Excessive Oil Consumption?

Hi folks. I'm driving to Chicago from Seattle and back. So far I have driven 3000 miles (out of 5500 total for the entire trip) and have had to add 2 liters of oil to keep my oil level gage at MAX. This seems excessive to me, and I'm a bit worried about my engine. The engine has 59K miles on it, and on this trip my performance and mileage have been excellent. No blue smoke or anything like that.

2022 GLS 450 X167.

Any comments or advice?

I have many miles on our GLS, and we are close to the 60K mark now, with dozens of 4+ hours trips, as well as other longer trips from/to east/west coasts. Never had to add a single drop of oil, even when I drove 10K miles until my next oil change service with several long or state to state highway trips.
