Thanks. You really should get out more. It's a big country. There is no conspiracy to reduce MPG. There is no magic carburetor. To get high mileage with an internal combustion engine, you need a small, very aerodynamic car. If you think that there is so much market demand for these cars, then why not sell them yourself? Most of the high mileage diesels in Europe are turbocharged. I don't want to own a turbocharged engine. It is more efficient, but less reliable.
