I have read this before and it looks like it works, but I don't have crazy high oil consumption, at least I don't think so. I only use about 1 liter per 5000 miles. I'm hoping it would help with lowered compression. I'm going to try the oil in the cylinder trick to see if it brings the compression up. If it does, then this process will be next.

Awesome pics, awesome situation for those pics too.

My only concern with following this method is that you run the engine for four hours (half a day?). The instructions call for it to be run 10 to 30 minutes. Running it longer makes me nervous that running oil that has been thinned out by the BPR for too long, creating a bigger problem than I already have.
