Default Duramax fuel mileage?

Hey all,

I am looking at maybe getting a 2500 diesel truck in the near future. What kind of MPG do you guys get on your stock (or close to it) duramax`s? Also what year do you have?

Thanks

2006 Crew Cab Shortbox.

City: 18
Highway: 21-22
City Towing: 16
Highway Towing: 18

The only modifications are we went with 285 tires instead of the stock 245's. These trucks don't even get broke in til they hit 100,000 miles. My Dad has a 2001 Duramax at his shop that is nearing 500,000 and they still run it every day

They make the same mileage but the Duramax has ton's more pulling power that one needs but it's more $$$$$$$$ and it's more durable.

I just sold a '07 with 25k miles. It consistently got 15-16 around town and around 20 on highway. I don't have any towing numbers. It was a great truck, completely stock, but when diesel fuel got so expensive, it was a pain to fill up.

I ran my old diesel up to 254K and sold it as I just didn't want to put the money into the body that it needed. I looked very hard at Duramax trucks on the used market. I just couldn't make the numbers work, the premium price of the Duramax just wasn't worth the extra cost. Unless you tow heavy or drive 40-50K a year the diesel will never pay off.

Figure your average mileage per year, divide that by the mpg of the vehicle you are considering and compare. The diesel is very hard to justify financially for most users. If you WANT it and can afford it then that is a different thing entirely.

The cost of fuel is not really significant if there is only a few mpg's difference over a year. That's why all those performance and mpg mods aren't such a good deal once you figure out how long it takes to pay them off. Nobody wants to hear this but it makes far more sense to buy a gas truck instead of a diesel and spend the extra money on a used Civic, etc. Once the mpg difference is between 18 and 30+mpg the payoff is fairly quick.

Unless you gotta tow something BIG...like 12000lbs of boat/trailer.

Hell yeah, that is what I am talking about. Using the truck to it's max. Not over maxing it, just use it for what it is intended. PULLING.
No matter what truck you get, it all goes back to the heritage. Pulling on road, and hauling on/off road. Tractors were unfeasable to travel long distances, so along came the truck. To haul and tow long or short distances.
