I always worried about the two mixing. I thought they had to do something funny to the bio to make it actually stayed mixed w/ the diesel - - you know kinda like Oil and Water.

 

You can research it to be sure, but I beleive the two mix readily. There are a lot of "tree hugger"sites that will give you plenty of info for free.

 

I don't know much about diesel, but there is a gasoline refinery here in Lima, Ohio and I can tell you first hand that there will be tankers from all the different stations that just back up and get the fuel from the same place, I think people are stupid when they say things like "wal-mart gas is watered down." Again I don't know if the same goes for diesel.

 

The same goes for all fuel. The difference is the additive package that each company adds AFTER they get the fuel from the refinery or pipe line. So you are correct in one sense but incorrect in another.
