That's weird. AFAIK, the engine oil capacity was already specified at 8.0 qts.

In my manual it says 8.5 and sometime last year I believe it was a bulletin or something came out saying it was down to 8 because 8.5 would show on the dipstick that it was too much. I almost want to say that the dipstick is just marked wrong and it's cheaper to just put 8 in instead of making all new dipsticks. Being 8 qts a 1/2 quart won't matter so no big deal.

My guess is the interior volume of the engine was calculated on paper to measure 8.5 quarts of oil technically but the sweet spot is actually just 8 quarts.

 

I don't agree with the mislabeled dipstick theory. Dipsticks are cheap to replace and if it was just a mis-labeled dipstick, GM would implement a production change on the dipsticks for the trucks made after the discrepancy was found and simply replace the dipsticks in the trucks that had the wrong ones. The main thing at the the end of the day is to have the correct amount of oil in the engine and a revision in the oil quantity seems more likely to mean that 8.5 quarts is too much oil for these engines.

 

For what it's worth, when I had my BG service done at my side mechanic, he had to change the oil after the service and the truck took just under 8 quarts of oil to read correctly on the dipstick.

#PIP5231A: Concern of engine oil dipstick indicating an overfill - (Oct 9, 2014)
Subject: Concern of engine oil dipstick indicating an overfill

 

999999995.gif Models: 2015 Cadillac Escalade 2014-2015 Chevrolet Silverado 1500 Suburban, Tahoe 2014-2015 GMC Sierra 1500 Yukon with engines 5.3L, 6.2L RPO's L83, L86

This PI was superseded to update Recommendation/Instructions. Please discard PIP5231.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern

The Engine oil dipstick indicates an overfill when performing a PDI or after an oil and filter change.

 

Recommendation/Instructions

Typically you will find the dipstick indicates an overfill of 1/2qt of Engine oil.

 

There is no need to drain the oil at this time, as this concern will not damage the engine nor affect operation.

 

When it is time for the oil change, fill with the recommended amount of engine oil as specified in SI

SI has been updated with the engine oil (with filter) fill specification of 8 quarts or 7.57 Liters for 5.3L, 6.2L RPO's L83, L86 engines in the models lists above.

 

Note: The correct “full” mark is the upper dimple and the “add” mark is the lowest bottom dimple on the Engine oil dipstick

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

I take this to mean that even with 8 quarts, the dipstick will still read over full.

Shouldn't....the issue is if you put in 8.5 quarts it will read over full,but with 8 it should not.

I have just under 8 in mine and it reads over full. It's just not AS over full as it used to be. Also if you read that bulletin, they're saying that it's normal to read overfull and to still go ahead and put the recommended amount of 8 quarts, not reduce it to 8 quarts from 8.5 in order to get a correct reading. I dunno maybe I'm misunderstanding it. It's not written very well haha

On the previous generation GMT-900 models, the owner manual said the oil capacity was 6.0 quarts and to check the oil when it was warm. If you checked it cold, it would show 1/4 to 1/2 quart overfull. But if you checked it warm, it would show right on full because some of the oil was still up in the engine. Maybe this is the same situation here. Wonder why they went from 6 quarts to 8 quarts capacity from 2013 to 2014? So the AFM motors could be low and still have some oil in them??

These are completely new engines from 13 to 14 MY.

 

Cooling and longer change interval.

As already mentioned, they're 2 different engines. The 4.3, 5.3 and 6.2 in the K2s are all newly designed engine. And more QTs means less often the oil is being run through the engine so it last even longer.

      Thrust bearing is a very small window.  But nice try.   Turbo oil filter?  Haven't seen any failures.  Change your oil more frequently.  Use a better oil than the factory oil.

