Good Afternoon,

Should we all have oil separators, are they just for certain driving styles, or does the need depend on certain parts being installed like HP increasing mods? Thanks in advance for furthering my education!

There's no empirical data on how much they help if any at all. In theory, they should help with the longevity of the engine but this is not proven. They definitely do not hurt.

 

Mines catches oil so I assume it's working.

 

it was the first mod i did and i have to empty it every oil change and once when i have about 50% oil life left. im probably going to get another pcv valve to put in because i dont think i should be getting that much.

 

I would say, oil separator for 5.0 is a must have upgrade, I drained full container of crap fluid just after 1000 miles, I have had dealer put amsoil 5w20 signature series as suggested by service advisor at 20k, now it has 23500, checked oil level on the dip stick and it is just above middle, I had to put entire quart. engine has no leaks, only thing I can think of is Pcv line sucking oil and burning, now I am trying to get driver side also.

 

It's better to have one, but the car should be perfectly fine without one. I think racing conditions are where it may be more beneficial

 

My 2012 used from day one. I'm guessing it's because of the piston oil squirters which are cooling jets that target oil at the underside of the piston to lower temperatures and improve piston life.

The JLT oil separator will get about 1/2 fill in 3,500 miles which is only a few ounces, but the crankcase is about 1 quart low. IMO it's not a big deal with an 8 quart oil pan. At least I know the coyote is getting lubed.

I have one on my 2014 GT and it's one of the first things I did to the car after buying it. I originally installed a UPR catch can but am now running a Bob's catch can. I have caught quite a bit of oil in mine so it's made me a believer in these things.

Great feedback as usual, everyone. Thanks. I'm going to order one.

 

I think I need an education as well.

I know the point of a catch can is to "catch" oil going into the intake and causing a decrease in the octane ratio of the air-fuel mixture. This of course can rob power...

But isn't oil going into the intake DE-facto by design? As in to help lubricate the intake path of the engine, and perhaps the combustion chamber as well?? I'm thinking why would the engine be designed this way if there wasn't a reason for it in the first place...

I honestly don't know, I'm just thinking out loud here. Please enlighten me, I lack knowledge in this area.

 

The PCV valve is one of the first smog control devices added to engines to help prevent combustion "blow-by" from entering the atmosphere that we breath. It has nothing to do with the actual performance of the engine; and, in fact, contributes to a very minor decrease in performance due to dilution of the intake air. The catch can, if properly designed, helps trap oil that may be suspended in the blow-by being fed into the intake.

You don't want oil in the intake charge unless your running a 2-stroke engine. It does no good for a four stroke engine in the Mustang. Oil is being properly fed to the engine parts in other ways.

 

Your engine won't blow up without one. If you love your Mustang and plan on keeping it for a long time, i would get one. I have one and it collects around 1 oz every 1,000-1,200 miles.They only cost around $100 and you can install it in a couple seconds

I don't think it's from the oil squirters because I have a 2014 and Ford removed the oil squirters on the 13s and 14s - that's where the extra 10 hp is coming from. I don't have many miles on mine but there seems to be a fair amount of oil collecting already. I thought it might be because these engines run pretty hot compared to other cars I've had so I figured the oil was just vaporizing more but I was told most of the oil comes from the passenger side and it wouldn't make sense that one bank of cylinders is running hotter than the other. I definitely wouldn't want all that oil in my intake though.

Here is a picture of my Bob's setup:



Here is a picture of the UPR setup I had before the Bob's.



Here is a picture of the oil I captured in the UPR can after about 2,500 miles.



The reason I switched from the UPR can to the Bob's can was that I was still getting a little bit of oil in the output side of the hose, even where it went into the intake. I read that the design of the Bob's can helped to prevent that from happening due to the hose from the PCV valve is coming in at the bottom.


On the UPR can, it has a round metal disc with holes in it that sits below the wall that separates the intake side from the output side. The wall doesn't sit flush with the metal disc so it looks like some of the oil would sit on the metal disc and run over to the side of the disc that covers the output side and the vacuum would suck this oil into the SS mesh and out through the output hose.


I haven't run the Bob's can long enough to see if any oil is getting through on the output side or not since I have not driven the car hardly at all since the beginning of November when I installed the Bob's can. The Bob's can also sits up higher, making it easier to access the drain on the bottom of the can.


The UPR can is a nice piece and it does catch quite a bit of oil.

Here are some photos of the inside of the UPR can so you can see what I'm talking about above and for those who haven't seen the inside design of this can. The drain petcock was not included in the original cost of the can. I bought it later from UPR.

 

I went with the bob's and love it.

 

This is the JLT on my 2011 v6. This is the oil it collected in just 100 miles [IMG][/IMG]

 

This and I have Oil Separators on both sides and have yet to get a drop out of the drivers side, just a fyi. Sadly, only 2300 miles on it that I can vouch for.

 

Say what?
