I'm doing it, I think I recognize your screen name from oil burners. I'm JPhauler over there. My Cummins loves it, so here I am.

Just got the car, 86 300SDL. Probably have about 100 miles on it running my WMO blend. So far, excellent. Starts at 10* as soon as you touch the key. Very light haze at idle. No real noticeable difference in power. I'll report back after I get some more miles on it running the blend.
