My "guess" and it's only a SWAG, is that most diesels get double + the mileage of most gas powered vehicles of similar design. For example, my 98 Landcruiser gets 9.5 regardless. A Diesel version of the same vehicle gets upward of 25-30!!
I just figured the companies jacked up the prices to make up the difference in use
As far as my driving habits? I probably drive less for work (I now deligate a lot of this BS), and when I have to take out of town business trips, unless I know I'm going to the boonies or the weather absolutely sucks!, I take the vette. It again get's double+ the fuel economy:thumbsup:
A little off topic, but where do train in Kenpo up there?
