you never said anything was differtent between your 2 trucks. just that your 04 got worse mileage. considering all new trucks with DPF get worse millage than previous years models i think he was making a very accurate assumption.
You guys crack me up sometimes. You get on your high horse and preach about someting you have no knowledge about.
If you had a Duramax, you would know that the new models now have more horsepower and torque and sixth gear.
Also, how can you say all new trucks with DPF get worse mileage than previous year models. Mine doesn't. If you want to preach to us, back it up with some facts. Also, I looked at turtle n peeps posts and he is driving a 93 or so tow vehicle. Why are you and he replying to my post about a Duramax when you have no personal experience with one?

I have experience with them and I can say one thing mine will not get as good mileage not towing. But I have gotten better mileage towing. Go figure.

A diesel achieves this with an intricate system of on-board computers, sensors, levers, gears, pumps, and other technologically magical sophistication that quickly corrects the loose wires in the driver's brain that cause those pesky thoughts of caring about "the environment."
I "do my part" by going easy on the go-pedal until I can filter my exhaust through a Prius filter. That is, I wait until a Prius is tailgating me, then I nail the go-pedal. The black sooty cloud of exhaust emitted from my diesel then quickly enters the Prius' engine and cabin filters for purification. I feel good knowing I'm doing my part to save the planet.

I for one have both a Prius and a GMC 2500HD D/A. But my diesel has the DPF so I have no need to filter my emissions through my Prius.
Very funny though.

That is a great attitude to say something is wrong with the 04. Was it the first thing that popped into your mind.
Pretty much. Where do you think those quarts of fuel comes from when your LMM goes into "burn" mode? I'll give you a hint. Your fuel tank!!! The reports I have seen says around 3/4 of a gallon to a gallon + depending on how plugged the DPF is.
Quote: Before you make statements you ought to take into consideration things like more torque/horsepower while pulling a large load and oh yeah, how about that extra gear I have now.
This is exactly what I'm taking into consideration. Where do you think the extra power comes from? Again I'll give you a hint. It's fuel flow. Look at the fuel curve of the LMM VRS the LLY. Oh geee, the LMM flows more fuel!!! Diesels get more power by drinking more fuel. When you put a box or chip on a diesel they jack the fuel rates up. This is where the black smoke comes from. Oh wait, your LMM just uses fuel to clean the air but no black smoke!!!
Quote: I can travel highway speeds now easily saving a few hundred RPM's.
Yep, you got that one correct. BUT, that darn DPF just drank up that savings and gulped a few more too boot.!!!

I just did. Please read above. Those are the facts.
LMAO, I have a 93 and an 06 LBZ and a 5.7 and two diesel tractors. I tow with the 93 when I want to save some fuel. Even though the LBZ has that 6 speed you like so much. My 93 will still use less fuel because it can only flow about 225hp worth of fuel. The same for the old rattle trap 12V Cummins. They will smoke any 6.7 out there if you did a fuel economy test. Those old 12V's get super milesge.
I crew chief for 3 race teams and drive for one. Won a championship last year and was first place looser the year before. Owned several track records and build all my own engines. Owned, built and driven several 10 second street cars and I'm building an 8 second street car right now.
And just what are your qualifications?

I taught auto shop for 23+ years. Turned all kinds of kids into motorheads just like you! I know where you are coming from, but I learned a long time ago not to make broad generalizations. There are no winners.

I disagree with their decision but that's what we get for having our regulatory agency ran by radical leftists. Even europe disagrees with our thinking because their environmental regulations are focused more upon reducing C02 emissions.
Agree with your post but one comment to your statement above:
Euro lefties typically make ours look centrist. After all, Socialism is just a function of the radical left.
By not focusing on CO2 emissions and taxing the heck out of fuel, our government in many ways gave our economy a distinct advantage...though we pay a high indirect price for our foreign energy dependency.

These little trucks don't use anywhere near a gallon of fuel per regen. My 16L engines only use .8 gallons per regen and the dpf is 15 times as big. The real reason for the decrease in fuel economy is due to EGR. EGR was introduced in 2002 and the NOx level decreased again in 2007, MORE EGR! The dpf regens periodically whereas EGR is used constantly. If you haven't noticed, only one of your engines has an EGR cooler and it's not the one you tow with for fuel economy.
When 2010 rolls around, I will guarantee an increase in fuel economy from GM and Ford since they will use SCR. They can decrease the amount of EGR and clean up the NOx on the back end. I also suspect the dpf will utilize more passive regens since the high NO2 environment is perfect for that. The cost of urea will be negligible at less than a half cent per mile.
Also, since none of your race engines use HPCR fuel systems, you wouldn't know about injection timing and mutliple injection events per stroke. This is where the increase in power is coming from. The increased power isn't burning more fuel, but the decreased thermal efficiency due to EGR is.
Wont these new urea systems only promote more beer drinking and driving? Since in the middle of no where when the tank runs dry all you will need to do is stop along side the road and pee in the tank. Good to go for another 100 miles OF course you will need something to make you pee
Years ago I heard something and believe it is still true to this day. Those that can do, those that can't teach! Have a good day Y'all
Powerdude said: "There is no such thing as global warming, because 60% of global weather is governed by the sun's output."
Just as a guess, I'd say it's a lot closer to 99.99996% of global weather that's governed by the suns output. If it weren't for the heat from the sun, earth would have NO weather except for that caused by volcanoes occasionally bursting through the surface ice sheet of snowball earth.
