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.
