I think you'll find most people here are relatively well-versed in biodiesel/SVO/blending... they certainly don't need a "primer" on how/why it works.

The issue is about optimistic claims. People new to veggie/biodiesel/blending tend to be enthusiastically optimistic about the benefits and improvements. Sometimes it doesn't stand up to scrutiny.

I'm certainly not a cynic... I've been running WVO for over 5 years.
