Oil Catch Can inquiry

[cncBilly]

I have a 2012 Charger with 110,000 miles cause I do change the oil religiously, full synthetic oil every 8,000 miles. The Kia dealership I bought it from said I need to change the synthetic blend oil every 5,000 miles so can I change the catch can then?

You don't change the can you just check it and empty if necessary. I've had my ADD W1 single can set up in for about 5000k I have checked it once and took out about 1 and a half tablespoons of oil. Pure oil no guck of any sort.

Right that’s what I meant by changing (checking). I’ve read too many articles on checking the can from 500 miles to 1,000 to even higher miles so I thought every time I get a oil change (5,000) I will check it.

Yeah...... Catch cans are expensive and complicated. The cheaper approaches require the owner to monitor and drain the can, which simply isn't going to happen on a typical production car. Or they would have to fully integrate it into the engine like Volvo does, but that requires quite a bit of specific packaging and design to make it work. Which is expensive. OEMs are extremely money driven. Don't be fooled otherwise. If an accountant determines that the potential increase in warranty work costs less than the delta production cost, then they're going with the cheaper design. Why do you think the front end of the stinger has struts?!

And the OEMs aren't convinced that intake valve deposits on a GDI engine are a problem. Doesn't mean they're right. This is the kind of thing that will take years to really show. Sure, they do lots of testing, but it's focused on economy and warranty claims. Just like transmissions with "lifetime" fluid. Doesn't mean the fluid lasts forever - just means it's likely to last long enough for the warranty to run out. Hell, my Volvo doesn't even have an oil dipstick! Does that mean oil never needs to be checked and maintained?

Why does it have the front strut bar?

Why does it have the front strut bar?

Which car are you referring to that has a front strut bar?

I've been running an OCC for about 8k miles and here is a pic of its effectiveness so far. Not much but it's something.

I have had Mishimoto catch can since 2021, no issues and the can was getting half full every ~4K. However, I noticed a new buzzing noise from engine bay under acceleration a week ago. I checked almost everything except the can but wasn’t able to figure what it was. I removed my catch can and the buzzing went away!. I’m sure my PVC valve was making the noise - it must’ve not be happy with the can for some reason. I assume the can seals failed or something so be aware of this.

ADD W1 here. Just had my 3k oil change and between 600 and 3k miles it caught about 2floz of gunk.

My understanding of my makers don't include them from the factory is this: yes, the concept of GDI engines getting gunk on the intake vales is known, but they have to manufacturer cars to the lowest common denominator. While there are some self-emptying OCCs out there, if it's like mine then at some point it might fill up via neglect, and if I am not mistaken not emptying it can cause some real damage. Now, it sounds like they might not have the brightest tech at the dealership working on the oil changes, and emptying the catch can is one more thing they can screw up (or the owner can forget to empty) That puts the onus on Kia to repair the damage for not emptying the catch can, or the masses complaining the 'they were never told they had to enpty it', or 'other cars don't have that problem '.

OR

They leave the catch can off, and every tune-up they can charge the owner to clean the intake manifold. One might cost Kia money, the other can make them money.

In my case, sonce I don't deal with stealerships unless absolutely necessary, keeping that gunk out means less to clean up later. If I assume that all if the gunk caught in the can would have coated and possibly burned itself onto my valves, then emptying the can is easier than cleaning the valves.

My $0.02; no refunds.

I love my ADD W1 Twin Can Kit, it is pretty easy to clear and it gives me peace of mind while I add more parts to the car. I think the biggest issue with adding these from the factory is that the average consumer is not going to want to do the extra maintenance.
