My only gripe about the CX-5 (and most modern small turbos) is that it's a direct injection engine. Is anyone using an oil catch can on their rigs? If so, any recommendations on a specific can? Any pics of the placement?

I can not post mine because I have modified my Corksport and it would not be the same as what you get from them.

This and all catch cans will only reduce not eliminate the problem with the direct injected engine. However a water meth system will prevent and clean the intake system ,combustion chambers and even keep the exhaust system clean.

And it is not a problem solely because you have a TurboCharged engine. It effect and concern with any direct injected engine.

 

I have never even heard of this pan, but I'm guessing it would probably void Mazda's warranty? But I am concerned about the turbo's life span.

 

Yeah, I know the water meth system is the best way to go - I may consider it given that I'm planning to keep the car for a while. What about an AOS? Seems like it should do a better job keeping the system clean, although not as effectively was a water meth system. Is my thinking right?

 

We tested them waaaaaaaaaaaaaaaaaay back before they were so much on the www market. If I post to much info a few of those that offer it are going to know who I am... if they are still active looking around on vehicle forums. lol Then the debates and arguments will never ending. I am what you call a BS buster much like the old TV show MTHY Busters. I will get a aftermarket predominantly performance and small team of us would find out if they actually worked as claimed. These were not published anywhere that I am aware of. I did write a couple technical articles about aftermarket inter-coolers that got a few manufactures pissed but they left me alone because they could not prove what their product claims were. My testing of products was actually not to dis anyone's product but more for me to decide if I could or wanted to offer a better mouse trap. I NEVER Engineered or developed any sort of Catch Can System to offer in my line of Performance Parts. I have a pretty good reputation in the Performance parts world for having things that work as claimed. lol
Essentially aos is is an over priced catch can that only somewhat places vaporized oil back into the sump instead of you manually removing from the can. You can not fight the laws of physic, fluid dynamics and thermal dynamic applied principles to how motor oil fundamentally works.

I have had an experimental Catch can zip tied to my MAZDA's PCV system as well my own catch can configuration on the breather side now for almost 7000 miles without a drop of oil yet or even a oil film on the pre hoses to the catch cans? lol This means nothing so dont read into anything that I did not claim about my testing on my MAZDA as it is for my own curiosity about the Skiactiv engine PCV system being very good over other manufactures engines. So far I am am impressed.

I will suggest again that you get and invest in a water meth system instead of catch cans or aos and get the benefits of increased fuel economy and the cleaning effect is has on the engine.

 

Where would one start looking to find a good a water meth system for a Cx-5 turbo?

 

So, I just read through this thread, did some research, and came up with absolutely nothing in regards to water meth kits for the Mazda 2.5 turbo… so I made an account so I could reiterate the request.

 

The kits are UNIVERSAL, it requires a little DIY install. They are fairly simple and the installation instructions from the top vendors/suppliers of the water/meth kits are done very well with illustration. Common sense and carefully reading will make the install an easy project

 

Thanks Callisto. I wasn’t sure — I’ve been part of the Subaru community in the past, and on those engines a tune was necessary to reap the benefits of water/meth injection, otherwise, it’s just making a certain portion of the charge inert and actually reducing volumetric efficiency.

Is it the direct injection that makes the difference here? Is this engine better able to detect the increased knock resistance?

 

Technically to achieve maximum benefit you need to tune the engine for the use of W/M. Those ECU calibrations you speak of on the Subaru forums no doubt from those that are driving very spiritedly often and getting into the upper limits of the boost pressure. Lower engine speeds and less boost more common with driving has less effect on ECU with the Volume of air charged lost by water or water myth injection.
