Nice video but I'm a bit skeptical of any endorsement without thousands of miles of real world testing. Time will tell but perhaps the oil makers are attempting to address it sufficiently.

My UOA is why I moved from M1 (FS) 0W-40 to Castrol Edge 0W-40 for my T-GDI equipped Optima (far less oxidation, less viscosity shear down, etc.). I also run a PCV OCC and an OCI of 4K miles as a result while running Top Tier fuel. Doing the above I'm hopeful to slow down significantly the carbon buildup on the intake valves but I know at some point a good mechanical (walnut blasting) cleaning will have to happen (hopefully at 100K miles on my engine).

I want my oil to say "Nope"..and "Nope"!😂

Ok, all joking aside.. basic but informative, like you said.👍

fact is! as the years go by + miles pile up the carboning issues with DI will show up costing $$$$ for a proper mechanical cleaning!!! its not if but WHEN as engines vary like everything else some better others not so much like the girlfriends traded 60 thou 2.5 2013 malibu using a qt or so on a thou!!

I thought Ford would void your warranty? Is that not true?

That's a great question for a current Ford owner. One question I'd have is how's that different than installing/using any non OE part? In my estimation a catch can doesn't substantively alter the PCV system not like say dropping a supercharger in would. I know with Hyundai/Kia they won't warranty any owner installed part nor cover any damage any owner supplied part causes but otherwise you're free to do with what you wish..it is after all your car, not theirs.. it's just doing so (installing aftermarket parts) comes with certain caveats.

No simply do to fact GDI has been in mainstream use for nearly a decade and half and the problems you have described affect very few vehicles.


make the inside of your engine oil cap white.
don't use.

I've said this for a decade+ it is the responsibility of the catch can supporter to prove it actually does something.

Somewhere in that video (1:28 time frame) he says that oil can leak down the valve guides and contact the intake valves especially as the oil viscosities continue to become thinner for efficiency purposes.

is he talking about x20 or x16 ....
continues to become thinner for efficiency purposes ...

Translation: Thin oil = not very good ... at least for di engines.

All the more reason to do what you can to prolong the life of the valve seals.. and be conscious of the time spent idling as that's gonna draw oil down. But sometimes there's just not much you can do about idling, in those instance it is what it is.

Well, they do "catch" some oil (vapor) exiting the crankcase whether or not it's enough to have a demostrable effect is probably debatable. (and fwiw I say yes..as any oil caught is less to coat the valves and that is a good thing IMO). I don't have one (I have PI) and I've never seen a "study" so dunno. I doubt it's the definitive solution to coking on the IV's but I don't think it hurts either. The way I see it, it boils down to ROI for each vehicle owner - can they justify the cost?.. it's a tool in the toolbox to address this unique problem, that warrants considering IMO.

The interwebs have a way of getting people to hide under their chairs. GDI has been around for some time now. Like other advancements there are some teething pains but the way things progress these days, waiting for the bugs to clear usually means newer advancements come on the scene while you wait.
