I use synthetic oil. Is the next step to better lubricaion a filter and catch can added to the PCV circuit? Would it help that much, to have that little bit of crud removed instead of sending it back into the engine? Would this kind of setup help in cold weather or short trip driving?
The next step in lubrication

What synthetic do you use? Perhaps a better synthetic is the next step.
martyi: I was thinking more on the lines of if he is using a Group III then he could step up to a PAO base or from either of those to an ester base.
Ugly3: Of course the engine will outlast the rest of the car with conventional oil, but that is not what he asked. He wants better lubrication, apparently regardless of whether is will be of any practical benefit.

Actually, I know people experimenting w/ filters in the PCV system on their saabs.
The PCV catch can I am using is catching a whole crap load of water condensation from the oil system and not allowing it back into the intake.
I have to dump it every week in cold weather. Stuff looks like light chocolate milk in the vial.

There are any number of things and if I were to implement:
1. pre oilers
2. bypass oil filters
lastly and a huge structural change: dry sump.
Obviously the thing to ask is what one is trying to achieve by going to the next step in lubrication. #'s one and two's logic goes something like this.
At an aftermarket cost of app 400 dollars (oem costs would be substantially less of course), preoilers provide pressurized oil on/to the moving parts which will otherwise rub against each other normally UNLUBRICATED causing up to 80% of the wear over time. They also can provide "emergency" pressurized oil when fuel starvation conditions occur. So given 80% less wear due to cold start up one can extend the OCI. To further aid in extention and even better cleaniness a bypass oil filter will further filter smaller particles not filtered by the standard filter. So for example 20,000-40,000 mile ocis can be gotten of course with analyisis if one is at all in doubt. So if you keep the car as a normal driver would 8 years and do between 12-15k a yearor 96,000-120k at one level does this make economic sense? In other words over the course of the mileage and time you would change your oil 3 to 5 times vs a more normal 32-40 times.

I was just asking because we have put pcv filter/catch cans on emergency power generators. They get started, run hard for a while and shut down. This one change has allowed the maintenance crews to extend the oci. I know that this is not typical automotive use, but these devices have helped and might work on motor vehicles, too. I've seen the inside of these filter and they catch a lot of gunkie looking stuff.
Sure, it will help the engine as long as it isn't a restriction to PCV functioning. Will it help the UOA? Maybe not but who cares? UOAs have limited ability to tell what's going on. Lowering the amount of oil vapor going into the combustion chambers is a good thing for keeping the pistons/rings cleaner and upping the octane of the air/fuel/oil vapor mixture. Did you guys ever burn motor oil in a cup with a blow torch and see how much crap is left behind? Motor oil "burns dirty". Gasoline just leaves behind mostly carbon.
Not to mention that a good catch-can will definitely help your catalytic converter live longer -- especially if the can is catching oil that gets by the PCV valve.
Cleaner rings, less carbon in the exhaust stream....cans are a win all the way around. If you ask me, manufacturers should put them on cars coming out of the factory and include instructions on how to periodically drain them.
I have two of these on my car (one supporting the PCV valve, and another for the valve cover breather to keep the throttle body clean):

Yes, they're expensive, but judging by what they catch, they're doing an excellent job. Very well made, and built to last forever.
No interest, just a satisfied customer.

i have the accurate mach. works catch cans on all my 2 cars and truck
I'll second BlazerLT, in the winter here (ha, its been mid 70's this week) the normal collection of oily stuff in my catch can has been a milky mix with more water and I'm glad its not going back into my engine or mucking up my intake manifold.
Yes, they've (air/oil separator) worked well for many people. Make sure you remove the little white filter in them since that seems to negatively affect PCV vapor flow and function of the whole PCV system. Wal-Mart has them at a good price.
My question is this...since several auto makers have found that 5w20 will not grenade their engine, is anyone testing a 15 or 10 weight?
