Question: CX-5 turbo oil level drops before service interval

MileageGuy58Community StarterMar 10, 20262021 Mazda CX-5 TurboSan Diego

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? I'm in San Diego. Appreciate any ideas on what to check first. What am I missing?

Intermittent stuff lies if you only catch it once. Two 2021 Mazda CX-5s can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. On “cx-5 turbo oil level drops before service,” that was the fork that mattered for me. Parts cannon is a personality type I try to avoid. Cold start is when I can actually reproduce it.
