how much does biodiesel go for a gallon when you buy it from one of these supply stations? I found one off of biodiesel.org that is 75 miles from me but might be worth using my truck rather than my girl's car if I'm headed down that way.....
The price can vary greatly depending on the source of oil. The amount of BD in the fuel will also result in price variations. Blend prices for B2, B5, B 20, etc., will vary depending on the petrodiesel price.
I priced some high quality 100% Washington-grown canola oil BD99 yesterday, and it's at $3.15/gal. (we paid as high as $3.39 last August for #2 petrodiesel). Canola oil makes the best quality BD and can be difficult to find in my area, so I'm willing to pay that price at this time and blend my own. Petro diesel is currently around $2.20 in our area, so I can splash blend my own B20 for around $2.39.
You might give a call to the station your are looking at buying from to ask what their price is. I'm sure you'll find a lot of different prices.
i usually get B100 for $3.25 a gal develered to my house. i have found it at the pump for as low as $2.99 when i was traveling through Santa Cruz Ca. B20 at the pump is $2.85 when diesel is between 2.69-2.99 around here.
