Slowmover's metric is right on. While there are certainly political and social reasons to use less petroleum, isn't our desire to spend less $$$ to get somewhere else the relevant point?

I haven't run the numbers on trucks because I wouldn't want one no matter what, but diesel SUVs, even with their higher mpg ratings, don't seem to have better cents-per-mile capability than their gas engined siblings. Diesel fuel being 20% more expensive than gasoline mostly negates their efficiency advantage. When you combine that with higher maintenance costs and higher purchase price I don't get the attraction.

I was very interested in a diesel jeep GC but just couldn't make the cents-per-mile work out better than the gas engine model. I'm glad I bought the V6 every time I see the gas station sign with regular at $3.30, diesel at $4.00.

Diesel is more expensive but packs more power and generally produces less CO2. Now re-read my post. There are differing ratings for Bang for Buck or cents per mile based on type and grade of fuel. For me my alternative to my E-250 Bluetec car, which cost less by the way than the gas models, is an E-350 which requires PREMIUM gas, costing about the same per gallon as Diesel. Its a no-brainer. Diesel engines generally last longer and require less maintenance in the long run.

The gasser version of DODGE diesel trucks generally has less power, and is expected to last (given controlled wear rates) about 60% of the life of the diesel (on a FORD or GM diesel engine life is at parity with the gasser).

Then there is difference between drivers in comparing similar rigs. Among professional drivers the gap is 30% in FE. With amateurs, even more.
