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.

Total Cost of Ownership?

I honestly am considering making the jump to diesel flavor but am curious, how much would it cost to replace applicable parts like a timing belt, water pump, serpentine belts, etc.? I think these parts should also be factored into this TCO study.

I've also heard that traditionally, German automaker maintenance has been relatively more expensive than Japanese vehicle maintenance which is why I'm happy to pay only $350 for a timing belt/water pump replacement for my Civic and Accord.

Timing belt with water pump can cost $1000. Some places less, some more. Sometimes the serpentine belt tensioner (it rattles sometimes) needs to be replace along with the belt itself. You can do the serpentine belt yourself though and save some cash. I think the belt is $30 but the tensioner is like $80 or something like that.

And in the case of my F350 & 550, it used to be over $170 for a full synthetic oil change and filter.

I switched both over to oil bypass-filters systems. Now each one holds over 6.5 gallons of oil. My 550 is now over 102K miles with the same oil, minus what oil is lost during the filter changes every 25K.

But yeah, people don't tend to realize that maintenance on a diesel tends to be more often and the parts can be quite a bit pricier. The other big issue is that a rated diesel mechanic can be double the hourly rate of your normal gas engine one.

It sounds like you're coming from the world of larger trucks, not economical diesel cars. As far as maintenance goes, the schedule on my 2013 Jetta TDI is oil change once every 10k miles. They do change the fuel filter with the oil change. But VW also includes all scheduled maintenance on the TDI for the first 36k miles for free. At any rate, when you consider that gasoline engines will want roughly 3 times as many oil changes (now who needs maintenance more often?), you can still pay a little more for the TDI oil changes and come out well ahead.

Labor costs at the VW dealer are the same regardless of which engine you have.

That is only if you buy into the oil company sales recommendation of changing oil every 3000 miles. Using synthetic I have been going 10k miles on every oil change in my gasoline vehicles with no problems for almost 20 years. Most vehicle manufacturers even state oil change intervals for gasoline vehicles at 5000 to 7000 miles now days.

Last study I heard, the Japanese still beat everyone in reliability.
