My Oil change light never comes on. I always change oil every 5000K, and it has never come on so far? When do you guys change oil and when does your light come on?

Thanks

Mine comes on between 6500 and 10,000, depending on the time of the year, what kind of driving I'm having to do for several weeks (some weeks are mainly low speed, some weeks are mainly freeway).

 

The 3,000 mile mantra is DEAD. No more. GM and other manufacturers are recommending to use the oil life monitor.

 

Your manual recommends using the monitor. There are a lot of flame wars on the other boards about this. So, rather than my stepping in this old issue, here is a link to the General Motors site that explains their recommendation:

Mine's come on 1 time in the year I've owned this truck. And it was right around the time it was due for an oil change. I change my oil approx every 6,000 miles; I drive 5 days/week on the highway and mixed driving on the weekend.

I did my initial oil change at 600 miles to a cheap 5W-30 and a PF-59 to clean the build shavings out; reset the OCI. At 1,200 miles, changed again to Mobil 1 0W-30 and PF-59; reset OCI.

 

Generally, from that time on, I've only changed the oil (Pan drain) twice a year: Mobil 1 0W-30 winter and Mobil 1 10W-30 summer. I change the filter when the Message Center scrolls CHANGE ENGINE OIL.

 

FWIW: the inside of my oil filler cap is SPOTLESS. Clean as a whistle. I average about 4,200 miles per quart running Mobil 1 0W-30 and 6,800 miles per quart running Mobil 1 10W-30.

 

If I lived in a more "moderate" climate (Warmer than 0 F most of the year) I'd run Mobil Delvac 1 5W-40 all year round.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
