Calling all 2500hd owners

Hey guys... I've been looking into buying a GMT900 2500hd. I like the lines and i need something to pull a travel trailer. I've been looking at the 6.0 trucks. I can't afford a duramax right now. I was woundering how owners like them. I also wanted to know what kinda mpg these are getting. I've heard they get better than the last gen trucks, but no numbers for sure. Any help from you guys would be great.

i really like my 04.5 and yes its a duramax and i understand not being able to afford one, everything is expensive on this thing but worth it IMO and i sacrificed getting a GMT900 so i could get a D-Max worth it IMO but if your not towing much (weight) or heavy load not very far the 6.0 does good just no awesome turbo noises :sad: also one thing to look at i have a 04.5 and my warranty just went out on it if u find a low miles 05 06 for cheap with a D-Max you will have a warranty i dont think the 6.0 had 100k warranty

An 07 GMT800 would have a 100K mile powertrain warranty with no deduct where as the DMax has a $100 deduct and it's technically only a diesel warranty, doesn't cover the front axle, transfer case, transmission, rear axle or even all the stuff bolted on the engine. The DMax costs a lot more to maintain properly and burns fuel that costs a lot more (although it gets better mileage the fuel cost is still higher than a 6.0). If you are pulling 3K+ more than 50% of the time you need a diesel, otherwise only get one if you REALLY want one AND can afford it. The 6-speed auto is only in the GMT900 body. Never heard of a 2500 with a 6.2 but I guess anything is possible.

I'm not sure what a GMT900 is, but I have an 03 GMC 2500HD Crew Cab w/ a 6.0L turning 37's. My gas mileage is crap. 10.6 Daily, about 13 highway

i almost take offense to that lol!

no but seriously it doent cost much more to maintain, my oil change still only cost $30. diesel cost less then gas around here and i get MUCH better mileage then a Gasser and WAY better then a similar power level gasser would get.

as far as the 6.0, its a great motor too.
05-14-2009, 09:29 PM

Oil change is twice if not three times more. Fuel filter costs twice as much and needs done 2 or 3 times more often than gas. Diesel is $.20-.30 more per gallon here. Easy choice.
05-14-2009, 09:36 PM

that depends a lot on what oil you use. fuel filters do add to the cost a fair bit. but overall i get so much better mileage it still ends up cheaper. what 400-500whp gasser gets 17-18 mpg city? i dont even know what i get highway but its got to be +23.

depends what your doing with the truck. once you start puting go fast goodies on the gas truck your mileage is gona suck, i can have my cake and eat it too.

GasGuzzler

I even said it matters what the truck is for in my 1st post here.

At only 18 MPG the cost offset of the MPG still favors the gas engine.....especially when the cost of buying a diesel and modding it comes into play vs. gas.

Plain ole GM bulk diesel oil change is $50 vs. $20 for a gas engine. Fuel filter is $50 that needs replaced every 12-15K miles vs $25 for a gas that needs changed every 30-40K miles.

A dmax auto truck is $12K more than a 6.0 with all other options being the same.

yea it really depends on the circumstances, a new truck is obviously gona be a huge difference in price. if your the kinda guy that takes it to the dealer for an oil change, probably a good bit more expensive there too. also depends on local fuel prices and what power level/mods your comparing. my truck was cheaper then most pay for a decent gas rig, and i only have a little over $1k in performance parts so it makes sense for me.
05-14-2009, 09:55 PM
GasGuzzler

Yeah....also at the dealer level you'd see the people that pay so much more for the DMax that they ignore all maintenance and are usually the most likely to complain about prices and cry for warranty not realizing how much more maintenance they should have done to a diesel that they did not do because they were used to a cheap and low maintenance gas engine Long sentence LOL.

yea a guy that lived down the street from me sold his cummins because it got like 11 mpg, it had like 40k miles. i asked him if he ever changed the fuel filter, he said whats that? lol. same guy that blew up an envoy from never changing the oil. it lived and died on the break in oil! lol. some people cant handle maintaining a vehicle.

You need to get Nathan to fix the max tire size in the BCM and then we can finish tuning yours.....Nathan you need to get this fixed for him if you can.We are getting service brake system messages because of the tire size!

Man i get 14/17 easy (without Lean Cruise) , with cam (1500 HD , 6.0L) , VE still not tuned yet , of course that is running MAF , going SD (Custom OS) after I play with MAF for a while and Lean Cruise .

Not the BCM Dale and not with GM software. I can tell the ABS we have bigger tires but it won't change the engine and trans stuff as the VSS goes to the PCM before it relays the info to the EBCM and the IPC. Service Brake System means something different than an ABS light or Service ABS message. If I can make it out to the dyno day I'll bring a CANDi and a TechII.....as well as my POS MTD leaf blower that seems to have no spark. I need help as well....
