2020 Silverado 6.2 a quart of oil every 1000 miles?

[johnnyquick]

Guys, I have frankly babied this thing and use it mostly as a daily driver for the family not as  a TRUCK.

Last oil change interval which I do normally at 30% on the indicator my low oil light came on, so I panicked and stopped and checked it thinking No effing way can it be low on oil.

Checked it after it sat for a bit and indeed it was low to the tune of 2 quarts.......so thinking somehow I have written the miles down wrong or it was a fluke etc I didn't freak out but did change it again soon thereafter.

Well driving with 2063 miles since last change the light/indicator came on and so I checked it and indeed the sob is 2 quarts low again.

Using full synthetic 0W20 with the little Dexos words on the oil container and all that jazz, not one drop leaking anywhere and just under 47K miles on it.

WTH is this? I am 58 years old born and raised on a ranch and farm with equipment and all sizes of vehicles around.

This uses as much oil as anything I have ever been around.

Anyone have any input on this?

I am thinking dump it and get something else or put the Z06 engine and tranny in it, what a waste of a nice looking truck.

Still under warranty til 60K but I am certain GM will say it is normal.

unfortunately you will have to waste your time and do their oil consumption test and then they say its normal. love my truck but hate gm service and parts departments

Thanks will try to get consumption test done.

That is terrible. Make the dealer do the f***in oil consumption test and if its more than 1 qt per 2000 miles make em fix it.

Likely the culprit.  Gotta send it here and there early on to set those rings nice.  Ramp up load and RPMs in the first 1500mi, getting to a couple good WOT pulls at that point, then dump the oil and follow whatever regular oil change interval.  

 

Rings don't seat good?  Oil consumption happens.

That's what I was gonna say but decided to keep my mouth shut. You baby it and it's not going to end well. Engines have changed DRAMATICALLY since the 50's-80's when you didn't want to really beat on engines when new. This video has a lot of good info in it:

Knock on wood I haven't had any of my new trucks consume a drop of oil or no more than a couple ounces to a 1/4 of a quart in an oil change.

Great info but the oil control rings are highly influential on fuel dilution influenced stock engines even brand new ones. The FUEL additives that are polymeric and cook from day one especially heat and cooled using AFM will clog with that damaged polymeric blowby and must be cleaned somehow. Or you use oil. I’m betting you have a factory defective coil or coils or sticky injector/s causing that build up and those cylinder/s are what’s sucking the oil away.

In my 2.7 L3B 2022 LTD #3 is doing just that. When I clean the injectors with Black02Silverados Amsoil PI he set me up on preferred account it stops the oil usage dead. I also have an alternate oil I’m using but i. The 6.2 case stick with 0w20 engine oil.

Note #2 and #3 are almost always deactivated on 2.7 engines unless accelerating or pulling hard or in L manual  shift mode and not in 8speed cruising.

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.

I half throttle my rides at least at take off. Just barely below the traction control intrusion. I like the sensation of speed. I don’t go over the speed limit. I just get there quick. The one most people don’t expect it from is pretty fun. The odyssey, I had no idea it was so quick. I have one road that’s full of lights, has 4 lanes and a 60 mile per hour speed limit. It’s on the way back from my walking track. It seems Ram drivers are the most aggressive. I love surprising them with the Honda. Once they catch up we’re at the speed limit. My wife’s Genesis is the fastest of my 4 and a hemi killer, you’d never know. My brother had a 2010 challenger. We used to line up new rides for the test. The Genesis-Hemi Challenger race in 2011 was a surprise for everyone. I later bought a Genesis coupe instead of a Hemi Challenger as my mid life crisis car. I can floor my avalanche all day long and wouldn’t get in any trouble. Especially since it’s the first without loud exhaust. So as I make my way to the 200K mile mark it will be interesting to see if my break in process or driving style is detrimental.

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

Towed my landcruiser home across highway 2 from Kalispell MT straight from dealer, I do plenty of accellerating etc by babying I meant no abuse of the vehicle, I have not overloaded it, ran it up and down gravel roads, no potholes, no uber or bs like that.

Took it to dealer and getting the Excessive oil consumption test documented, but I already know by checking my records that I am using twice of what is considered the excessive amount so will have to run their miles and see what they plan on doing.

No idea what that may be as they are likely to inept to figure out where the oil is going. But will keep everyone posted.
