Auto question: does anyone run an oil catch can on their Direct Injection engine?

Might consider doing this once the 10 year engine warranty expires on the wife's 2019 CX5 Turbo which has only 18k miles on it right now.

Googling yields a general "yes, it's a good idea" consensus but wondering what BARF experience is.

I'd add one to my Ecodiesel IF I didn't have to smog it since that gunk combined with EGR will just gum up the intake. Instead I run an oil that has a higher than normal NOACK Volatility Rating to minimize evaporation and also run the oil level on the lower side to possibly reduce crank case windage.

In your case....making sure an oil formulated for GDI engines is also a must.
 
If I had only 18k miles in a decade I wouldn’t worry about carbon buildup

Is a 10 year warranty standard for Mazda ?
I'm in a similar situation with just 4K miles per year on this truck now that my wife started riding bikes. I mostly only use it for longer trips/towing.

Might make the buildup even worse when the oil doesn't reach full operating temp if its only short trips?
 
I recently bought a GMC Canyon but was considering the Tacoma also because of its port injection in addition to direct. But I liked everything else about the GMC more so went with that instead

18k in 7 years, but that is not a ton of mileage obviously which is why I'm noodling doing something in 2019.

Mazda extended the warranty on many turbo engines.

We are careful about letting the idle drop down to "normal" at startup in the AM before taking off and not running the turbo hard and then turning off the engine so likely we won't experience any issues.

Why Was the Warranty Extended?
  • The Defect: On early 2.5T turbo engines (specifically those with serial numbers before June 9, 2020), the cylinder head can crack near the exhaust manifold. This allows engine coolant to leak out externally. [1, 2]
  • Customer Service Program (CSP11): Instead of a standard recall, Mazda initiated a Customer Service Program in the US to cover the costs of this specific repair. [1, 2]
  • The Cost Relief: If left unaddressed, the leak can cause the engine to overheat, mix coolant with engine oil, or result in a blown head gasket. A cylinder head replacement typically costs $2,500 to $4,000 out of pocket. [1]
 
I left the automotive profession just as direct injection was coming out.
I saw some growing pains first-hand.
That was about 10 years ago.
I was curious about any future scenarios as those vehicles aged.
 
Yes. A good dual stage catch can and an updated/upgraded PCV/breather can help.
I use the UPR catch can on my 2017 twin turbo 3.5 ecoboost.

Didn't need a walnut blast until 195,000 miles. The prior advice about the oil that is used is on point.
