2011 GM Duramax upgrades......

[JupiterSunsation]

GM spent some money on the chassis upgrades and "reworked" powertrain.......meaning the Duramax will be rated to pull 20,000 lbs in 2011.

I suspect that will be in a gooseneck setup and in a 2WD dually with 8 gallons of gas, a 120 lb driver and no passengers, empty truck right down to the glove box and no CD in the radio!

[fund razor]

No. The 20,000 is with the crew cab, long box 3500 dually and a 36 gallon tank. :D
Base tow rating for the new frame is 16,000

Don't hate. Appreciate. GM just came out with the fastest, most powerful production one ton.

Brakes went from 12.8" to 14" to accomodate larger wheel options.

New intake setup to eliminate the old snow collection in blizzard conditions complaint.

All new Allison tranny.

New optional allison driven exhaust brake, power take off and driver shift control.

Bad news: urea exhaust fill every 5,000 miles. (Welcome to enviro-weenie decade)
Also an't use chips and controllers without having them tattle to GM at warranty time.

I love my classic, but here is some info on the new trucks.

Also note "BIGGER WHEELS AND TIRES" unfortunately they look like they got taken directly from a Ford F350.

Fund- I am a GM fan, 9 new GM trucks in 20 years, still own 4 including a 150K mile Duramax. Just suspect their "test numbers" may be done Reggie Fountain style.......:D

"Look like, suspect...."

I'm not defending GM, just the facts. Your thread was a very sarcastic approach to your "suspicion." I thought I would put up some alternative viewpoints. I'll wait to see whether GM is "reggie" all of a sudden.

The nice thing about all the ford owners, doubters, malcontents and comedians who are "suspicious" is that it is driving up the value of our classics. Please continue. I would love to sell my LLY/LBZ one ton for more than I paid, if I ever let it go.

Maybe post this thread on every forum that you visit. :cheers2:

My 03 "classic" is a great truck but I don't suspect it is climbing in value..... To me the truck is a tool (long since paid for) and just like a shovel or any other tool I own I wouldn't buy another one just to have a new one. The old one has to be broken or unusable. That and I don't want to spend 50K on a new one! :D

[fund razor]

Right. Not so much the first generation LB7.
More like the third generation LLY and LBZ. (2006-2007) After most of the fixes and before the new emissions crap. Also, before the tattle tale ECM.

[fund razor]

My biggest issue with the new trucks is having to pay to have someone to pee in the exhaust every 5,000 miles. :D

Not sure about the 5K mile part.....I had two diesel Mercedes SUV's recently that also needed that refill and after 50K miles on one I never did it once. I suspect there is an interval but it can't be 5K miles...even oil changes are longer than that!

[fund razor]

I can only find references to 5,000 miles, whether it's the car and driver review, the truck forums, etc. The fluid will be used, so the tank will gradually empty and sensors in the tank will cause a limp mode condition if you ignore them.

[fixxxer22]

The new 2011 ford... If the pee pee tank goes empty the truck will warn you a few times then it will only idle. To force you to refill the tank. Our interval is supposed to also be in that 5k range. we just got our first 55 gallon drum of it.

Is this a simple enough process that the customer can do it? Easy as an oil change or windshield washer refill? Stopping at a dealer to have it done would be a huge pain in the azz if you have to do it every 5K miles!

[fund razor]

Maybe 3-5 bucks a gallon for the juice. (32.5 percent industrial urea and 67.5 percent deionized water) The tank holds 5.5, so saying you had a half gallon left when you refilled, that would be about 20 bucks to fill it every 5000 miles (less when towing according to GM, as the injection levels depend on exhaust levels to keep the mix of ammonia (the by-product of exhaust heat on the urea) and emissions correct.

[fund razor]

Sounds like a quote from the chinese man that you love, but I digress. :biggrinjester:

[fund razor]

Might as well show the engine too, huh?

[fund razor]

I guess I would rather have a DEF tank and a cleaner emissions truck than have the Euroweenies and Enviroweenies take the truck away altogether.

[MarylandMark]

At least mere mortals have access to it vs having to take it to the dealer.

[fund razor]

Hope it has a heater cause the DEF freezes at -7 degrees C, 19 degrees F, according to the internet.

[fixxxer22]

yes, the def will freeze at that temp so the tank is heated on the ford. Also it is corrosive so when you cycle the key to the off postition the pump reverses adn draws the pee pee out of the lines so they do not corrode and leak. there are warnings all over the barrel saying it will eat paint also. so dont spill! I go to training on the ford march 10th and will have alot of downtime in a hotel room between classes. so i will let you guys know all that i learn.

Comment on that picture above about the engine: When i went to new model training on the 6.4 the instructor said " you could stand on the radiator support and take a piss and no matter which way you aim your stream will never hit clear ground. It will hit something before it hits the ground.... So, you are welcome from Ford motor company" and we all laughed. The 6.4 is 10 pounds of crap in a 1 pound bag.

