biodiesel becoming the norm?
It's been available at the local Exxon's and a Marathon on a secondary pumps for a few years. Yesterday I stopped at Walmart and their main pumps had new B20 stickers on it making it the only diesel they sell.
Glad I upgraded my fuel lines. I wonder if others will even notice or know they need to. The Walmart diesel pumps here are always busy and usually have the lowest prices.

Lucky you! I wish we could get it more easily out here in the west. Love's truck stops used to have B20 at all their diesel pumps, but they stopped at some point in the last year. I can't even get it anywhere within 300 miles anymore.

B20 is 20% biodiesel, 80% conventional diesel.

It's slightly more generic than that:
B5 is up to 5% bio blend
B20 is 6-20% bio blend.
What makes up the biodiesel, I don't know. I suspect it's not the same everywhere, but more state by state. I believe Tennessee is giving tax breaks on B20 and above, not that we see it at the pump. For the most part standard USLD and B-whatever are the same price, $3.72 today.
I just like that it's getting easier to find and the lubricity value for our older engines.

Diesel went down to 4.90 a US gallon here in Canada. Was 5.05 a few weeks ago.
It's costing nearly 80$ per tank to fuel up my van.
No biodiesel around here yet.
Any advantages or bad things about it?

Advantages -- lubricity. Better than any additive.
Disadvantages -- much higher cloud point (important for those of you in the great white north), meaning it forms wax crystals at a much higher temperature than No. 2 or No. 1 petro diesel. This isn't much of an issue until you're running a higher than 20% blend.
And it'll dissolve the 30+ years of crud in your fuel system and plug filters for a while. But you'll have a cleaner system afterward.
Also, it has fewer BTU per gallon, so you might see slightly lower fuel economy. I consider it a good trade off though because your engine will last longer.

Sure. If you're up for a little light reading, check out Chevron's paper on the subject.
