I can get plenty of Google hits for people saying that short OCI (1-2K) with high quality oil will clean out engine sludge, but not many before and after images or videos. There are some videos of guys using additives and showing the cleaning progress, which actually performs better than I would have thought. Anyone have any links to posts or videos with actual before, during, after samples of just using straight oil and no additives?
My 2002 Toyota van with the infamous 3.0 V6 sludge monster, was driven and maintained by the same family since new, but their daughter used it for college, and judging by the coolant, shocks, and tires, she wasn't too keen on maintenance! (plus the thing smelled like sweaty stripper perfume for a month after I got it. LOL)
The van runs great, so even if doing short OCI doesn't clean it up all the way, it should be OK as long as it doesn't increase the sludge.
So far it has seen 3 oil changes since July. It has Mobil 1 HM FS 5w-30 in there now with a Denso yzzd1 filter. First two were with Pennzoil Ultra Platinum FS which caused oil to leak onto the ground daily, clearly cleaning some sludge out of somewhere?
