CX-5 turbo oil level drops before service interval

EuroBuyer81Community StarterSep 24, 20252021 Mazda CX-5 TurboPhoenix

2021 Mazda CX-5 Turbo, about 78,000 miles. I'm seeing the oil level fall enough between services that I now check it regularly. No obvious leak. For other turbo owners, what documentation/tests did you collect before bringing an oil-consumption concern to the dealer? Appreciate any ideas on what to check first.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2021 Mazda CX-5 is losing coolant with no puddle. Save the big job until that test fails. Write the result down so the next test isn't a repeat of the last one. I'd sleep better after that step, even if it finds nothing. If this is nothing, great. I want that in data.

OP update: scanned the 2021 Mazda CX-5 again and still only have the one pending code, no new lights. Only after sitting overnight so far.
