Here is the manual for my 2025 it does infer that the crosshatch area should be appox 1L. and it says the oil level should be checked cold and parked on level ground. Also to check every 400miles.

My expectation for any vehicle: 250k on the original engine and transmission. Following manufacturers recommended maintenance. (I know, another argument) After that, there's not much truck left around them. Weather: faded paint, dried out rubber and plastic, hazy headlights Urban/Rural warfare: Door dings, rock chips, brush scratches, windshield chips, fender benders Road wear: CV-shafts, ball joints, wheel bearings, bushings, water pumps, seals and gaskets Kids: Stained seats, carpets, melted crayons Oops: Got in with a screwdriver in my pocket, knocked something over in the garage on it, left the windows down in the rain... It's a long road (pun intended) to keep a vehicle nice enough to continue investing in after the 10 years/250k miles.

No. A simple search on the Eaton website would have answered your question. Detroit Truetrac aftermarket limited-slip differential | Eaton They make 15 Truetracs for front diffs. Not one of them fits a GM IFS of any year range.

Impressed myself People have been telling me since I bought it that she was going to blow any minute. 200K is certainly a milestone I'm looking forward to but I have no idea how many miles it will take to quite the pessimist among us. Pattern has been; they set a goal, Pepper exceeds that goal, the goal post gets moved. At some point I'll run out of time. It is catching up with me. We'll see. 300K? 400K? Half a million? It's not using oil yet and that is a great sign. It's not leaking from any part of the powertrain. Another good sign. So...

That's certainly good to hear that there was nothing alarming on the cover magnet volume wise or chunk wise of metal. I don't recall if the Banks cover holds more oil than the factor cover, what volume did you estimate that it took ?. As to the transfer case I assume you bought whatever brand you wanted of a Dexron VI automatic transmission fluid. Have you changed the automatic trans fluid at some point and actually I don't recall if your truck is the gas or diesel version as that makes the difference as to which transmission and oil type is required in 2023. The problem with my truck is that its the gas engine with the 10 speed and I've not yet attempted to see if I can drop the pan as the silly exhaust is right in the way and I do not want to touch the exhaust system on the manifold end if I can help it, the diesel does not have the Y pipe style exhaust under the pan so is not an issue to remove the pan.

It's amazing the different ways people think. Fluid expansion has never come into play in 50+ years. If the dipstick level, oil or trans is with in the marks is all that matters to me. I have always done oil checks on a cold engine. Not saying that's right, just my way.

Update, just got ok from chevy for dealer to replace engine. But its on backorder

I know when I was looking around last year to see if someone handled Amsoil gear oil to buy at the retail level which of course means full price. I found an independent shop that works a lot on GM/Duramax pickups and they did not bring in the 75W-85 as they just stuck to the 75W-90 for the front and rear as a standard practice for the HD trucks which makes sense anyway for the higher hp/torque diesel and pulling heavy loads in four wheel drive. I haven't changed my diff oils yet but still plan on using the 75W-85 for the front diff as I highly doubt I will be beating on the truck and figured for my use type the bit thinner oil would be to my benefit for the winter for that slightly less drag. Very different weather here all winter vs northern Washington near the coast, that's for sure.

Always refuel when it gets down to 1/4 tank, especially in hot weather. Anything lower than that just wears out the fuel pump faster. And that way, you won't have to worry if you can make it to the next gas station or not.

OMG don't let @riddler see this

2024 gmc 2500hd doublecab 6.6l gas, 81,000 miles, running great

Yikes, I would have been pursuing a lemon law buyback if mine was sitting that long. "Sorry, we don't have the part" isn't a valid excuse.
