The detergent worked great on my 1.8T. I couldn’t believe how much of a difference there was in the amount of oil drained.

This is the first time using an oil flush on my new car just to make sure the crank case stays clean and doesn't build up any deposits. It is hard to tell if it did anything or if my oil was already very clean, but no sludge came out which is certainly a plus. Would buy again in the future after a few oil changes.

my car idles and start much quieter now, can't make sure if it was this or the liqui moly 0w-40 oil I changed in, but either way it was a great combination on this oil change

I am a service advisor at a busy shop. We work on all makes and models of vehicles. This product has helped "clean up" many older engines.

Flush your engine, man...it’s easy!

I figured I try this out on my BMW 328i with 130K. I have done my own oil changes and have consistently seen the drain process. After using this I noticed the drain was more of a heavy rapid flow after letting it sit and run for 10 minutes. Not sure if that's what its suppose to do. But I figured with a high mileage car why not give this a shot.

I like to use this every third oil change (15,000 miles) on my 335 with 150,000 miles. Great to use on a high mileage car you purchased when previous owner oil change intervals are unknown. Likely unnecessary if you have a new car and you change your oil regularly.

smells good, but didnt notice anything visually weird or different with the oil.

Does exactly what you want it to, clean out the engine and prevent sludge build-up. I use it once a year and the inside of my engine stays very clean

i used it. not sure it made difference or not.
