Diesel Cars Make a Comeback in the U.S.

Scientific American -- Gone are the days of riding in the family station wagon, inhaling smelly, sooty fumes from a noisy diesel engine.

Diesel engines have always been more efficient than their gasoline counterparts, but over the last decade, the autos and the fuel they run on have had to come a long way to shed their dirty image. Today, diesel cars offer Americans another fuel-efficient vehicle option that could also ease the pain at the pump.

"The great thing about diesel is that it's coming in at the right time," said Allen Schaeffer, executive director of the Diesel Technology Forum. "It's proven itself as a technology, and it has the credentials to compete with policymakers and customers that want to drive a car that's good for the environment and low in carbon dioxide emissions."

When you think that you get about 35 - 38 mpg w/ the same car using a gasoline engine, that's a pretty big difference that still adds up fast.

I started with cars that got 40 to 50 MPG: 1979 I bought a brand new VW Rabbit D in 1978, I bought a second ne used. 1981 Rabbit D pick from E-bay 1985 Golf for $800, used 1986 Suburban 6.2 Diesel 4X4 I bought two of these in the 1990's.These got 18 to 20 MPG, cost around $2000 each used I replaced them with a 1997 6.5 turbo K2500 pickup 15 MPG I replaced the Golf with a 2003 Golf TDi I picked up a 2011 BMW 335d which came with a $900 tax credit and 4 year 50,000 miles of service included! They were there all the time if you wanted one and looked for them!

The new diesel cars are great at squeezing more mile out of a gallon. Its like buying concentrated fuel. Pay a little more for it, but you get alot more miles out of it. Figure out the cost per mile. Maintenance cost is comparable to gas from my experience. I see it as a win-win.
