Study claims diesel vehicles are cheaper to own

A new survey has been published looking at the cost of ownership for gasoline vehicles compared to diesel vehicles. The University of Michigan conducted the study for Robert Bosch, LLC.

The study determined that diesel vehicles save owners between $2,000 to $6,000 in total ownership costs during a 3- to 5-year period compared to similar gasoline vehicles. The data was compiled by the University of Michigan Transportation Research Institute.

"Overall, the results of our analyses show that diesel vehicles provide owners with a TCO (total cost of ownership) that is less than that of the gas versions of the same vehicles," according to the study. "The estimates of savings for three and five years of ownership vary from a low of $67 in three years to a high of $15,619 in five years.”

The study claims that Volkswagen Jetta owners saved $3,128 while Volkswagen Golf owners saved an estimated $5,013 compared to owners of similar gasoline-powered vehicles. The study also finds that all of the diesel vehicles had better miles per gallon figures then gasoline versions with diesel is offering between 8% and 44% higher fuel economy.

The study also shows that nine of the 10 diesel vehicles held their value better the comparable gasoline vehicles.
One has to keep in mind, however, that Bosch has quite a big financial stake in these results as it produces high-pressure fuel pumps for diesel manufactures like Volkswagen which have a tendency for failing in late model vehicles.

Come on, you are just teasing him. He's talking about spark plugs, ignition coils, and spark plug wires. Those are countered in a diesel by glow plugs, DPF, and urea solution. Any dually meant to pull horse trailers or boats is going to be less frugal than a petrol model. A Jetta 2.5 or 2.0 is going to be less frugal than the TDI model. Same for the Passat and apparently for the E250.

Glow plugs = ~120k+ miles, most people run it way past that. It's common for a diesel car to have original glow plugs its entire life.
DPF = ~120k+ miles, only newer diesel cars have catalytic converters so you can't even say it's an extra part all the time. At the same time, many gas cars have more than one cat converter.
urea solution =~10k miles and barely cost anything.

Maintenance intervals for diesels are just longer and there are less wear/tear on the drivetrain due to its efficiency.

I guess I just can't argue with someone who thinks a jetta 2.5 is going to be less frugal the TDI model. Logic just went out the window there.

Whoa, major reading comprehension fail. Less frugal means it consumes more gas.
