Years ago, we decided to move our entire fleet to diesel. Previously we had both diesel and gas pumps in our yard and it was a real hassle. We would have to order and keep track of three types of fuel (on-road diesel, off-road diesel, regular gasoline). Guys would forget what they were driving and would stupidly put gasoline in diesel trucks. Gasoline tanks and pumps had to be tested and certified regularly, ect. Transporting gasoline was a hassle beyond 20 gallons. Eventually, we just got fed up with it.

Now, everything we buy is diesel and it's great. Whether it's a generator, a welder, a pickup, a dumptruck, class 8 tractor, whatever.

The only thing we don't like about it, is the selection of diesel vehicles here in the U.S. is kind of lacking. We're basically stuck buying heavy duty pickups and vans in applications where lighter duty vehicles would do. Somebody needs to bring out half-ton and smaller diesels that aren't expensive luxury vehicles.

A diesel option for the Expedition would be great. A diesel Transit Connect would also be a wonderful little run-about (and they sell them everywhere else in the world but here ).
