently did an oil change prematurely after 3k miles of adding the oil change package. And when I drained the oil, I could still see the Ceratec additive in the oil! If you have a European car and don't use this to help possibly extend your engine life, you are doing your car, your self and your wallet a disservice. Get you some!!!

I use the engine flush every other oil change to get as much contaminants out of my engine before and oil change, it drains out all the oil super quick. I use ceratec every oil change, just as a piece of mind and it even got rid of my lifter tick in my 335i engine. I also love the little sticker it comes with so I can keep track of my mileage. Great products!

Recently purchased 2014 Jetta TDI, love the Liqui Moly products and thought I would use this for the first DIY oil change.
