I'm headed up to the Redwoods for the weekend and I figured I'd fill up in Santa Rosa since they have Biodiesel. I have an extra filter in case it clogs up, but what should I go for ratio-wise?

B2
B5
B10

Ya, I'm aware of that...My concern is Dodge says B5 max to not void warranty (Out of warranty currently), but on Fleet vehicles I recall they listed B10.

B2 gives better lubricity than any other fuel additives available, but I'd like to go as high as possible to try it out.

I doubt you will notice a difference no matter which ratio you choose. If you want more of a detergent action I would imagine you should go with a higher concentration.

I know my rig doesn't like more than 50% bio.

Propel in Sacramento area has b20, I run this in my 2005 every other month, with no issues.

Went with B20, probably B15 since I wasn't on empty when I filled her up.

She didn't like it much in the higher elevation or long upgrades, but at sea level, she gets along quite well and is much quieter.

What did she say? BioD does have a little less punch/power, but hopefully you bought it at a discount.

It was a dime more than regular #2, which I was fine with, it was still cheaper than the immediate bay area.

She seemed to have more rattle on long grades/higher elevation than when I run straight #2 at even higher altitudes.
