My engine is rated for B20 so B15 or less doesn't scare me. In the infamous diesel fuel lubricity study a few years ago, B2 created better lubricity than any additive on the market. Supposedly bio burns with less soot, but at low levels it's probably not noticeable. I'm WAY more concerned about getting fresh diesel than avoiding bio-diesel.
