Oil Catch Can - Surprised By Results

[BlaineBug]

I installed this oil catch can only 3,474 miles ago. It was installed 1,213 miles after the last oil change. I had not checked it until today when I did an oil change, and I was surprised to find that it was full, up to the treads! I can't imagine it was very effective if it was sucking in its own excrement. There was only a very small amount of "milkshake" at the very bottom of the catch can that was visible once I drained the contents. I use Kirkland Signature (Warren Distribution) 0w20, and this is a 2019 model year 5.3 AFM engine with nearly 69,000 miles. Thoughts?

You need to mount it lower. Gravity is your friend.

 

[Marky Dissod]

Catch cans should have sight glasses.

That would help probably yes, although the bracket provided is limited in regards to where to mount, and the hoses provided are short. Relocation would require some fabrication at the very least.

I'll have to check in 1,000 mile intervals and see what I find now. Of course this catch can is relatively small, and was the massive sum of $25.68 including tax. Although it did come with quick disconnect fittings so I did not have to supply anything as of yet.

I get milkyness in mine as well but not consistently. I've changed my oil multiple times since first finding it and the oil shows no sign of moisture or the same milkyness. So I have to assume moisture is making its way into the catch can through the fittings?

It's condensation. IMO it's weather and humidity dependent. But in the end the catch can is doing it's job on multiple levels.

@89Suburban
I do know gravity is my friend, but I am not a physics major, can you tell us why the catch can should be mounted lower?
I have the same set up and I empty mine at 2,000 mile intervals, it is two thirds full.
As for the moisture milkshake, I get that in the winter only, low humidity in the desert.
And yes, the catch can is doing it's job.

I just checked my catch can way early this time, only 428 miles post-oil change, and was surprised to find a bit of what appeared to be fresh engine oil (looked just about the same as the oil that went in, no water.) I did not measure it out, perhaps next time when I'm expecting it. For the last oil change I used 7 quarts 0W20 Kirkland Signature (Warren Distribution) and 1 quart Marvel Mystery Oil.

1 quart Marvel Mystery Oil.

I'm right there with you. I have a Range AFM in my Denali and also change out the oil at 5K miles with a bottle of Rislone. I have an extended warranty on the truck too, but I'm a firm believer in over maintaining my rides.

The quote I was referencing was for the Vice Grip Garage fans. That feller cracks me up.

I do not have any Range AFM, however if you ever have a warranty claim, make sure no one knows about that aftermarket device (I inspect warranty claims daily!)

 

[Darkstar72]

Whenever I do have leave it for service the device gets unplugged and comes home with me.

Just drained again, can't say how full the can was due to the stainless scrubber but it was at least somewhat full of oil. No oily/watery mix. Just oil. However when I check my oil level in the pan, it is still full!

This is what I found in the catch can after about 1,500 miles. 1,200-1,300 of which was pulling a fully loaded U-Haul trailer on a recent cross-country move.

That is inline with what mine catches, 2019 Suburban 5.3. I run a large can mounted off the radiator core support. I will get the milkshake in the winter months here in Illinois.

I was going to say that I thought it is excessive for oil consumption, considering that none of it is condensation/water/milkshake. This 0w20 oil is as thin as water. I'm thinking next time I'm going to use 5w30 from here on out.

Is there a preferred catch can manufacturer on these forums?

What brand/model catch can at that price?
