Bacterial contamination is a major problem in diesel fuel...

The stuff's been around since '07 and got API certification in
'09.  What do you suppose is the sustainable rate of beef tallow
production, and how will that affect what's being done with the
tallow now (frying oil, I suspect)?

The example of PB Blaster shows that just because the can is nasty,
the stuff inside isn't *necessarily* bad...

Did you read the paper on Canola oil synthetic?  They were pretty
proud of its performance...
