Mishimoto Mazda Miata Baffled Oil Catch Can

Scenario
2018 Mazda MX-5
Installed catch can around 7,000 miles.
Checked the catch can at 10,000 miles, it was pretty empty.

Now about 20,0000 miles the “catch can” caught about 2 oz of oil. I think it was definitely half full.

I’ll keep track of this and will see what it looks like at 25,000 miles.

I’m more relieved that this oil didn’t go back into the intake.
