Talk to your fuel supplier. You can only buy it with a blenders license and a fuel tax license. If you use it at the 2% level it replaces an oil based additive and is economically competitive. Right now, with the price of diesel, it's 8_10th of a cent per 1% blend. States seem to have maximums that you can run. Once again, your fuel supplier should know. If they don't call your state Soybean association, and they should know. Chads
