I'm picking up my 2021 CX-30 Turbo Premium tomorrow. I've never owned a Turbo but all of a sudden two people I know told me to get a catch can installed when I get the car because it's a Turbo. Mazda has control of this, from what I can find. Any thoughts on the catch can issue or is this another gimmick that doesn't really help anything? Thank you

A “catch can” is an aftermarket device installed in the PCV line, it’s essentially a small collection vessel to keep blow-by oil out of the intake and must be emptied regularly. Some swear by them, some swear at them. The fact it’s a turbo engine shouldn‘t matter, and to me it’s a wonderful device designed to separate you from some of your cash. YMMV.

Prevent pvc from clogging and prevent carbon build up. Also help with crack pressure issues.

Had it on my 2013 speed 3 and at 210k km plus. Didn't have pvc issues or dirty valves. Mine was pretty clean before I sold it. Still does 22 psi boost on the stock ko4.

Driving distance, climate and elevation plays a big role.
Summer I have to drain it ever end of month. Winter I had to drain it every week with a heater pad mod. Damn -40 Canadian winter

Either there is a perm plate design out there. Installing the OCC is a good preventative maintenance for the turbo engine.

At the least I would consider a turbo timer. A post lube kit wouldn't be a bad idea.
I forgot about turbo timers. If I recall correctly, they're supposed to keep your hot turbo spinning after you shut down so it cools down slowly. The very early Saab & Volvo turbos back in the day ran very hot. Not sure if a timer is as essential these days.

Turbo timer is good to circulate the hot oil from the turbo.

Usually what I do is drive gingerly for 10 min before heading home. Then let it run for 30 second and then turn off.

Don't run cheap oil also.

speaking of cheep oil.... I dont have much confidence in the Oil Our Canadian Ontario dealers use from petro canada... I think castrol or penzoil platnum plus is allot better.. I will be useing that in my new 100th aniversery mazda 3 sport and not the Cheep petro crap the dealer gets in bulk... whats your option on the petro canada oil if you know anything about it.
