Maybe I'm the minority but I've also never had a new car burn enough oil that it was even low enough to register.  I didn't check it because I did oil changes earlier than the manual recommended and thought that the techs would tell me if I was low, as would the computer (which obviously eventually it did).

which is why I hate to trade it, but I just went out to it now and remote started as I walked up and there was quite a bit of ticking, which the dealer says is the fuel pump, not lifter related.

 

At at what mileage did it start using oil?

45k ish?  Right around there.

 

I’ve still got a bit of warranty, and I did call GM and it cannot be extended again.

 

I hate to think about trading it in, but lifters outside of warranty is what, like 9k to swap to non collapsible

Pretty much around $3.5k if you DIY is worse case scenario and that's doing a tune up and buying your own HP tuners as well.  Go browse my thread a few down from here if you want an idea of what it takes to do it.  If you drop off at a dealership its north of $10k for that.

My local independent shop said about 9k with upgraded everything, so I guess that tracks.

 

I’m looking at the auto start stop/dfm disabler, but may be too late to do any good.  (https://a.co/d/fEQxHGM this one)

 

It sure sounds like any truck from any company is a crap shoot?

 

GM has lifters 

Toyota is replacing 200k engines so far

Dodge is having hurricane issues 

Nissan is no longer selling Titans right?

Ford is, well, Ford?

 

is there anything that’s safe anymore?  lol.

 

I was leaning towards swapping to a 25 Tundra but I’m looking a bit, even if it is lifters, I may be better just keeping it.

@richard wysong suggesting the PCV system is solid. However they do not malfunction for no reason. Blowby (loss of ring seal) overloads them early and when they plug, it is as Richard states. It is a bit of the chicken and the egg however.

 

Several possible scenarios. 

 

1.) Oil control ring and or land return passages plugged/plugging. This won't show on a compression check. 

2.) HPFP or injectors leaking into the sump will tank the viscosity and break the seal. It will show up on a UOA as a good dose of GC fuels. Over 2.5%

3.) Combination of the above two wear out the bore. This will also show up as large fuel dilution and knowing which witch is which can be difficult. It will show on a compression check.

4.) DLH coating on the rings failing. Pretty much a teardown to diagnose and repair. 

 

Auto RX used as directed will free those rings. That said if the bore is damaged that may not stop the consumption. 

 

I tired dong it in steps on a 2.4 to isolate and it took so long that the bores failed even though I fixed the issues of bad pump/injectors and freed the rings and installed a new PCV system. Doing them in concert won't answer any questions but it does give you a better change of success. Replace the PCV system components. Do a UAO, @Black02Silveradocan help with that. And while you wait on the results of the labs Auto Rx it per instructions. No shortcuts. After the rinse oil change use something line HPL Premium or AMSOIL SS and go 5W30. If this works you oil or your oil maintenance program failed you. 

 

Fresh air filter helps the PCV system. Fresh plugs is a good idea and have the coil function checked. 

 

That is all I have for you sir. Best wishes.....

 

I'm not telling you this will work. I'm telling you if you don't worse is what it gets. I've nursed that 2.4 since 80K and she is limping along at 266K and been a full time job keeping her running.

At what mileage SHOULD he be checking oil level?????

[richard wysong]

It's a good idea to check it once a week unless there is a low level sensor, Most folks are too lazy to bother, myself included, the Caddy leaks oil but has a sensor so about the time it says check the oil the second time I just change it, The truck uses a quart between changes but gets checked once in a while. Again a vehicle that never sees the hi-way and does short trips not reaching operating temp for any significant amount of time should be using the severe service oil change intervals and as Grumpy stated the rings may be gummed up.Common occurance in my Caddy because even on the hi-way it's only turning 1200 rpm, GMs solution is Wide open throttle runs to exercise the rings and decarbonize, night and day difference in the way it runs after. My last Caddy was an earlier generation Northstar that burned 5 gallons of oil on a 1400 mile trip to Fla, after doing the WOT thing it only burned 2 gallons going home, GMs solution for that was replace the rings. Sold the car

I check mine at fuel stops. Unless you've been looking from day one you don't know what is normal or when it starts.

No these trucks are now made to throw away and get worse with each passing year IMO. We have already seen this progression with smaller appliances. When i was a kid a washing machine was a once every 20+ year purchase. Today if you get 5 years of use out of one, and that is top end line ones, you should feel lucky. One of the bad elements that have arrived with EV tech is manufactures will make far more money building these things to NOT last! You make them so unaffordable to repair that the only move that makes sense is complete replacement. Even better for manufactures and bad for customers is it will eventually completely eliminate the secondary market for the most part!

Depending on what’s available warranty wise with CPO I may consider leasing. If it’s trouble free leasing and I can add an extended warranty to then buy it. I may try that. I have several family members that have bought VW products. They are happy with those so far. In December they have sign and drive. I got about two years before I hit 200K on the Odyssey. The maintenance to pass 200K would finance at least 2 years on a VW lease. Probably additional upkeep on the Odyssey would give me another year in lease payments covering the VW. I don’t have to worry about payments, I just like the running the numbers for fun. And the attraction of a shiny new SUV for traveling doesn’t hurt. People are placing bets in my family on the when I’m going to get the next one. It’s approaching 2 years with the Odyssey. I usually change something every two years. I don’t have the overwhelming urge yet. I passed on two so far that could have replaced the avalanche. Didn’t pull the trigger.

I’ve had 2 Atlas’ now, and over the last 15 years 2 Passats and a Jetta and never an issue.  It’s funny that people always seem to say to stay away from them.

 

I normally don’t have this much trouble with decisions but I’m ultimately at, do I keep the Sierra, or is the oil thing a big enough issue to get out while I can and head to a Tundra or another brand.  Not sure anyone can truly answer that, but is why I’m struggling for sure.  Guess maybe the second part is what company is more likely to stand by their product?

 

Completely agree that nothing is made to last anymore!

Tundra had some problems initially with the new V-6. From what I’ve read the stepped in and took care of the problem. Now they seem fine. I know one guy with a new one, he’s very happy with it. My brother in law bought his daughter a VW SUV for college graduation. He’s only owned large GM SUVs. He’s so impressed his next vehicle will be their largest SUV.
