I wanna add an oil catch can to my car not a blowby valve that irish has but something that will hold another quart of oil in my car. I remember hear the benifits dont really reember them but one wat the oil intervals are longer. I drive like 300+ miles a week so it would be nice ya know

 

Go on Ebay and get one of their catch cans...they work great and very cheap...the can is very large and I'm sure it won't have to be dumped until years later...I drive alot of city milles and my ebay catch can isn't even 1/8th full yet....this is about 4 months and 4-5k miles ever since I installed it

 

Is this what you are refering to?

oil accumulator

These will only help with a sudden loss of oil pressure, or to prevent "dry" start-ups.

If you are looking to add more usable oil capacity then either of these could be a solution

added oil capacity

or

oil pan

or

oil pan2


The above were designed for the 350z, however they might work on the Maxima as well. Some research required, albeit with reduced ground clearance.
