Do I really need a catch can???

[FrankM]

I have a 2020 ecoboost premium that I purchased in 11/22, it had 43k on the clock. Had the car for two weeks, the engine self-destructed and Ford replaced it with a new long block. Since then, I've put 20k on the new engine and I wonder if I need a catch can. The car is 100% stock. If I need one, which one is best?

If one were really needed on a stock, street-driven car I’m pretty sure Ford would have popped the $4.00/car to decrease problems and increase customer satisfaction.

You need to spend 2-3 hours researching oil separators.

Having a catch can is something good to have, can not having one destroy your engine no. It is good preventative maintenance. I'm sure there is a lot of detailed information out there on why it it is good to have one on your vehicle.

A catch can is more for cars that live at higher rpms. If you drive it like you stole it all the time then its not a bad idea. But for a normal daily it's not as important. However, I agree with above statement, it's good preventative maintenance. It helps clean the air going into the intake by pulling the oil out of the vacuum lines.

I’m not exactly sure how the smaller Ecoboost is plumbed, but it’s not a bad idea, particularly on a boosted application. I ran a dual setup on my F150 and caught quite a bit out of both sides. But, it was tuned with downpipes making 375/500 to the wheels and I rode it pretty hard.

The money isn't the issue. They won't put them on every car because they know most people will not want to remember to drain them every now and then. Maybe as an option, sure.

I think on an FI it should be added. It doesn't hurt. I have a UPR catch can and breathers. Car isnt a daily driver though. Will check the can soon to see the oil collection. When I added the blower guard I noticed oil around the inlet tube when removed. It wasnt much though. UPR is a very clean set up

The main reason for a catch can is to prevent fuel dilution from the oil vapor/mist that will result from the mixing of the oil with fuel in the combustion chamber, it will reduce the octane rating of the fuel/air mixture which can lead to detonation under correct conditions which is never good. As stated, it is more of an issue in vehicles that are driven aggressively or used frequently for track days.

It will not hurt the car in any way for a daily driver but will certainly benefit if car is driven hard in upper rpm range at any time. It's the old adage of pay me now or pay me more later.

I have one on my ecoboost since it does see 24 psi boost at WOT fairly regularly.

No, you don't really need an oil catch can on a stock vehicle.
If it was so great to begin with the manufacturer would have included it from the start.
If you decide to turn the car into a modded mess then I guess it might make a difference.
My advice: Unless you know what you are doing, don't turn the car into a modded mess headache and skip the catch can.

The car is 100% stock with a new engine, looking to keep it for a long time

Can't hurt, but really not critical for a stock motor and 90% of normal or even aggressive driving

I'd encourage you to install one. I use a UPR, passenger side only. I don't drive my car hard. I've found that if you change your oil every 5k miles and empty the can then, that's probably often enough. I find about 25 mL (about one fluid ounce) of oil in it per 2,000 miles or so. I'd rather not have that going into my intake - it can't be a bad thing to catch and discard it - and it gives me a happy excuse to get under the hood once in a while. Easy peace of mind if you're down for checking it and emptying it every so often.

Not sure a out ecoboost engines but if they're the same as the coyote, it's nice to have one on the passenger side. A catch can was one of my first mods and I empty it every oil change. If you do get one make sure you mount it so it's easy to take off or access.. they do help keep everything clean inside where there should only be air...

I put a Ford Performance catch can on my 2017 GT. I put it on the left side (passenger) with a steel tag that says clean at oil change. There never is a lot of blow by oil but what I do get out of it never reaches my valves. Good thing in my opinion.
