This is probably better posted in the alternative fuel forum, but it's slow and I'd be preaching to the choir. I'd rather run it by some skeptics.

Anyway, new IP and engine is probably mid life. There's no place to buy biodiesel here in WV, so I was interested in brewing my own and blending with diesel to get B20 or perhaps even B50 in a single tank system and going back to straight diesel or B5 during the winter months.

I understand that the lack of lubricity in modern fuels could cause premature wear on fuel injectors and IPs. So I'd like to explore biodiesel and get some of that back while at the same time, avoiding possible long term damage from straight VO or filtered WVO. Not to mention, I don't want to cut up my car to install a two tank system.
