Catch cans are a gimmick! They condense combustion by-product, and oil vapors into liquid form. In normal PCV operation combustion by-product, and oil vapors stay in vapor form when they enter the intake, and are in extremely low concentrations when compared to the volume of air entering the intake.

Throw the catch can into your trash can, and you won't have any more problems!!!


I posted this in a recent thread:


A catch can is a gimmick, absolutely NO ADVANTAGES!! Check this out from a GM forum, if a GM product doesn't need a catch can, a Ford product definately doesn't need one:


good post from mike at Criswell, a forum dealer - after reading this, I took mine off and sold it.
Written to mike at Criswell when he asked one of his GM/Corvette engineering buddies about this…

MIke: "I was the one that contacted someone from the Stingray Consultant team from GM...Here comes is what he wrote back on this matter."

"The Stingray was evaluated with over one million development miles on 200 captured test fleet cars. There are tens of thousands of direct injection vehicles on the road from General Motors alone. During the evaluation hundreds of engines were literally torn down in to part piles and evaluated. There are hundreds of thousands of LSx family of motors (where part of this catch can hype started) on the roads and the many of these motors are running well past 250,000 miles without a catch can.

The cars have a 100,000 mile powertrain warranty and that includes mechanical failure of the engine. Trust me when I tell you that there are not reams of data (not even pages of data) on cars coming up lame because of oil at the MAF. It just isn't the problem that the "internet" makes it out to be. When you ask a GM Powertrain engineer about a catch can the reply is that the only thing you get is added weight.

In looking at the extra effort and added cost that went in to the Stingray, do you really believe for one second that if a $20.00 part attached to the engine would improve reliability, limit warranty claims and replacement costs, that GM wouldn't have put it on if it was necessary as part of their evaluation?

Every single GM engineer that I have spoken with told me in one form or another that a catch can is predominately a "gimmick" device created by tuners looking to make a few extra bucks on their engine modifications.

 

^This^

 

90000 miles on two Ecoboosts with no catch can and never had one issue. Remove it.... not needed.

 

Lots of great points here, I have nothing to add!

...waiting for those with catch cans to come to their defence as being "cheap insurance" (for a made up problem).

and the 10/30 has a 5.3 NOACK (I ran the 10/30 in my Explorer Sport

ecoboost)

Edit here is the Signature series oil specs http://www.amsoil.com/lit/databulletins/g2880.pdf

 

None of these oils are API certified, which is a requirement to keep the manufacturer's warranty valid!!

 

Correct they Exceed those standards by Far.
But If you need the starburst on your bottle, we do have those offerings too.

Here are the XL specs http://www.amsoil.com/lit/databulletins/g1404.pdf

 

but you get the privilege of paying $70+ for 6 quarts of that magic stuff. Whereas the OEM oil runs you $25.

 

If you want OEM oil that's great.
If you are looking for other options we have 3 lines of engine oils for Gasoline engines. (With good NOACK numbers)
And as far as the "Magical" stuff goes. You must be looking at the Catalog pricing on the corporate website. Forum members get much better pricing.
I did the oil in my 2016 5.0 for less than $70.

 

Motorcraft syn blend has a NOACK of 14%. Pennzoil Platinum for not much more money at the local Wallymart has a NOACK of 8%.
