2015 Suburban 5.3 Ecotec
Out:Supertech 5W20 Dexos and Napa Proselect 27045 with 15k miles on oil and filter. I was the last one to change it 15k miles ago at 53k miles they neglected to tell me it was due till it had 68k miles.

In: Supertech Dexos 5W20, Pronto PO2500 filter
Drain plug 18 ft lbs

Despite going 15k miles, the drain pan seemed to have 8 quarts in it when I drained it.


Have any of yall seen any cases of neglect regarding the new 5.3 and 6.2 GM Ecotec engines? The info above is one I posted in the "post your latest oil change" section yesterday. Although I don't know if any damage was done, it was still running fine with no unusual noises. I saved the filter and will cut it open soon. Opinions please. Has anyone gone 15k or longer on an oci in one of these engines?

A friend did 15-25K OCIs with M1 5-30 in his 1999 Silverado 5.3. He sold it with 350K and the engine still performed very well. Reason: Third trans failed.

I have 115,000 miles on my Sierra. OCI's are usually between 7200-7500 miles (following the OLM). I have used nothing but Mobil 1 after I starting changing the oil myself. Mostly AFE 0W-20 but have ran EP 0W-20 and now I have high mileage 0W-20 in (just changed last night). Engine has been solid.

Water under the bridge now, anything you read here will be a guess. My guess, is you probably did little to no damage if the oil level was within the safe range when you drained it. I would do an oci half of the recommended interval to clean it up a bit, and then continue with the normal oci going forward.

You should be fine. Go back to your normal OCIs

So the owner/operator ignored the change oil soon, then change oil now message for over 7500 miles?

WHY? Nice vehicle, it is a shame to neglect it.

Who owns this vehicle? Is it Family or? I'd guess no real harm was done other than some extra wear running depleted oil.

Using a high quality full synthetic oil and a premium filter (choose your brands, everyone has their favorite) how many miles for a OCI?
Too many variables to list, just a ball park mileage for most any vehicle and driving type.
Yes, I know a UOA is the only sure way to know.
Would be intereting to see a UOA on the OP 15K oil.

6000?
8000-10,000?
10,000 + ?

Cut open the oil filter!!!!!! That's what I would want to see! I wouldn't run a proselect for 15k miles but it probably didn't rip like a "TearOlator"

If it was conventional oil yes; with 5-20 Dexos, not a problem.

Should be fine. The oil was worn out most likely but there was oil present and thatís the really important part.

Iíd consider a short oci around 3k to clean but itís not necessary

I saw a couple 0w20 UOAs a while back for 15000mi, probably on SilveradoSierra forums. They used AFE and EP Mobil oils and had some tbn left. Blackstone gave a good report. I don't know if Supertech dexos is quite that good but I doubt it's that much worse.

The Chevy truck engines were redesigned in 2014 and are now Gen 5 instead of Gen 4. They have a more sophisticated oiling system. At idle itís low pressure and then pressures up at highway speed to a much higher pressure than the Gen 4ís. It actually has an electronically activated solenoid involved. The AFM system was redesigned as well to be more reliable. Everything is designed to work with the Dexos oils. I guess reliability is not proven yet as the engines are only 4 years old. Maybe the Bitog truck owners can report in as each milestone is achieved ie: 100K, 150 K, etc.

The Gen 5 engine have been very durable up to this point with a ton of track time on some Camaros & Corvettes. 4 AFM lifter failures to date at my shop.
