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!
