I have a guy that i can get a bunch of oil from but he said its a lot of synthetic Harley oil that has a high flash point. Would this affect engine performance when burning? I plan on mixing 80/20 and filtering down to 1-2 mircrons.

 

You might want to post to the Alt Fuels section ( Bio-diesel, Propane & Alternative Diesel Engine Fuels - Ford Truck Enthusiasts Forums ) cuz there are more WMO people there. But from what I remember, synthetic oils were a no-no.

 

Ah, i forgot we had a forum for that. Thanks
