I have a station near me that is selling a fuel advertised as "Premium Soy Diesel". I inquired about the fuel and received the following information:


The product is Soy Methyl Ester blended with a quality diesel fuel. The crude soybean oil has gone through the transestrification process and is considered pure bio-diesel
or B-100 Neat. Also, it is made from 100% soybean oil. It is not a blend of any other vegetable oils or yellow fats. The blend being sold is a B-2 blend or a 2% blend of Soy Biodiesel and 98% traditional diesel fuel. The cetane of the B-100 is in the 51 to 53 range.

The price is about 10 cents a gallon above everyone else. Is this fuel worth using or am I wasting my money? I, of course, like the idea of using soy, but 2% seems a little low. So... You fuel gurus... What do you think?

As I understand it, "methyl ester" is the product produced by the transesterification process using methanol. No methanol remains after the process, only the methyl ester and glycerol.

You'll want to check these two sites, then Cummins statement about Biofuels and their warranty.

That high of cetane isn't really going to help that much. What Biofuels do is lower all emissions, except NOx.

Running B-2 is pretty close to straight diesel, so you won't see much in the way of differences. Run it if you want to help the American farmer.

I've run B-10 and I see a very slight reduction in mileage and the exhaust smells a bit better. The station around here that sells it has some kind of govt grant, so its price is about the same as diesel.
