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.

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

    • I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt. 
    • Has anyone run these on their 2500?
    • have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.
    • Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...
    • That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
