2019 Silverado 5.3L Engine Oil Consumption

[DCChevy]

Have any of you had issues with your 2019 Silverado 5.3L engine consuming oil? Mine consumed 3qts during this last oil change cycle. The Chevy dealer stated that 1qt of oil every 2000 miles is acceptable in GMs eyes. I only have around 50k miles on my engine and I am on my second oil consumption test. Any thoughts of what I can do next?

Normal? Not even close BUT that is the point they 'normally' consider doing something about it.  

 

So, how long is your 'normal' oil change cycle? Need a reference point, right?

I went based off of the oil change sensor on my truck so I was around 6,000 miles for this change and had about 20% left on my change. I had Mobile 1 0W-20 Dexos approved oil and used the AC Delco oil filter.

The Frankenstein engine may be different. I had two oil burners. A 99 Ford 4.6. Every 2500 miles. At 20K I put a S/C on it. At 130K I traded it in. Never burned more than that. A 94 Z-28. Same burn. My wife put 60k on it. My 17 year olds first car. Another 60K. My toy I put 30K on it. I beat on it. Never used anymore than that. Hope that makes you feel better.

So your at the point it is not good and they don't care to help you. First things first. Not leaks external nor INTERNAL, right? Second things second. PCV system in good shape? 

 

If those check out the likely source is what they call, "collapsed rings". Read that varnished ring lands holding the rings in preventing seal. You have some miles on your warranty? Did you buy an extended warranty? They will try to run this past the miles of that warranty if it is close. Sad but true so get it on record now. 

 

There are two methods they have access to. A top end soak to attempt to free the rings. Re-ring the motor. The soak can help and if it does slow it enough to take you out of warranty. I've got one right now that was out of warranty that got to a quart in 600 miles that I've nursed (soaked) back to a quart in 10K miles or so but sir...it's rare. I caught it right away and did somethign about it. 

 

IF you get them to re-ring it then learn from your experience and don't think your going to get a Dexos 1 Gen 2 oil past 3,000 miles OCI. Sucks yes but there are cheap oils that are good oils you can change at that rate and not break the bank. 

 

You can also trade and just learn from this.

 

That's all I got...happy hunting.

I have a 2019 Silverado with a 5.3 motor that is utilizing at any rate a quart between oil changes. The engine has around 37,000 miles on it and I've replaced the oil about 15% on OLM each time with 0W-20 Shell Rotella Gas Truck.

My 2019 Silverado 5.3L is doing the same. I get 1500 miles and my oil pressure low light comes on, I check the dip stick and I'm already down 2 to 3 qts low. I brought it up to our dealership last month when I went in for yet another oil change and they had me log my readings every time I filled up with gas. Took it back last week and they did an oil consumption test on it and low and behold they told me it was consuming oil. Hmmm. They are keeping the truck until they can find out how and where the oil may be going. I overheard another consumer telling the service department about the exact same issue on his 2019.

This will not fix the excessive oil usage and has nothing to do with it. Not since the release of the Ecotec3 motor platform. This is about stuck oil rings. Rings stick because the oil oxidizes creating solids and varnish that stick the rings in the lands and they no longer seal well. The oil oxidizes because it is forced to run to hot and for to long. Even 5,000 miles on a standard Dexos1Gen2 oil is to long. As long as people insist it should be 'other' they will continue to have this issue. Do not look to GM to back this idea or you. Lower your OCI to 3K. 

 

Fixing it it tough.

Avoiding it is easy.

Use a better oil and change it more often. 

 

I've had some success with the GM top end soak. I have one motor back from a quart in 600 miles to about a quart in 10,000 miles. This motor lived on a diet of QSUD on 5K OCI's and still failed. 

 

I have another that used Red Line HP and AMSOIL now at 142,000 miles that doesn't use anything measurable. 

 

However I will be trying a new product very soon. TRIAX S7 is a detergent package claiming to free stuck rings. I'm going to put that to the test real soon. We tried the GM top soak. Helped. We tried BG EPR flushes...meh. A few other flushes Nope. I'll get back to this later.

Low friction rings = drive it like you stole it a couple times a day when its new.    

 

I think long drain intervals, excessive heat strain on the oil during that period and lots of engines that idle too long or don't ever get driven harder than 2500-3000rpm "babying" it.  

 

My 2019 (old body but same 5.3) burns zero oil at 33,700 miles.  First 1500mi I ran a gradual engine load and RPM increase, at 1500 I gave it some WOT pulls, then drained the oil.  I change every 3,000mi and see WOT not quite once a day but close to it (tuned E85).  Even then zero loss, no fuel dilution so no fuel is getting past the rings nor is any oil.

Did you look at Valvoline's Premium Blue Retore?  It was specifically formulated for Cummins.

I did not but will give that a look.

Thanks for the heads up Nick!

5.3L and 6.2L with oil consumption issues. Check your valve seals, if cracked this is the cause.

I have around 104,500 miles on my 2019 Chevy Silverado.  Last 2 oil change cycles with around 30% oil life remaining my low oil warning came on.  I use the 0W-20 full synthetic and had to add a couple of quarts before my oil change.  I notified the dealership where I get the oil changed of the issue, and they said to let them know if it does it again. Well it did, and now I have an oil changed scheduled and they are going to run a pressure test, and dye test when they change the oil.  Hope they can figure out what is going on.

Did you laugh when they said this? I did when I read it. Not self-healing.  I for one await the results and hope you come back and post it up.  Please....
