I was just curious because it seems that there are plenty of SVO naysayers, but each of them seems to advocate the use of Bio-Diesel, so I was wondering if anyone refuses to use bio for whatever reason, assuming ambient temperatures stay above the gel point. And this is transesterified VO, methyl or ethyl esters, bio-diesel, none of this "diesel secret" garbage.

I would, but I want to get my tank cleaned and be prepared to replace any leaky fuel lines/replace them preemptively before I do.
