Loaded Bed avg: 1000 to 5000 lbs

Driving style: Grandmoma to Race Car driver

MPG:16 to 18 over here

 

still a fresh truck 5600km

 

dreaming to hit 20+ one day :thumbs:

How fast? Pretty much all the speed limits in western KS are a minimum of 65 with interstate 75. I usually run mine 4 over the posted. I think I'm going to drive mine 55 for one tank and just see what it gets to see what all this 20 mpg stuff is about. I think driving that slow would drive me insane.

I set the tach at 2000 rpms which is about 82 mph. The trip was from Arkansas to Reno Nv and back, so I had a lot of different terrains to travel. My truck is a dd that on a normal week will only see about 150 miles and I never know when or what I might be pulling next. :jester:

Update, !!! Went and did it

I was on way to order a brand NEW 2500 sierra stopped at one more dealership were a friend/drinking buddy works he hooked me up with a 2013 Silverado only option missing that I did not get was a back up camera plus side this truck is a CC as I was going to order an EC plus 20 inch wheels with rebates and low financing the CC worked out to be cheaper then an extended cab and they dealt on the truck since on the lot since spring

 

Plus and I know the truck is not broken in but the DIC is showing 19.0 to 20.0 mpg. If this is an indication that I may get decent mileage I am ecstatic I was thinking 16-17mpg

duramax pulls like a John Deere, you will forget the boat is back there if not for the mirrors and no 4000 rpm downshifts. I pull a 15000 lb fifth wheel and duramax will run 80 mph all day long.

Our 2013 2500 HD got 11 mpg hauling the 10k+ toy hauler with Polaris Ranger and water to Eastern KY at 70 mph average. Gets about 17 or 18 not towing highway. This is our third Dmax. Good trucks with good trade in.post-125555-0-00572900-1385221520_thumb.jpg

I have a 2008 GMC Sierra 2500HD Duramax Allison Shortbed Xtended cab, bought it new and use it to tow our fifth wheel. It's stock I've made no changes at all to it except for replacing the transmission cooler hoses to Alligator lines. Our trailer is 35 ft. long, weighs around 11000 lbs. empty and my guess is 12500 full of our stuff.
I have kept track of fuel purchases and mileage since I bought it, it's got approx. 67,000+ miles and in my opinion is a garage queen but I use it as a daily driver.
I average 12 - 14 miles around town, mostly 14.7 to be honest, it I do a lot of highway driving per tankful I'll see 17 miles per gallon as an average. I have gotten 22 mpg on a trip to Maine from Rhode Island.

While towing our FW I've gotten as low as 9.5 just starting out in Rhode Island on cold winter day to

11.5 the further south and flatter the terrain gets, additional info on truck, I have Michelin M&S tires and I don't exceed 62-65 while towing which is what the trailer tires are rated at.

I'm thinking about a 2015 3500 CC short bed for my next truck, it should improve my payload numbers since they are not to good with the 2500 and I feel I'm over weight for the truck.

      OCI, not when but why?

      By Grumpy Bear · Posted

      I understand. It is disturbing to think a manufacture asks so much and gives so little in engineering support. This is not a GM issues, this is a greed issue and one the ALL practice.    My intent was not to remove the wind from anyone's sail but rather to point out the areas deficient so that they can be discussed with improvements the goal. But to do that you have to know the truth and what that truth is.    The commercial interest are honed in on a few select issues in which they control all the variables and are not forthcoming in the least with their customers about the details. Failure is the only thing that drives these people to improvement. One way not to fail it to manage public "expectations". The set a bar they can clear and put their thumbs under the suspenders with chest puffed.... Only the internal data tells the story fully. As we don't have access to that for decades then we have to generate it ourselves. UOA's with data that matters.

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...
