Will the savings be worth it? With diesel being roughly a dollar higher than gas if gas is $2 and diesel is $3 than it would have to be roughly 33% more efficient than gas to make it worth it. Are They typically 33% more efficient? I am not sure that BMW's engines are except for maybe the 23d. I would really like to consider this in the next couple of years for the wife's upcoming small-midsize suv. Especially if I could fill with biodiesel (like to support ag industry).
