Oil Catch Can for Direct Injection Engine

[True Blue]

As many know the down side of direct injection is severe carbon fouling of the intake ports and valves, leading to possible issues down the road. I've been reading that adding an oil catch can help alleviate this carbon issue. Would installing a catch can be a good idea? Vehicle in question is a 2016 Santa Fe, with plans to keep it as long as possible. Rick, I would love to hear your thoughts on this, as we own identical vehicles.

Thanks!

Yes bought a '16 Sante for Kath this past spring. As per the norm, difference we are seeing after dumping the factory suggested oil grade / oil change interval is a bunch. In other vehicles we've been testing / monitoring, change in intervals and oil grade has reduced oil accumulation in catch cans from substantial to trace only (2.7 EB / Coyote / Ram Hemi etc). If you install a catch can, would be interested in your results both with factory suggested grade and interval then dropping to 5k on full syn 10w30.
If you go catch can route, be sure to find one that does not use loose steel wool. Far too many learn the hard way when a piece of wire breaks off and gets sucked through the intake.
As for the SantaFe itself, never seen Kath so happy with a vehicle. Know she's going to enjoy heated seats n steering wheel over the winter, pano / sun roof gets lots of use as well. Opted for remote start unit from 12v Solutions in the US as it retains the factory key fob (installing soon, it's a 100% plug and play with no programming required). Only downside, they are so popular made a mostly loaded / low miler (ok add priced right cause I'm thrifty) really hard to find but was worth the effort.

I got a knockoff of the Mishimoto catch can from Amazon. Like 1/4 the price of the Mishimoto. Installed on the Accord. Using same grade oil 0W20 and same 8k interval, the can was half full. Last year I did Seafoam in the gas tank, engine and throttle cleaner when installed the catch can. I find the car runs better and has more pull now. I can get the tires to squeal upon take off more often now. Never did that before I did the Seafoam and catch can.

Thank you for your in-depth reply and tip about the catch can.
From the get go I've been running full syn 5w30, oil changes are at 3-5K/yearly. I never thought about running 10w30, on the next oil change I will make the switch.
I'm happy to hear Kath is enjoying her Santa Fe, ours has been a fantastic family hauler. Only thing that doesn't sit well with me is the spontaneous engine failure where mileage is not a factor, I hope that day never comes.

Thanks for the reply. Do you have a link to the catch can? I wouldn't mind checking it out.

It doesn’t come with hoses which was fine. I ended up buying Mishimoto hoses from Amazon as I didn’t want some random cheap hoses.

Combo of 0w20, direct injection and insanely long oil change intervals turns engine oil in to 2 stroke gas.
See it lots.

I'd think for colder weather, especially if it's around town use only, 5w would serve you well.
It's sad how many mfg's are seeing premature engine failure or just plain worn out and chugging crazy amounts of oil. I still think it's more oil n interval related vs what peeps think as we have number of customers sporting high mileage rides with original engines in vehicles said to be super failure prone. While good maint and correct oil can't save a bad design, no doubt it makes at least decent engines far outlive the vehicle they came in, yes no matter the mileage.

Thanks again Rick!

Curious, are you finding a lot of what is happening from German vehicles?

Dealership quipped that my car has been modified after seeing the catch can ?? ( it was just in for an oil change)

Interesting. We bought a used 2018 Mazda CX-5 GT w/2.5 GDI engine in May this year with only 19K kms. on it (now has over 30K kms) This video makes me a wee bit nervous given the comments in this thread, and now seeing how dirty this intake is with only 28K kms. on it. And not exactly an easy job to remove the intake to clean it up.

Appears Mazda has an oil catch can already built in, though the YouTuber here doesn't indicate it's something you can empty?

Go to the 8 min. mark on the video to see the condition of the intake and mention of the factory catch can....

And yet Ford sells catch cans for the V8s…

If you’re getting a catch can that needs 3/8” hoses, let me know. I have a leftover length from when I did mine. You can cut the length you need and give me back the rest. I also have different size worm clamps that should work too.
