I would argue that the bulk def from a busy truckstop pump is probably fresher than jugs.

 

(if you are saying don't by jugs that are stacked by a fuel pump, then I'd agree)

 

 

No I’m saying buy the jugs. Lots of reported issues with the stuff at the pumps being contaminated.

New guy here...   Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.    Long post, so

When I was shopping in November, I had salesman tell me: -1500 diesel didn’t exist -it’s a duramax/Allison so it will last forever -It’s a 1500 but can pull like a 2500 with the diesel

What kind of fuel mileage does it get? sounds like way more def than the 6.6 GM's are usng.

GM 6.6's def usage is about 1.5 or 2% of fuel.

I guess I should say that it's a M2 freightliner chassis with the 6.7 cummins, so I'm sure the emissions requirements make so that the regen is performed more often. For how big and heavy the truck is it can get 12mpg on a good day and my normal avg is 11mpg.

I been making it a point when needing to fill DEF.  Turn the nossle downward before ever bringing it up to the truck.  Those nossels all seem to have fluid in them when being taken from the pump.

In my area fuel is the same price, def is roughly $25/7-8000km depending on usage, and oil changes are the same. So def and fuel filters are the added cost. $100/yr in def and 2 fuel filters, not a big deal.

thats great,  diesel here is always at least a dollar a gallon more,  and unless I have read bad information, (can't believe I'd get that on the internet?)  the diesel holds 2 quarts more than the gas.   Not saying its a huge difference, but a couple of bucks here and there adds up quick

So the price difference in fuel is the difference between premium (suggested fuel for the 6.2L) and regular. Oh wait, maybe not in your area ie. the world so that’s irrelevant. And no big deal that it holds two quarts more, you can do twice the mileage per oil change.

I guess redwngr will have to research prices in his area and decide for himself,  I'm not here to talk him or anybody else into or out of anything,  just tossing out things to think about,  oh, and for the record, I was comparing the duramax to the 5.3 because I don't think there is a comparison to the 6.2.  

It's just my 2 cents,  you don't have to agree...

Anyone seen fuel mileage listed on the sticker? Looking at them on auto trader it only has the mpg listed at 22/19. If that's the case I dont want it lol

I believe for a 4x4 its something like 19/29 and a 2x4  22/33 or something like that.

That's right. I guess autotrader doesn't have the mpg for up for the new diesel yet. 

 

I have one on order, hopefully I see the sticker for myself this week.

about .20 difference around Dallas area.  Seems like Premium runs more than diesel.

I driven my share of diesel trucks, all before the low sulfur change. Their mileage and durability was incredible. My brother and nephew continue for awhile. They weren’t as reliable after the changes. I read here that sometimes you can’t stop driving when you want to because of regen. Even in the light duty diesel. That alone would deter me.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
