Two Choices: B20 (20% BioD + 80%LSD) or B5 (5% BioD + 95% ULSD)

Yesterday as I filled up with B20 at the one Haycock Petroleum pump in Las Vegas where it is available, I noticed that their B20 is a blend of 20% BioDiesel and 80% Low-Sulphur Diesel. The Sinclair stations in town (owned by Haycock Petroleum) are selling B5, but it is a blend of 5% BioDiesel and 95% Ultra-Low Sulphur Diesel...

I know this may seem to be a rather trivial difference, but which would you choose given these two choices?

It seems my 350SD runs better on B20, but I only run on the diesel tank until my GreaseCar WVO tank is hot enough to switch over - so I'm running WVO at least 80-90% of my driving time.

Any thoughts?

Blevinsax,
What are your winter night temps like? Desert temps can drop pretty low.
I've been to Nevada in the winter and a couple of times it was pretty chilly.
Chilly enough (40ish) to give you some hard cold starts with B20. I would use B20 in the summer and switch to B5 as your starting fuel for the winter to heat up your WVO. You don't need both fuels gelling up on you.......

B20. If it's quality bio made with soy or canola, the fuel will tolerate temperatures below 0F. I've run B40 (commercial B100 heavily winterized) to -20F without plugging a filter.

Good to know! I am still a little concerned with the quality of Biodiesel in the Northeast, but may be by now that is changing with it being more regulated.

Blue Sun in Colorado claims a -20F CFPP for their B20. That can be further protected to -30F with regular diesel anti-gels.

Regulated does not always mean better...
