Patrick,

Congratulations on having a wife with her brain in gear. The advantages that diesels used to have over gas engines are going away fast. When I ran diesels alot in the seventies, eighties and even into the nineties, diesel fuel was cheaper than regular gas. In addition, compared to carbureted gas engines, diesels lasted alot longer and got much better fuel mileage.

Now that we have injected gas engines, they not only last longer but also get better fuel mileage. The diesel advantages have narrowed if not totally disappeared when you factor in the difference in fuel prices.

A very perceptive woman you have there.

Good luck,