      There is a p/n called out in the one PI that GM has.  Curt 57003 inline load adapter that is used for LED trailers that are having trouble with these newer trucks.  No cutting, no splicing, etc.  GM did update the lighting module around 2023 to better pick up trailers with LED lighting, but it still can happen.     Here's the link to the Curt site for it - 7-Way RV Blade LED Electrical Adapter (Not a Wiring Extension) SKU #57003 by CURT   The PI I am referencing - MC-10208985-9999.pdf   Its not just a GM deal either.  Newer Fords and Rams have this same problem.       In another PI, they recommend that the trailer has a Pollock brand 7 way on it as that is who makes the truck sides for the OEMs.  GM is also big on making sure the trailer is trouble free.  So no wiring issues, all lights are functional, better quality 7 way plug, etc.     The other PI I am referencing - MC-10178359-9999.pdf   The model year range is older but it is the current PI for 2014-2026.  It calls out the Pollock RV HD 7 way they recommend.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      That's part of the problem...the EGR has already been replaced, and I've already had the complete intake assembly removed, and the EGR passages were clear at that time. That leaves wiring, PCM, or another variable that I wasn't expecting. Best I can tell, it's not wiring or the PCM, so I'm grasping for straws.   The PCM uses the MAP reading to confirm the requisite loss of vacuum in the manifold when the EGR activates. Since that's vacuum related, it involves a lot of other systems which could play a role.   The overall diagnosis has to be considered too. The fuel lines in the intake had rubbed through and were dumping fuel into the intake, drowning the cylinders in fuel, and putting raw fuel into the sump and cat converter. The fuel system has been fixed but the complete path of damage may not be. If the cat was damaged and melted the internals, it could be partially obstructed and also playing into the EGR issue.   I'm retracing my steps; trying to go back to thinking thinking Horses not Zebras based on the clues I've been given. These engines aren't *that* complex.   Could it be, now that the truck is running well, that carbon and crud from being run with the fuel system in disarray is now dislodging and clogged my clean EGR passages where I can't see?  That's what the code is actually saying. The flow is restricted, dummy. Retrace step 1.   I may just need to remove the lower intake again. Before I do that I'm going to try removing the EGR and running the engine for a few seconds to see if it will blow anything lodged in the egr passages out through the open ports.     That's been helpful in the past. For the spider injector, there's no guarantee I'll get a working one. The spider I have seems fine now that the high pressure fuel line isn't making an early delivery via large hole. SO at least I'm not marooned and looking for one of those.   Row52 (dot com) is also a good one for watching for vehicles at local yards.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Disassembly may be Required!   Every blender makes claims but do  you ponder those claims? What was really said? Was it true?  Motive for saying it? What does in infer?  Is that inference true?    Let's do one.    Claim: Made from shear stable base oils.    What was said: Base Oils are shear proof.   Was it true: Yes.  ALL base oils are Newtonian.    Motive / Inference: To imply the fully formulated product is Shear Proof.    Is the Inference true?: Most fully formulated multigrade oils contain Viscosity Modifiers or VM's, sometimes called VII or Viscosity Index Improvers. There are four types. One is in fact shear proof but it also has a bad effect on extreme cold flow and is restricted to use in specialty oils. A second has limited shear called a 0-5 SSI polymer. Meaning its shear is limited to a range of zero to five percent as reported by the ASTM D6278 Shear Stability Index test. A few high end oils, like Torco SR-5, use them and brag about it profusely. Actually all that use it point it out. The last two shear dramatically and are often marketed as a 'feature' of the product aiding the oil to meet fuel standard requirements of ever stricter rules. One shears more than 5% and the other up to 20%. As you make guess, cost is directly linked to shear down and as such the majority of oils use the cheapest organic polymers sold to make grade and pass stringent tests.    PPD's or Pour Point Depressants also shear a bit, only a few percent and hide inside the 0-5 SSI capabilities.    The blender knows he can not out engineer Stribeck. Physics is not a suggestion. But he can wordcraft the unsuspecting toward believing a false claims INFERENCE. This is LEGAL. It is COMMON, and it is EFFECTIVE.
