Works great, do the double drain for best results
My 06 Altima (185k miles) had been burning massive amounts of oil (like 4 quarts every 800 miles) due to a leaking PCV valve hose that took forever for me to narrow down (months). So after getting that under control I figured I needed to decontaminate the poor engine.
When using this I idled my car to operating temp (about 8 minutes). Poured the bottle in, idled it for another 15 minutes. Drained the oil (black and thick). Put the plug back in, poured about 2.5qts of new oil in. Idled it for 10 minutes. Drained that (black but much thinner). Took the old filter off. Let both areas drain for 10 minutes. Put the plug back in, put the new filter on and filled with the 4.6qts of new oil my car calls for. Ran for a few minutes (like 2 with a few revs) and then let sit for 10 mins before checking the level.
When I checked my dipstick it was so clean I thought I had a leak because I couldn't see it on any of the crosshatch. I ended up having to go by touch to get the reading. This stuff is amazing.

Worked for me! Definitely recommend!
Used a whole can in my 2009 Civic 1.8L with 150k miles. I can honestly say, this helped remove a lot of sludge out of the engine. The oil came out with a water-like texture and super dark! Before taking out the oil filter, I added new lower cost oil to the engine and let the engine run for about 5 minutes to get that extra flush! You can definitely see all the extra sludge in the new oil!
Drained and refilled with new oil and filter. The engine definitely sounded quieter and smoother than before!
If you value your car, I would definitely recommend doing this flush on your higher mileage cars every 50k miles or so!
Definitely recommend this LiquiMoly product!

3rd Update! See review... Good stuff and works as advertised...
Update - 3rd oil change/flush. Engine oil draining from engine is waaaay cleaner than my first flush. Probably won't need to do a 4th time for several changes. I added Ceratec at this change and am amazed how much better the engine performs since my initial flush. Less clatter and very smooth idle. (Jeep 4.0 I6)
Update- 2nd change and used the flush again. About 7000 miles from first use. The oil was cleaner and less "gunky" as first time but oil was definitely dirtier than normal. Right away noticed off idle throttle response improved. Then on a drive I take regularly with a mountain pass and long downhill I noticed that even tho the jeep downshifted out of OD it took much less throttle to hold 65 up a long grade. On the downhill normally I would see 50-60 mpg max on the digital readout. This time. It went to 99 which to me indicates more vaccum below the throttle plate. My guess is the rings freed up a bit more than the first flush and highway mileage is up to 23+ where I would get 21 before. Nice!
Used in 2001 Jeep Grand Cherokee. 140k miles and a ticking lifter (common in the 4.0 - 6 cylinder...). Definitely cleaned sludge (oil filter very heavy!) and oil was dark when draining. Idles smoother, oil stays cleaner longer, slight oil pressure increase and runs cooler. The lifter still ticks but probably a cam lobe issue. Will use it after 7500 miles or 1 year. Will report back after next change.
