Oil catch can comparison - test results
 

I see the other thread got shut down, so hopefully this one can be dedicated only to actual testing results as myself and Monte start to get some...

First, I am in no way affiliated with either JLT or RX at this point in time. I'm running some independent testing to support the good of the Mustang and track cars.

My setup: JLT and RX in series on the passenger side. The JLT is currently in line first, then the RX, then back to the intake.

Test conditions part 1:
Location: Thompson Speedway Motorsports Park 1.7 mile road course
Date: July 22, 2014
Distance driven on track: 130 miles
Time driving on track: 2.5 hours
Fuel consumed: ~24 gallons

Results (measurements pending my acquisition of a measuring device....)
JLT allowed significant oil to pass through, which was caught in the RX can. The RX can caught approximately double what was captured in the JLT can even being downstream and catching "cleaned" air.

Both catch cans have been emptied and reset for my next outing which will be a 2 day event at Watkins Glen in NY coming up in mid August.

Hmmmmmm......

I am not making any conclusions yet of course, just presenting some data. As an engineer, I rely on multiple data points, so more will be coming for sure. But I'm encouraged by these initial results and surprised at how much oil was going right past the JLT separator...

As a side note, the quantity of oil collected in the JLT separator is extremely close to the quantity I have collected from it for my previous 4 track outings this season for which I had it installed. Unfortunately I don't have those data points to add in, but I so nothing out of the ordinary in terms of the oil collected in the JLT piece for this event. Only was surprised by how much additional oil was caught in the RX can!

So far, I don't see anything of merit. We all know the the JLT captures next to nothing. And we've also seen this same inline test done with JLT and Bobs, and Bobs caught more than double the JLT.

So the RX may be roughly the same as Bob's. I have had no experience with any other catch can besides JLT, so I was happy to have pulled a lot more oil with the RX can.

I'm collecting and providing data as I get it

Thanks for doing this testing and posting your results. :nice:

I can send you a used large body Moroso for a comparison, PM if interested:

Sending PM

I'm about 500 miles into my test. I will probably post the first round of results at 1,000 miles. I will be interested to see how the Bob's does since it appears it's a forum favorite.


dmichaels,
Did you happen to check the line coming off of the RX can and going to the intake for signs of oil?


Wayne

Not yet - I will do so this evening.

Ok, thanks. This is what I like to look for to see how a can is working.


Back last year when I first got my UPR can, it would catch a lot of oil but the line at the intake would be soaked with oil so it obviously was also letting a lot of oil through.


Wayne

Interesting!

Here's some other info for you guys. I emptied my bobs for the first time after ~500 normal miles, mostly city. No measurement, but approximately 2 tablespoons.

Will want to see the results of the Bob's. In testing in the past, the RX still caught app twice as much as the Bob's unit, but independent testing here should confirm that.

And anything technical, just ask and I can provide all the data anyone would want.

There have been close to 40 different cans tested this way (the fairest we can think of) and the best only caught 45% of the oil and the RX caught 95-99%. But time will show.

I 'was' going to ask for a Bob's catch can for next Christmas, to replace my JLT. Going to see how this test goes first :)

$300 for a catch can though?


(referring to the RX piece)

About the same price as a Peterson or Mighty Mouse.

Huh?

WTF are those?

^ LOL... exactly my question.

Stang TV did a review on the Peterson:

So bobs catches double+ over the jlt. RX catches double the jlt. But the RX also catches double bobs?? Come one man. Quit with the bs....

And PLEASE. Explain how you know what % you're capturing. You have no idea that the RX is getting 10% or 80% of total. I've asked this now 4 times. Your refusal to address proves your lack of credibility.

Stick with bobs bro. Too much bs with the RX can. Plus it's more the double the cost.

Never heard of um. I bet tuner boost has tested them though! And I bet they capture less than half of the RX can too!
