Oil dipstick?

I have the 4.3 L V6 Silverado that calls for 6 quarts of oil. However, if I put 6 quarts in the truck it seems to be well past the full “waffle mark“ (crosshatch fill zone)on the dipstick. It actually almost goes up to the point where the dipstick reader and the wire connect. Seems awfully high. However, if I put 5 1/2 quarts in it, it almost reaches the top of the waffle impression.
 

and yes, I completely emptied the oil and drained it on a flat surface. 
 

in fact, when you read the dipstick with 6 quarts of oil in it, it’s almost hard to tell that the oil is actually going well above the top of the full mark of the dipstick because it tapers off at the top. If you hold it in the perfect light, you can tell that it is well above the waffle mark
 

Anyone else notice this oddity in the dipstick reading?

Seems that way on most new GMs.  Most find that if they follow the instructions in the owner's manual (run the engine to normal operating temperature, shut it off, let it sit for a couple of minutes, then check dipstick, wipe, and recheck) that it is closer to the full mark.  If you check it cold, it looks overfull.  I worried about that at first, then at the advice of my GM service manager, I have just been glugging in however many quarts of oil the owner manual says when I do an oil/filter change, and have never had any problem over many years now.

Also the pan never has 6 quarts in it while running anyway because there is 1-2 quarts being pumped though the engine and falling back into the pan at any given time.

This is a bit off topic, but Does your oil pressure increase with RPM?

My van's pressure guage shoots right up when the passing gear kicks in?

      Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.

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

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.
