ok guys i have finally found a gas station that carries b5 and b20 at the pumps!!
it was a crystal flash in grand rapids, MI and i was going to be near it yesterday so i filled my 95 up with b20 to see how it goes.it was 2.94 which is what their diesel was advertised at so it wasn't any more expensive.

here is the site that helped me find it...

sweet we have b10 at a few places in san diego but its like .30 more. finally saw diesel under $3 a gallon finally......

 

I must be doing something wrong. I get "no matches found" in the state of Arkansas. Good thing I already know where a couple of bio stations are.
