With the rapid inflation of diesel fuel prices, what do the calculations show for cost per mile versus the gasoline versions? Even after factoring the higher initial cost for a diesel, there used to be a clearcut cost per mile advantage for diesels due to higher mpg and lower cost per gallon. I haven't had cause to look at it recently, but your post got me thinking about it. If the price gap of diesel to gasoline continues to widen, I've got a feeling that any advantage diesels had is going to evaporate, if it hasn't already.

I wish I could calculate cost per mile or even est. but I would assume pretty low, given VW track record for reliability, and durability,they have been making diesel motors for years that seem to keep on chugging with little to no maintenance.... to compare their gas motor jetta to their diesel, the gas motor gets an est. mid 20mpg rating / where as the diesel gets a est. mid 50mpg rating... this is a huge difference... there is not many cars out there besides a few hybrids that can do that, and remember this isn't some little tiny car, it is a decent size commuter....
Just my two cents but i don't think we are going to see a jump in diesel price that could make it more costly to operate it than its gas counterpart...
now for you full size truck guys it just sucks cause the gain in milage does not outweigh the price of fuel or maintenance so I agree with you.... sorry!!
