diesel fuel contains approximately 11% more btu than gasoline,and motor oil[wmo] contains approximately 20% more than gas. that translates to fuel mileage. i run a wmo blend and i can honestly say that the wmo blend i use gives better mileage, gives noticeably more power, and my wife claims it is quieter. the big advantage is my price/gal =<.10/gal [collection and processing cost]. years ago, i bought my 1st diesel because the fuel was cheaper than gas, that is no longer an advantage for owning a diesel, today for me, THE advantage for owning a diesel is you don't have to run diesel.

thanks, hunt

Well, I've only been driving since 2002 ;) and I recall it generally being higher in my area.

He's referring to the engines themselves, i.e. the VE is 30% higher in diesel engines than gasoline. While I can comment if that is true or not...
