Mike, That is, by and large correct. There is a slight horsepower reduction when running biodiesel neat. Some would jump on this factoid like a cat on a rat, screaming "I told you so," and other mindless declarations that berate bio-d. When they do this, they immediately neglect such minor details as enormously cleaner air, greatly reduced carcinogenics in both emissions and manufacture (read "reduced medical costs and human suffering"), fuel renewability, enormously increased biodegradability, conservation of petroleum feedstock for future generations, strengthening the economic outlook of family farms and a herd of other side benefits. My perspective is that such individuals have either not thought the equation out fully or are highly selfish. If they keep their britches on for a decade while this industry gets off the ground, they will probably see biodiesel energy content increase, if through nothing else hydrogenatiion. This process breaks down double bonds and adds hydrogen to the mix, increasing energy value. A bit of an industrial process, that. Refer to ASTM standardization for data on cloudpoint, lubricity and coking. No one has really done much on the latter.
