I am running 100% fileted WMO and it does smoke bad until it warms up. I really want to add an O2 sensor soi can see what I am putting out the tailpipe. Waste transmission fluid has been a mixed bag, I think I get some that has higher synthetic oil and it actually runs worse than the WMO. It's been a busy summer but I hope to be building a reformer for the oil this fall.
