Diesel is about 11% more energy dense by volume than gasoline. So if you're buying diesel for less than 11% more than gas, you're getting a good deal.
When I was looking at cars the diesels had a premium of about $5,000 over the equivalent gas car. That's over four years of gas if you drive 15,000mi/yr at 50MPG and $4/gal or 3.75 years at 45MPG. That's something else to consider.

- Retric 13y agoI get 40MPG highway with a 200HP gas powered car that uses premium gas which costs about the same as diesal. With 4$ gas that extra 10MPG would take 250,000 miles to break even. Unfortunately Diesal also costs more to repair so your looking at well over 300,000 miles before break even vs a small but sporty car.
