I have to admit that I occasionally find it a mite irksome that shortly after I dump a bunch of cash on the diesel sedan I've yearned for for years, whammo, the price of oil crashes and, because its winter, the diesel/gas price advantage purty much disappears, leaving me paying more per mile than the gassers are. But ya know what? I remind myself that its mostly people who know squat about diesels who base their decision solely on the cost per mile calculation. I love everything about diesels: I love the huge power packed in a compact little engine, I love the sound, I love the engine's incredible reliability, I love the fact that I'm now producing 30-50% less greenhouse gas emissions, and contributing 30-50% less to our national strategic insecurity.
And, when I think about it just a little bit longer, I love the fact that this too shall pass, and before ya know it oil will be back up to $100/barrel and my cost per mile advantage will be back.
