Riddle me this.

The "check oil level" warning shows up on my dash. I get out and check it and the dip stick is dry. I look all around the top, sides and bottom with no signs of a leak. Where did my oil go??? Now I'm walking to the parts store to buy more oil.

I found out where you live and siphoned it out...

Sounds like the typical 5.3 oil consumption issue. How long has it been since your last oil change or since you last checked the levels?

 

[Goodinblack]

That's crazy.

Need you to keep better tabs on this thing. Still under warranty?

 

[dropmech]

I thought we were friends Nate! It's the 4.8 and it's only about 3200 miles into the last oil change. I normally go 5000 because 95% of my driving is highway.

And no warranty. 140xxx miles on it. Haven't had any other issues.

Have you noticed oil consumption prior to this?

 

[dropmech]

Nope. This is new. I'm a little concerned. I don't check it every time I gas up but some times I do. Never noticed anything out of the ordinary.

Do you change your own oil? Could it be possible that you might have shorted yourself a quart on the last oil change? My denali is usually a quart low by the time I do an oil change and that's usually after 4000-4500 miles into the oil change! If you were a quart short from last time then that would make sense why it doesn't even register on the dipstick.

 

[dropmech]

The last time the oil was changed, Chevy did it. I normally do it myself. You mean to tell me that if it's only one quart low it won't show on the dipstick and I'll get the warning on the DIC?

I think it actually requires you to be 2 quarts low before it starts not showing up on the dip stick and the warning shows up on your DIC

I've been having this same issue in my 6.0 hybrid motor. I think it's related to the PCV valve issue as well. I just put on a new valve cover that is supposedly redesigned and so far so good. I had the dreaded white smoke upon a cold startup occasionally as well. Last few oil changes they said it was really low. I keep an eye on the level every time I fill up now.

It ended up only being just over a quart low. I haven't had any unusual smoke or any other symptoms. Just gonna keep my eye on it.

This oil consumption issue is a well known problem with the GMT900 platform. If you bring it up to your dealer, they will do a test on your car and make you bring it in every 1000 miles and check your oil. My dealer had me bring in this sheet to them everytime I came in, but unfortunately I was too lazy to bring it in every 1000 miles and never finished up the testing, then moved 1200 miles away. But there are a lot of people who have done this same test and the dealer has indeed fixed the issue. I do know for a fact mine is constantly saying it's low on oil and it is an issue though...

A lot of my friends have NNBS silverados and they have the same issues , The test that GM does is called the Oil Consumption Test , and while every engine is supposed to consume a set amount of oil every 1000 miles there are limits . if your tests exceed these limits the dealership is supposed to fix the issue if it is a known recall . However to my knowledge GM never sent a recall out . but they will repair it if it has a warranty

Oil consumption tests are common in Factory Forced induction vehicles while its under warranty. My chevy cruz consumes about a quart every change 7500 miles
