2020 Silverado 6.2 a quart of oil every 1000 miles?

[johnnyquick]

PS when I picked up my truck originally it had like 6 or 10 miles on it but a large number of hours in comparison and I was already home so I did not think much about it.

I found out later that Chevy new that they had some crappy issues and were having dealers put large fans in front of the trucks and run em at a high idle for X amount of time to see of they acted up.

I will search for that information.

Thanks for any and all input.

Are you saying that just recently it started this and for the first, say, 50,000 miles it was fine?  

Last oil change it came up, but I was travelling alot and added oil and kept running her thinking WTF but did not check records until I was into this oil change only 2k miles and it came on again so for the first 40K it was good to go.

My 2019 with 48k on it stays full.  When I got it brand new, I drove it like I did with any of my other vehicles. No break in, just got in and went.  The fact that the 6.2 has so much power, it was hard to keep it out of the redline.  

 

Anyway, I changed the factory oil out at 500 miles, installed AMSOIL's OE 0w-20 and went to 1,500 miles, again with the OE 0w-20 and then went to 3,000 miles. Then installed AMSOIL's Signature Series 0w-20 and now following my used oil analysis for changes.  Currently going 10k on a change.  No oil usage at all.

 

Now I do drive in manual mode and select L9.  Have been since I purchased the truck.  This keeps auto stop and DFM off.

 

I also run a bottle of AMSOIL's P.i. every 4k miles as well as mix E85 fuel in with regular.  I fill 10 gallons of E85 and then fill the rest of the way up with regular or premium.  Have been doing that as well for over 40k miles.  No issues.  I want to convert it to flex fuel but for now the cost isn't worth it. Hoping down the line that cost will go down. 

My 2020 has no E85 sensor so I run premium only either 91 or 92 depending on where I am at geographically.

I am using a Pulsar so no auto off and on or cylinder deactivation is occuring. Oil changes always at 30%ish with the 0-20 Dexos

I think the above poster with the fuel dilution idea may be onto something, but i am going to wait and see what the clowns at the circus come up with first.

I expect a jerk off session from the Dealer and or GM but I am prepared for the battle.

Truck is gorgeous, I have expelled the whole thing since it's first week and done exhaust and wheel and suspension upgrades to it blah blah so this sucks to have to deal with.

Stay after your dealer and don't let them beat you down.

 

Good luck.

Pull an oil sample and have a GC fuel run on it plus 100 C viscosity. If vis is fine and fuel is low, then at these miles lacquered rings would be my next best bet. Rings don't just 'unseat'. They stick. But make sure it isn't viscosity break first.

Where can I get the oil sample tested and how much will they need?

Ever wonder why GM calls for 5w30 in the LV3 and LV1, even today? Why 0w40 in the 6.2 Vette engine? That ought to tell you something.

See @Black02Silverado and ask for an Oil Analyzers sample kit.

Comes with instructions and he has everything you need.
