You could pour it back in. Your oil is all ready contaminated with the same stuff. I'd rather pour in some fresh oil though. I usually don't get enough to worry about adding oil, but I change my oil ever 3,000 miles, which is about 6 months for me.

 

So you would put water in your oil? A lot of woolen in colder climates that DD the car were finding more water in the catch can than oil

 

Wow, thanks! I didn't know that Big Brother was watching. LOL

 

I just have an intake and tune, should I still look into one of these?

 

yes, any car with a PCV line can benefit from a catch can.
keeps your engine cleaner.
an ounce of prevention is worth a pound of cure.
if anything, it won't hurt.

 

The water bottle that I showed was and take car that is not running a tune (AEM). And that was only 5k

 

There's lots of water in your oil at startup. It's called condensation and evaporates. Pop your hood in the morning and look at your motor, now run your finger over the metal valve covers. That same water you feel is inside the engine.

I've never had water in my catch can, but I live in Florida.

 

Normally the oil in the air that comes through the PCV valve coats the inside of the intake, cruds everything up a bit & ends up being burned in the cylinders. It will eventually crud up the plugs, but since it is made from crude oil it does burn for the most part.

I wonder what synthetic oil does? Does anyone know? Does it even burn?
I am not saying that you shouldn't use synthetics (I do), I am just saying that using synthetics might be another good reason to use a quality catch can.

 

I was told the oil vapor into the intake also effectively lowers the octane rating of your fuel.....??

 

My catch can is from Stephs. It has a bit of foam like matierial inside. For awhile, I could open the drain and some nasty smelling water with an oily feel would come out of it. Did this several times. Eventually nothing came out...for awhile. So I opened it up, and a bunch of baby poop came out... YUCK!!! nasty slimy stuff, just like the oil filled condensation build up on many oil fill caps. It literally POURED out lilke a thick soup. SO. I cleaned it all out and stuck the can back in. Certainly was not prepared for that type of stuff to build up in there. Now I gotta take off the front end to clean out the intercooler....again.
Yes, it does.
