Gas mileage will be improved on the diesel but with the cost of diesel fuel escalating, I'm wondering what we'll see down the road. With more and more companies bringing diesels to the US, I would guess that diesel fuel will be at more of a premium in price and maybe even in short supply, therefore owning a diesel could be a problem. I can't decide whether to buy another x5 gas guzzler now or wait until spring for the diesel. Are there significant performance factors that make the diesel really worth waiting for in spite of the high fuel costs? Any thoughts?? Thanks.

Let us hypothetically take the average MPG for the diesel as 35 and that for Petrol as 20.
Let us hypothetically say that you do 12000 miles a year.
1. For a diesel powered car, that will bring you to 343 gallons, resulting to a cost of $1265 a year on fuel (343 x $3.69)
2. For the petrol powered car, you will require 600 gallons, resulting to a cost of $2154 a year on fuel. (600 x $3.59)
The savings from using diesel = $(2154- 1265)= $889/yr.
Over 5 years = $4445.
Something else that you need to know, this(US) is one of the few countries in the world where diesel cost more than petrol.
