Yes we know (we should) that the manual calls for 0W-20 for the 5.3 engine.

Can't remember the 6.2 oil spec off the top of my head, but oh well.

 

I'm curious what you 5.3 guys are running. Or plan to.

If you did steer of the recommended path, any issues?

Dealership will use synthetic blend mine used Quaker State........overfilled it by 3/4 quart and said, "I don't think it really matters if it's 8.00 or 8.75? So yeah, avoid the free oil change somehow

Quaker State UD Full Synthetic 0W20 or 5W20 in every car on the lot. Will also use Mobil 1 5W20 and Redline 5W30. All of these oils changed between 5 and 7 K have provided 200K plus trouble free miles

I went to autozone, or advanced auto to buy oil...... this 0w-20 was like 36 bucks for a 5 quart jug... Of course the v8 needs 8 quarts...

The bill with filter came to like 96 bucks...

 

Here's my advice - go onto amazon and buy the Oil of choice you need.... I got 2 jugs of Valvoline Advanced Synthetic SAE 0W-20 Full Synthetic Motor Oil - 5 Quart

and the bill was $48.00

Mobil 1 0W/20 can be had at WalMart - or I always watch for the oil + filter specials at AutoZone - just picked up the same oil for the 2015 Subaru Outback yesterday. $33.99 for the 5qt jug and M1 filter............

 

Oil is oil............ But when it comes to these thin 0W/20 fuel saving oils........... Mobil 1 helps me sleep at night....... :driving:

Already asked the dealership if they use the "synthetic blend" or "full synthetic" Dexos1 and they said full synthetic.......... Because I have free oil changes for life on the Silverado 6.2L on order. But doubt I will want to have them do what I can do just as easy and not have it on the crowded lot and in the hands of others.......... We'll see...........

So because 1 person had a small issue at 1 dealer they all will? Not really a F-up just an oversight, but hey I guess preach it to everyone...

So you are or aren't going to use the free oil changes?

 

Not sure why anyone would not, chances are they know more and are better at it than anyone here and if something does happen, it is documented and will get fixed (which is few and far between). On top of that it is free, money you don't have to spend! If people are overbearing just check the oil level when done, spot check the filter and plug and verify what oil they used. Not that difficult and you stay clean.

 

I have my last free oil change coming up. I am all for doing it myself (and I will) but i will miss not having to spend $50 each time and the time saved.

 

In response to the OP, what ever the dealer uses. When i do it myself I will use the cheapest big name oil in the correct weight and most likely synthetic blend unless it calls for full synthetic as I change my oil every 5k and am not worried about the extra longevity. Will do some more checking as that time nears.

First oil change at 1000 miles was done with the oil and filter I bought from the dealer the day I picked up the truck: AC Delco 0w-20 with filter.

 

The AC Delco is Synthetic BLEND, not FULL sythetic, which was fine for break-in anyway. At my next oil change, at 5k, I'll be switching to full sythetic, most likely. After that, I'll be sticking with a 5k mile OCI.

 

When I picked up the oil and filter from the dealer, the bill was $46 for 9 quarts and a filter. Yes 9, because apparently GM changed the oil capacity from 8.5 quarts to an even 8 recently and the guy who got the oil obviously wasn't aware.

0w-20 Mobil 1 full synthetic every 5000 miles in my truck and my wives 2016 Tahoe. Factory used in all corvettes for years now. 6.2 specs are the same as the 5.3 for viscosity.

      Doors lock and mirrors fold in while driving

      By BIGBOYS · Posted

      I have a 2015 Silverado and sometimes I can not get in to the truck. I use the key to unlock the driver door. Something is locking the truck when I unlock it, last night I left the truck open and this morning it was locked with the mirrors folded in. This happens while driving so it is now a safety issue. I reach down for the folding button and they open, then they close again.  Any advice, thank you,   Ed

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

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
