I haven’t had but 2 oil users since the 90s. Even those two would go to 5 to 7K oil changes without getting too low. With all the sensors on new vehicles. There isn’t one for low oil, like say two quarts? 

Many of the newer vehicles don't have oil level sensors on the engines.  Manufacturers are only putting an oil pressure sensor on the engine, and when that puts a light on your dashboard, its too late.

Thanks for all the input, Since Im in canada, We use KM not MI, so 6000 Km = 3728 Miles.

 

Once again, 1 L usage for 3728 Miles, Normal?

 

 

That would be well within GM's accepted limit range of 1 quart in 2000mi/3218km.   

 

There are also many factors that can change that too.  Towing, brand of oil used (some could use more, others less), fuel, idling, heavy right foot, etc.

How many total kms on your 2021 L3B?

When did you last change your air filter? 
Ever change your plugs? 
What engine oil brand( chemistry to me) do you run?

Unfortunately with these 2.7L it seems to be a common issue. My 2.7 has around 116,****** miles on it. And I consistently burn between 1 and 1.75 quarts per oil change. I try to change the oil every 5000 miles or around 30% on the OLM. I keep an extra quart in my truck and top it off every few thousand miles as needed.

I had a couple of cars in the 70's that used a qt of oil every 500 miles. A qt or 2 between oil changes doesnt concern me. Of course I check my oil regularly also. Why some people think they dont have to is beyond me but so is a $7 cup of coffee.  Considering how the modern internal combustion engine operates I am surprised its not considerably more.

My first job before working in the family business was pumping gas in NJ. You couldn’t pump your own. The routine was checking air in the tires, windshield cleaning and checking oil. All before your tank got full. The oil was right at the pump. And people mostly paid in cash. You could tell which cars were turned by the tail pipes. Gas was leaded. Oil using was normal engines ran dirty. Unless you were a gear head most vehicles ran out of tune. Usually were done or closed to it at 100K miles. In contrast my brother in law was at my house this weekend with his 08 Yukon with almost 300K miles. Nothing but maintenance.

I’m old and repeat sometimes. Not as bad as my mother, yet. Repeat you want? Follow the oil threads.

My dealer service mgr says the PCV system is too “ strong “ for the design. I’ll take a qt in 5000 miles and run the RLI 5w30

thats $3.50 a qt and getting good wear and combustion readings. 
I purchased a 1978 J20 Jeep and it’s using no oil. 360 V8 I think.

Yes, Ive been running the RLI 5W30. I'm at around 4200 miles on current oil change, and I've only added about 1/3 quart of oil this interval. And it still looks nice and amber when I check it on the dipstick. Pretty good stuff!

    • Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift. (Corvette Only) After changing the exhaust sound they get a popup that "mode change not applied", even though it was. -When changing volume, the volume bar is for Traffic instead of Audio. -(Corvette Only) Improvements to the placement of buttons and text. -If the customer receives the message "Apple CarPlay Could not connect", the cursor might move in the opposite direction than expected when using the control knob. -Android Auto automatically starts playing their music, even though they have turned that off in settings. -Intermittently they have a red OnStar LED with no OnStar function and/or no audio. -The minimum length of the Wi-Fi password was increased to 12 characters. -The popup message "Driver Attention Check, check your mirrors or Super Cruise will shut down" may not have come up on the display when it should have. -Startup animation added for 20th anniversary of the V-Series on Cadillacs. -The Navigation app received location improvements when going under long underpasses. -In the Navigation app there are filters for charging points that the vehicle cannot use.   V164 Most Notable Improvements Most notable improvements contained in this release may include: Apps Intermittently, an “SD Card Removed” message will pop up in the Navigation app. While in the audio app, the radio may stop working. Trailer Tire Pressure sensors may not be learned in the Trailer app. Not being able to return to the home screen while in the Camera app. After an ignition cycle, the radio might go to a black screen or stop working if using Sirius XM.

After receiving and ending a call on the secondary paired phone, the cluster may get stuck on the phone menu. Bluetooth Intermittent Bluetooth connection loss.
    • Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated. 
    • We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person. 
    • We had a pretty big cars and coffee in Indy this past weekend.  Pretty much anything and everything was there.  
    • Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
