Very good Bruce. This is a problem that many of us aftermarket turbo folk have. As I was reading your explanation it reminded me of something my dad did many years ago. We did a lot of boating with two stroke outboard motors and therefore mixed a lot of oil in with the fuel. My father would always buy off the shelf motor oil for the purpose even though his buddies would spend twice as much on "two stroke oil". He maintained that if you read the label and it stated that it was refined from "paraffin based" crude that it would burn clean (like a candle). I didn't question it at the time but it seemed to work just fine. Maybe it would work equally well for our oil burning turbo cars now? I'm off to read some labels.....
