My believe is Once You Go Diesel You Won't Go Back . I have a 2008, 2500HD, Mega Cab with a 6.7L Cummins and 68RFE Auto, to pull my 5er and just my general driving around for me. I plan on keeping this truck for a minimum of 300K miles.
This year we went and bought my wife a 2011, VW Jetta TDI with the DSG transmission, this too will be kept for a minimum of 150K miles. The fuel mileage on the Jetta is 36 mpg combined city/highway through 4K miles. Per the EPA testing the gas version of the Jetta is 23 city and 29 highway. I have never been able with a gas vehicle to achieve the EPA estimates for driving, they are usually 2 to 3 MPG under their estimate.
My wife drives the car mainly in the city, which is between 30 and 35 MPH speed limit with stop and go traffic. So to me we are saving more money with the diesel engine and I still believe that diesel is the best fuel for vehicles for long term efficiently.
