Oil Catch Can

[Shortcut]

Wow you are much more precise with your measurement.
I don't think water is an issue. I just noticed a single water droplet when I did my sophisticated Chinese takeout transparent lid test . Nothing to worry about. I did notice a much more substantial amount of water and other interesting "stuff" (code for I have no idea what it was) during the first 500 miles. Being a brand new engine it could have been sitting around for a while (condensation), it also could be engine assembly products getting flushed out the PCV.

But to me that is the real benefit of an oil catch can, you can actually see what's coming out the PCV and how much. The added benefit is that it's not passing through the engine especially at startup. I added .25 quarts (about 8oz) of oil at 1,000 miles. I have "caught" about 5oz in the catch can. So most of the "missing" oil is leaving out the PCV. I check the oil after every fill-up, 5 min after engine shutdown. The Oil level has been extremely stable. The Oil looks clean. My MPG has been steadily climbing. All that tells me the engine break-in is proceeding nicely with no leaks (knock on wood).

My precision comes compliments of a graduated cylinder that has the various volume measurements marked around it. I'm pushing 12K miles on my 392 and have not had to add a drop of oil. It has read right at the top of the full mark everytime I check it usually on a Saturday morning when it has been sitting over night. I have taken advantage of two of the Jeep Wave oil changes so far though. It's a shame Jeep lowered the oil changes offered in the program from four to three though.

Any have a catch can mounted yet??

American Brother Design will come out with this soon.

I like this design, it is in the same area (different spot) I have mine.

Yup, much cleaner and less crowded on hoses on top of the engine. If only I can get it before my order arrives. Unfortunately, it was supposed to deliver yesterday, but now it says TBD again on tracking site. Then I recieved an email from FCA stating that due to the packages and options I selected, it might take longer than usual lol.

Update:
Available now to order.

Just put my order in, I love this design. I've been looking on how to do something similar as I'm not a fan of the other setups and their mounting locations.

Super simple and keeps the engine bay super neat. The best looking setup from my perspective.

American Brother Design oil catch can - just ordered mine, too!

Emptied the JLT catch can.

Had an ounce of mostly oil after 2000 miles.

There was a small amount of emulsified oil at the bottom of the can.

Was about to order but the one shown has different looking bracket and can is 1/4 turn from the perfect version. So now I am wary on what I might get?

Emptied my Catch can for more the fifth time today at 18185 Miles and was very surprised and concerned about the amount of water in the oil that was captured in the can. Not sure how the water is getting into the catch can oil. Pulled an oil sample on Oct 18th with 15301 miles and there was an immeasurable amount of water in that sample. I’m going to pull another sample shortly to see if any water shows up in the sample.

Should you choose to download the .pdf oil sample report, be sure to review the technician's analysis of the findings.

Check out this thread below as it was updated with Photos Etc.

Condensation.

Does your 392 sit for long periods between driving? Oil will absorb moisture and perhaps you are collecting water (are you seeing emulsified oil?) that is being separated out as it passes through the oil separator. My TRX sits alot more than my wife's 392; there was also much more emulsified oil in my TRX separator when compared to the 392.

It’s completely normal. The PCV system draws in outside air to the crankcase and back into the intake manifold. All that air,water,oil,fuel vapor being “sucked” out of the crankcase settles in the catch can prior to making it back to the intake manifold.

This Jeep is currentky my daily until I can get my LJR back from LetzRoll. The attached photos were taken today. The last two on the right are a picture looking through the bottom of the glass measuring container and the far right photo is looking into the bottom of the catch can.

Great input! Thank you! However, my concern is that none of the previous four times I emptied the catch can and every time before that there was no condensation in the oil, it was all oil. I'm also in Arizona and the humidity here is very low and not much rain. Looking forward to the results of the out of cycle oil sample I will be pulling soon.

This is a great example of why even in our port injected engine, a catch-can can be beneficial. Thanks for sharing.

I decided to empty my catch-can to compare. This is after about 2,000 miles. I also live in a dry area (SoCal). The 392 gets driven within the city at least 3 times per week, and offroad once a month to every other month. No water or other fluids noted at the bottom of the filter. The 392 is a 2021 with almost 12,000 miles on the odometer.

When or if you have time I would like to know how the install went.

I’m at 450 miles so far my average mpg is 15.7 it has slowly increased. What are you getting. Thanks

When I first picked my vehicle up from the dealer in Michigan (650 feet above sea level) during the break in period I got 400 miles before my first refill approximately 20 MPG running on 93 octane and stock tires. On my trip back to Arizona I continued to get 20 MPG until I hit New Mexico where 93 octane was no longer available and the altitude began to increase my mileage dropped to 17 - 18 MPG between fillups and continued to drop with continued increase in altitude until it settled down to 15 MPG where I live in Arizona which is about 4500 feet above sea level. Putting 37" tires on without changing the gearing (still have 3.83s with a Tazer Mini to adjust for tire size) cost me another 3 MPG around town so I usually run 11 - 12 MPG now. On highway trips to Tucson or Phoenix I can get close to 15 MPG.