I have been told 7500 mile intervals to coincide with REGULAR oil change intervals. Normal, driving and idling conditions

I don't know of anybody who uses one of these for "normal" driving and I don't know anybody who goes 7,500 miles between oil changes.

so are you saying that 7500 mile interval is to soon or too long??????

[FULL FORCE]

I still don't like the idea of torsion bars on a HD truck, I agree the ride is nice but man when those fail.....ugly... had it happen in a small truck once... I would hate to be pulling my boat and have it happen.

20,000 rating on SRW??? not sure I would pull that much on SRW...

Kind of like some of the half ton trucks claiming towing ability to 10K, not pulling my boat or with my family in the truck!

[fixxxer22]

so are you saying that 7500 mile interval is to soon or too long??????

If i am correct in assuming that you have a 7.3 or 6.0 that is waaayyyy too long. 3k motorcraft oil and filter. It keeps the injectors happy. That high pressure oil system beats the crap out of oil. Oil is way cheaper than injectors.

[fund razor]

I didn't say it was too soon or too long. The Ford Tech answered that.
I said that I don't know anybody who goes that long. But if you do, I guess I know this one guy who goes that long. :)

Don't pull your boat with a small truck. :D

No, seriously... I have been reading your thoughts on the torsion bars so I went over to The Diesel Place where 106,000 members with duramax's are. I searched "torsion bar" and in hundreds of threads, there was nothing about a torsion bar on a HD truck going. Lots of thoughts about how far to crank them when you get bigger rims though. Not that it isn't an issue, but it doesn't seem to make the hit parade of GM gripes. (Like the "pump rub," the tranny cooler lines, etc.)

3000k is a little premature on oil change intervals for the 7.3 or 6.0 liter diesels, my master certified diesel tech and myself don't change the oil that often. Ford recommends 7500 mile service intervals under normal operating
conditions and 5000 miles intervals for sever duty applications. But what the hay does Ford know????

I don't know what is best. But the guys that I know are in the 4k-5k range. I guess they tow alot. Maybe your master mechanic doesn't. That would work out. Chris drives an Excursion with a 7.3 Powerstroke like some people drive a Kia. I'll bet he changes sooner than 7500. But I have no dog in the fight, and everybody does their own thing. I think that being a boater and building new power before has made me a conservative oil changer. When I change my oil in my Malibu at 3k, the oil life light (from GM) thinks that it has 2000 miles left, but that's ok. I'll err on the side of caution. Plus, I keep my vehicles a long time and this plan (early rather than late) has worked great for me. :cheers2:

[JupiterSunsation]

I go 5-7K on my 1500's with 4.3 motors and 6-8K on my duramax (holds 10 qts.).

[MarylandMark]

I go around 5K using the mid-grade oil. They call it "blue" at the place I go to, think it is Valvoline.

100 miles a year towing a 9K boat, if that on both numbers; other than that just a daily driver.

[fund razor]

I was thinking about this the other day. I change the oil (9 qts) in my 560sl in the spring and fall. I put 1,000 miles on that car a year. That's only 500 miles per oil change. :o

[Bill]

I change the oil in my Dmax every fall with Amsoil. BUT, that once a years is only about 3k miles...

I have my master status as well:cheers2: I change mine every 2500 to 3k mine is a daily driver. just had a 7.3 in yesterday that wont start cold due to stuck injectors. It is a 550 concrete truck and does not get the chance to get proper maintinence. I also have a truck that comes in every 3k for an oil change that has 400k on it and runs better than most 7.3 trucks with 100k on them. Keeping the detergent level high in the oil is the best defense for keeping the spool valves clean in the injectors. Which during prior approval the first question they ask when dealing with stuck injectors is "has the maintinence records been recorded". You can go 7500. if it were mine i would never go past 5000. Thats just my opinion. And you can go out to my 6.0 with 82k on it not plug it in and start it at 10degrees. no miss no smoke i could just put it in gear and drive away. My injectors are cleeeeeaaaaannnnn. Not trying to get in a pissing match here. Ford will honor all warranty at the 7500 mile interval. Rough service 5k. I just plan on keeping my truck for a long time and oil is cheaper than injectors and metal. :driving:

[Quinlan]

I change my D max at 5k max. The life still is 50% or so but i wont wait.
But the last time the oil life went to 0 and I only had 3K on it go figure!!

I have only known this stuff for about thirty days, so not trying to play expert here.... but you have an "early LLY" since it is a 2005. You have a few different internals. The 2006 LLY was essentially the same as the LBZ, and the ECM can be told to be act like an LBZ.

A couple of the guys here on serious turned me on to the diesel place and it has been an amazing resource. They have independent sections for each different version, so you can read and post issues related to your specific build. Here is yours:
