I love diesels.I'm driving my second one now and will *never* again drive anything else.Thanks to its outstanding fuel economy I firmly believe that diesel can be a big part of the short term solution,maybe even medium term.But if the reports I've read about *our* supply of natural gas are true I think that *it* is the answer...long term.
As you may,or may not,know about half of the passenger cars on the road in Europe today are diesels.In fact I've heard it suggested that Europe and the US have it exactly wrong,given their particular transportation needs...Europe should be driving gasoline cars and we should be driving diesels.Go figure!
I keep 12 months of usage in reserve.
