Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

Is there service bulletin for 2017?

Have a 17 dealer did the undercoating from new plus a rust module no rust yet and I live in Nova Scotia where there's lots of winter salt

If you live in Nova Scotia and have no rust, whatever it is you're doing is working.

That's the problem with these frames, unless you strip all of the GM frame wax off, paint, then apply some sort of corrosion inhibitor...it just isn't going to work. Everything else is just band aids. All you can really do is try to slow it down...do preventive maintenance...keep that metal covered in something...and do it frequently. I actually Fluid Film my truck twice a yea - - and even then it's not enough  - I still do some touch ups when I do my oil changes...and believe  me it needs it. There's always a little piece of bare  metal exposed and I'll just cover it up with some white lithium grease (it seems to stick well and hold up). 

 

Just keep up with it, it's not a one time set it and forget it, thing, it takes some work. And that's true for ALL trucks...painted frames, rubberized coated, you name it...they all rust. It's just a matter of how much it bothers you and how much you're willing to slow the rust down. Right now my truck is only two years old...I'm still in love, but that will stop some day. I won't be so anal about treating that frame and believe me it will quickly rust. Good thing is, the frame has so much metal on it that in all honestly it will take probably 20 years to rust through to the point where you'll need repair (and you can repair these things professionally - a welding shop can handle probably 90% of these frames safely).

I live in NL and you typically see rust after the first winter, the ranchos show first sign, then chassis.

I just sprayed on flat black rust paint on spots on my 17 High Country 6.2L and it was undercoated new and has rust module. 

What is a "rust module" ?

the "new" rust modules from DiamondKote, plugin to the OBD2 port. I would suspect these are even less effective. Regardless, like High Country 6.2L/8 has mentioned, when you live in places that salt/sand are used to cover roads, and theres always moisture, and salt spray in the air - you opt for as many products as possible.

Your correct maybe rust module isnt effective on it's own or at all but the combination with undercoating helps can't hurt in Canada. Thanks for comment

np. I've used Krown protection, with the rust module, but after 3-4 years, the chassis needs to be wire-wheeled down to the metal, and a new coating applied. It is inevitable.

POR-15 is very popular around my parts. especially in a rebuild/chassis stripping project

That's what I'm afraid of after awhile. The truck is 3 years old and none yet crossing my fingers something is working. I should add it's not a work truck and I can pick and choose when to drive it.

      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

      summer road trips in the 2026 2500HD

      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.

      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.
