Well according to the manual, it has the 4.10 gearing. We both noticed something else strange in the manual. On the VIN sticker, it shows a GVWR of 9200 but the manual showed numbers higher than that, it did not have a 9200 GVWR listed. Do you go buy the sticker on the door or the manual?

I am looking at buying a used Chevy 2500hd and debating on which engine to get. This truck will get used on a farm as a work truck so it will do some towing from time to time but also as a run around

The 8.1 motor is very strong, uses about a quart of oil every 2000-3000 miles. The gas mileage is around 8-11, but when towing, it will not drop too much. The 6.0 uses about a quart every 4-5000 miles

Good point, I guess the moral of this thread is go drive them both, get the one that seems to be in better shape.

I just wanted to let you guys know that I bought the last truck I posted. If everything goes okay, I should it have by this weekend.

 

I still wonder what the deal is with the GVWR. The VIN sticker shows one number and the manual shows different numbers that are higher than the sticker. What do you go by?

What do you mean VIN sticker? The one in the door? Also the manual isn't going to be unique to your truck. It tells the GVWR for all the different variances of your model truck doesn't it. Not trying to be insulting, just want to clarify.

I would go by the vin sticker. Remember to post some pics!

I will be sure to do that once I get it.

Yes I am talking about the sticker in the door. I realize the manual isn't vehicle specific but all the GVWR numbers listed in the book are higher than what the sticker shows.

I'd definitely go by the door. It is odd that the GVWR in the book would be at all different from the sticker but hey I didn't design these vehicles. Hope the truck is a good one for you.

I would have to agree that the sticker would likely be more accurate. I can also double check for you with the last eight of your VIN. Contact me privately. Thank you.

I just picked up the truck today and here are the pics. There are a few things I want to do to it pretty soon. I am going to get the bed sprayed with line x, get some mud flaps, maybe some running boards and some new tires.

 

Sometime in the near future, I will have to replace the fuel pump since it drains back into the tank. How big of a deal is it to replace that? Is it easier to remove the bed?

Thanks.

 

I got a question about engine oil. On the oil cap, it says to use 5w30. How important is it to use 5w30? Why does it say to use such a thin oil in this type of truck?

I have heard they say 5w-30 For the fuel mileage. I run 5w-30 valvoline full synthetic and I can run 5000 mi with no issue or adding oil in an 07 new style 2500hd ext cab short bed 4x4 with the 6.0 and 6 speed transmission.

I have run the 5w-30 synthetic (mobil) since I got my truck. I fill it to about the third hole on the dipstick and it doesn't move. Never have to add any.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      Missing thrust bearing? And oil selection

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.
