I own a 2008 3500hd sierra duramax, I was a little slow in buying new, but the prices for used was almost new price. The price of diesel fuel has gone way to high, but i will add this that my truck get between 15.9 to 17.1 miles per gallon around town if i keep my foot out of it, but with the power it has its hard to do. The freeway mileage i get between 19.8 to 21.7 if i keep it under 70 miles per hour,My gas 2500hd only got 10 miles per gallon on a good day, so it was a good trade for me. It has been a pleasure driveing this truck, I didn't need the 3500hd but it was the same price as a 2500 hd so why not. would do it all over again in a heart beat. You ford guys can keep them, make mine a duramax.

That's much better mileage than what you'd see with a PowerJoke Ford. Also, the Chevy simply blows it away in all acceleration contests and in reliability of the powertrain and transmission. Good purchase. You're getting the same mileage as I am with a 5.7L Tundra.

Ford needs to do some homework. Maybe for 2010 they'll actually bring out their own V8 diesel instead of purchasing them from ITEC/Navistar. They are locked in a nasty court battle and those SRA (smart remote actuators) are prone to overheating and making the VTG mechanism go into a "limp home" mode = poor mileage.

I can say plenty, Ford is losing market share at an alarming rate.

As Gary Hamel said: "you must build a legacy...not live off of one"

The days of selling 900K F150's, 400K Exploders, and 200K Expeditions are laughably over.

That's OK, Mulally will get $40 million next yer.

Also, please remember that Ford is well behind GM and Toyota in global vehicle sales. Take a drive through Dearborn while you still can breathe in some of that Ford fresh air. Good day mate.

Again Ford outsells Chevy, GMC and Toytoa combined. To add Ford, sold just shy of 800K in trucks last year. And the Explorer is dead, but not buried they still sold over 10k last month. Maybe you have noticed that crossovers have replaced it?? Edge maybe?

Again, living off a legacy. What are they doing this year? F-series sales down 24% for March and quickly fading. The mildly freshened (no powertrain improvements, no MPG increase) 2009 model is likely to hit the streets cold.

Ford can sell all the trucks it wants, it posts losses every year. The more they sell = the more they lose. Brilliant economics in Dearborn. But as I said, Mulally will get a massive bonus for destroying market share.

ford outsold everyone until 2006 when gm surpassed them. as for the mileage, i also have an 08 3500 that pulled 22.3 mpg when i drove it home from the dealer brand new. it has since jumped to 23.1 with only 1200 miles on it. i'd like to see any other gas or diesel light duty truck do that completely stock. only one that would have a chance is the cummins. as far as a gas tundra doing 21 mpg, were you driving 50 in a 70 dude? with a 40 mph tailwind? keep dreamin. gm rules!

Tundra pulls 20mpg EPA estimates (new calculation for 2008) so 21mpg is certainly possible and I have achieved it on many occasions. It's called a 6-speed tranny with a nice 6th gear ratio to keep the RPMS low and a VVT motor that can adjust base cam timing (try that in your DuraMax).

As for your wet dream of a 3500 with a Duramax getting 23.1mpg.....well dream on brother. All of your diesel forum buddies are getting well below that. Once diesel went up in price all the diesel owners started bragging about ridonk mileage as a way to "ease their pain" of paying a premium for a truck that gets no better fuel economy, is often unloaded or not towing, and now the diesel fuel costs 20% higher than gas.

Sounds like owning a diesel just will never pay for itself with the current economics.

Dmax is awesome engine but way too big for my needs.

GM needs a small diesel maybe a 6 cyl to put in the half tons and 4 cyl in their mini trucks.

yeah,
but the big advantage of having a diesel is you can make your own fuel and tell the Big Oil greedy fks to go to h311!

Buy a Dodge that's made in Mexico? A Chevy that's made in Oshawa, Canada?

My Tundra was built in your ISP location you tallywhacker. Man, you Texans are pretty dumb, I must have gotten lucky since I've had no issues with my truck. Mexicans are smarter than ya'll.

who ever you are "built ford tough" if all you can say as a come back is "Ford outsells Chevy and GMC and Toyota all together." HA HA HA you shouldn't say hurtfull things, why dont you come up with something original and even if they did out sell that doesnt mean they are a more reliable vehicle just that they are cheaper and there is saying "you get what you pay for." plus then you seriously need to do a little more homework before opening your mouth. ford does not out sell any of these companies. And ford sales, as was stated is drastically diminishing. ford tryed to bring out a number cars and trucks that were supposed to give them an edge and all of them have been flops for ford.

This is cool, all you brand loyal folks poking fun at each other, who cares which one out sells the other, drive what you want, good lord it's America man.

I personally own a 2004 D-Max and love the hell out of it, my mileage isn't that high but I can live with the 19 miles per gallon and the HyperTech chip. I can't believe the power this thing puts out.

That old wives tale about Ford out selling GM is cute, the real tell tale sign is just look at the resale price of used when it comes to GM versus Ford, absolutely no comparison. If you take the same comparable truck be it loaded or not there's thousands of dollars in worth that put Gm into a whole different class of truck.

Listen penis. Ford outsells GM year after year and there is a reason, because Ford is better. Chevy is junk. My friend bought a Chevy diesel dump with the Duramax and Allison trans. The thing is the biggest piece of junk, everything has had to be replaced all major work, everything is blown except the engine. Chevy is in a differnt class, the junk yard. Consumer reports just made the list of the worst used cars and trucks and they were all Chevys. GMC's and GM's no Fords on the list just the Lincoln Aviator. So you have no idea what you are talking about dummy.
