I think the general consensus around here is that it is a bad idea. First, there are additives in motor oil that are designed NOT to burn, which is exactly what you do not want. Second, what is the source of the WMO? If from your diesel, then it will be full of soot and other goodies that can cause a lot of wear on the pump and injectors. That being said, there are a few people here that run a small mix of it. If you are going to do it, filter it extremely well first.

Strokes running 100% WMO? Got a link to that? I'd like to know where they are getting enough WMO to run 100%.
