JLT Performance Clear Anodized Passenger Side 3.0 Oil Separator Kit for 2018, 2019 and 2020 GT Mustangs.

Your 2018-2020 GT Mustang has a PCV (Positive Crankcase Ventilation) system that directs the pressure from the crankcase vents back into the intake system. This, unfortunately, allows oil vapors to also pass through and collect in the intake tube, which can result in dilution of your gas and decrease the octane in your fuel, which can affect your Mustang's performance. JLT Performance's 3.0 Oil Separator Kit can prevent these adverse effects and ensure your Mustang's performance isn't affected.

This 3.0 oil separator is constructed from high-quality billet aluminum and has a clear anodized finish for a great under the hood look. It features a dual-stage filtering system, so fine oil vapors pass first through a fine mesh stainless steel screen that collects the vapors as they pass, then, once they are heavy enough, they drop to the second filter. The oil droplets pass through a 1/2" thick 1/16" aluminum honeycomb filter. This second filter is where the droplets grow larger and fall into the bottom of the canister. This process prevents the oil vapors from getting to your intake and eliminates them from your system entirely.

JLT designed a knurled tank base that twists off easily so disposing of the collected oil is hassle-free. An O-ring is included to keep a tight seal and avoid leaks. Oil blow-by accumulation varies based on temperatures and driving conditions, but the tank only holds 3oz. of excess oil, so it is paramount to dispose of the oil before it hits maximum capacity.

Oil Separator (3024P-C) Features:
- Billet Aluminum Construction
- Clear Anodized Finish
- Two-Stage Filter System
- Maximum Capacity is 3oz of Fluid
- Easy Plug-and-Play Installation
- For 2018-2020 GT Mustangs

*This oil separator is not designed for use with Mustangs that have installed a supercharger.

Tech Tip: Once installed, CJ Pony Parts recommends to check the contents of your new oil separator every 1,000 miles until a baseline is established to avoid tank base overflow.

Installation Videos

Video Transcript

Today, in the studio, we're going to install something I would recommend to any new Mustang owner, and that's an oil separator.

This is JLT's 3.0 oil separator fitting your 2018 Mustang GT. Now, the oil separator's job is to keep oil vapor from going back to the PCV system, which can go into the intake and, over time, damage your engine. This will hold three ounces of oil and features a multistage filtration system inside.

To drain the separator, simply grab the bottom and unscrew it, and then you can dump it out. And here, you can see the filtration system inside.

The oil separator is going to be one of the easiest installations you're ever going to do to your car. Now, we removed our engine cover so you can see what I'm doing, but you actually don't have to even do that. You can reach underneath it pretty easily. What you're going to do is remove this line, here. These little gray clips, just push, and it'll pop off.

The JLT separator features the factory-style fittings, making for easy installation. Lock that into place there. Same over here, and your installation is finished.

The JLT oil separator could not be easier to install. I mean, literally, this is a less-than-a-minute installation, to be honest with you. It'll be something to be thankful you have. What I suggest is every time you change your oil, check that as well and drain it out.

Like I said, this is a very good idea for your Mustang, very simple to install. You'll be back on the road in no time.

This product will fit the following Mustang years:

Rated 5 out of 5 by from Exactly as shown Just like the other reviews, I will agree the install on this Oil Separator was extremely easy to do. I did not have to take off the cover to install, and the total install time was about 30 seconds. I only have 300 miles on the GT today, I will come back and update after 1000 miles to let you know how much fluid was captured.

Rated 5 out of 5 by from Great fit and Look This installation is as easy as it gets. I installed the oil separator in about 30 seconds. The fit and look are great. The directions instruct you to remove the engine cover, but you can get your hands in there to remove the factory hose, and get it installed without removing the cover.

Rated 5 out of 5 by from Buy this NOW!!! Ok this is an updated review, I was planning on to submit an update after I had 1000 miles on the 2018 GT but I couldn't wait. I am simply amazed at how much oil this separator has captured in only 400 miles! See the pic for yourself. I highly recommend this simple yet effective device!

Rated 5 out of 5 by from So easy to install I was pleasantly surprised how easy to install this oil separator is. I just loosened the engine cover, as taking mine off with a strut brace looks like a job, and was able to install it in a few minutes.

I'm considering purchasing the passenger side oil separator. This was an addition to my already exceeded budget for upgrades right now. Is it necessary to purchase the driver side as well or will the passenger side truly be enough?

Asked by: JBuff
You could use one or the other i would suggest both.
