I wrote a post "Consumes 0.3L per 1000km"
GM KOREA really likes macro responses
It just says "please visit the service center."

Feeling frustrated, I made an inquiry to GM CANADA.
I barely got a response from the live chat consultation.
To summarize very simply, Only under the conditions set by the company, Consumption up to 1 quart (0.946 liters) for 2000 miles (3200 km) is normal

I think it's a fairly generous range
What do you think?

1 quart every 2000 miles would not be acceptable for me! GM recommends oil changes at 7500 mile intervals, so is it acceptable to be 3.75 quarts low between oil changes? The 1.3T only holds 4.8 quarts. On my first oil change at 3600 I removed at least 4.5 quarts along with draining the filter.

I am confused now

And I looked at the trailblazer vehicle instruction manual that I got from Korea

The manual says, "When engine oil is replaced, if the engine oil life system cannot be initialized, replace engine oil when reaching 5000 km."
Other than this, I can't find a phrase to change engine oil in a few kilometers.

Is it possible that the GM rep is referring to a rate at which the oil life declines (a sort of "consumption" of useful life), but not actually a rate at which the engine oil level declines?

i don't know.
It seems he just recited the information he had.
Seems to be the maximum rate allowed

Sounds like a cookie cutter response to me. GM is well known for those if you ever had to deal the the 8 Speed Automatic Transmission issues all they do is cookie cutter legal responses and slap band aids on the issue. They did recently about a year ago begin flashing TCMs quietly to adjust the real issue of the slip% tables causing the shudder issues but you'll never see them admit it. Truth be told your driving a DI turbocharged engine I understand your concern 100% I came from a 2017 2.0T Camaro these things have a horrible habit of oil ingestion through the manifold and vacuum lines. As temperatures change this gets accelerated if your seeing it in the summer 75+ degree months you have an issue if your seeing it in 60 or below it's actually fairly normal for this engine type. Just keep an eye on it every few fill-ups not trying to sound rude but it's not difficult to open the hood while your getting gas pull the dipstick and check your oil level. If it's bad document it. Keep a quart in the back trunk if it looks really bad and have your service writer or dealership you bought it at keep notes and ask for a print out. Better yet ask to speak with the technician who worked on your car or changed the oil. Most will be happy to answer questions that could make their life easier later on and potentially make a reliable request customer because happy repeat customers are still a dealership metric I believe.
