I don't know how to say this politely, better yet why should I. If your low oil light came on you need to change your mode of operation.

Mine burns excessive amounts of gasoline.

While I have never approached things like an engineer would, I have just kept motors in an as new condition and changed the oil and filters. I do applaud the science part but never used it and never h

Ok fellas, I've got a 2021 Gasser, just took in for an oil change (every 5k) and, they told me she wasn't even low. And, we've been on 5 camping trips during this 5,000 mile stretch. We haul an 11,000

Of course it’s good to check oil. Keep in mind that the low oil level light came on long before any damage could happen. I would expect all vehicles would have such a warning light. Probably over half of drivers today couldn’t lift their hoods. You would expect at least your vehicle would be able to make an oil change without adding oil. Even if you use a qt every 2500 miles.

Who is this referenced to? To clarify, my oil light did not come on in regards to my recent post. Please elaborate on "mode of operation". No need to be polite, I am not easily offended. My goal is to get other people's perspective and learn. let me know your honest thoughts

My mode of operation is frequent oil level checks. I do 4K mile oil changes and my oil gets checked regularly. If you're looking for a number, at least once a week or the morning after a long day of driving. More often than not.

Totally agree, more frequent checks is something I will be doing moving forward. I am curious about long term durability. Thus far the truck has been great! a couple small hiccups but nothing that would make me second guess my purchase. 4k oil change intervals seems very frequent. Conventional oil is recommended at 3k, I was under the assumption that full synthetic can go way longer. While I dont agree with the "advertised" 10K oil and oil change, I usually change when the oil life indicator is around 10%. This puts me in the 6K range. However, if i'm adding 2 fresh quarts of oil every few months, that's pretty much an "oil change" by default. lol

This may be a player. I checked my oil yesterday and it was full. I did 5 checks and 1 showed 1/8 low. No doubt the OP is seeing consumption but the L3B 2.7 might be hiding oil.

The 4k oil changes are for a 19 Hyundai Santa Fe that specifies 3750 mile changes for severe duty which we fall under.

That’s because it had that gdi 3.3 right? We had a Kia van with that engine and that oil turned black in about 3k miles! I’ve never seen anything turn oil black like that. It was new too.

I can't help but wonder if the dealer put the correct amount in during the change because that's a lot of oil consumed.  Did you check it right after they changed it to make sure it was at the top of the dipstick?  Probably a dumb question but again, that's a lot of oil being used on a 28k mile engine if they put in the required 8 quarts.

This is a real possibility with the caliber of techs changing oil. 
 

how many quarts does a 6.0 call for? Because I’ve seen multiple times they will fill it to the spec of a different engine that they change more often.

The engine we are talking about is a 6.6L gas engine (rpo code L8T) is has replaced the vortec 6.0 and calls for an 8 qt capacity.

I know that. I’m implying that it is not uncommon for a tech to inadvertently pump the amount of oil based off of a different spec i.e. the 6.0.  I had that exact thing happen to me before and have heard it happen to others as well. 
 

edit. Just looked. A 6L takes 6qts. Easily possible only 6qts went in at the dealer. 
 

most of these techs don’t give a damn about engine size and which engine is in which truck so it’s very likely it happens a lot.

Gotcha! That's definitely a possibility. I personally do all of my own oil changes. I wouldn't even let them do the free oil changes.

I have about 10,700 miles on mine. It has not burned any oil thus far. I think something must be wrong with mine. From what I am reading in this thread and according to GM, it is normal for the 6.6 to burn oil. Something is abnormal with mine. I should make an appointment ASAP to see why mine is not consuming oil.

Go in there and get reallll close to the service advisor and slam your fists on the desk and say “why Isn’t my truck biting oil gat dang it” I demand you make it burn oil or I’m not leaving here. You’ll be fitted for a straight jacket ha

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      By TrueBlue · Posted

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.
