The Oil Catch Can Buyer’s Guide
What inside an Oil Catch Can
Does the Oil Catch Can have Filter?
Some oil catch cans have them, and some don't. Now, why would you want one with a filter? Well, a filter medium prevents (or minimizes at the very least) re-entry of the impurities back to the air intake of your engine. You install an oil catch can to get rid of that gunk and sludge, right? Now, you don't want that going back to the system because it defeats the very purpose of installing one.
The absence of any filter medium means that impurities can easily go back to the air intake. Now, you want to have at least a steel wool filter to trap those impurities and send them back to the can. Now, the more expensive models offer brass or bronze filter that disallows re-uptake of collected residue. Bronze and brass filters are more efficient filters because they have low micron pores.

Considering Baffling System
Aside from filters, a baffle is another way to prevent re-entry of impurities back to the air intake. The cheap version may not have them and makes the product inefficient. However, this is an essential part of the oil catch can. Combined with a filter, this accounts for the efficiency of your oil catch can.
About the Can Size
The size of the can may not seem to matter that much, especially if you enjoy regular cleaning and maintenance of the can. So, for people who don’t want to tinker with their oil catch can that often, bigger oil catch can means that you won’t have to open it up as often.
Aside from the volume of fluid, it can store, you also want to check the size to make sure it will fit inside your engine bay. Bigger capacity is helpful, however, if you don’ have space on your engine bay, then it’s impossible.
Drain Port
This is not an essential part of the oil catch can. However, a drain port at the bottom of the can facilitates easy evacuation of the contents. If you don’t have the luxury of time to check and remove the can, a drain port at the bottom will spare you the trouble.
Good to have a Clear Can
Although this criterion is not necessary, it’s nice to have a clear can. Although aluminum and clear cans serve the same purpose, it is satisfying to see know how much gunk and sludge it contains. This way, you won’t have to be guessing if it’s time to drain your can or not.

FAQ
Q: Are oil catch cans really needed?
A: Yes, they are needed because engines have blow-by contents. Preventing oil from getting into the intake system is important to avoid oil slick and poor engine performance.
Q: How do oil catch cans work?
A: These devices are designed to allow air into the intake manifold while limiting oil vapors from entering with the air. Pistons move up and down within the cylinder with combustion getting past the sides and enters the crankcase. The by-product is known as the blow-by.
Q: What are the most common advantages of using oil catch cans?
A: Aside from stopping oil from entering the intake and building up in the can, oil catch cans also separate contaminated oils from the exhaust gases so that they won’t affect the engine. This protects the system from used oils that can choke off your vehicle.
Q: How do oil catch cans improve engine performance?
A: Since oil catch cans don’t add power or create cool noises for car engines, it’s usually overlooked by car owners when modifying or upgrading their vehicles. In reality, the catch can helps in ensuring that your vehicle is always in the running mood. It improves engine performance by simply cleaning the intake system from oil and other unnecessary build-ups.
Q: Do I need to empty my oil catch can? When is the best time to drain it out of oil?
A: During sub-zero climate conditions, it’s important to drain out your oil catch can to avoid build-up which can solidify and be hard to remove. Car owners may opt to remove the can from the system all throughout winter months just to be safe.
Q: What if I did not drain out my oil catch can?
A: The engine normally consumes some oil. However, if you don’t empty the oil catch can, it will eventually build up on the intake while making the engine trip-up when you try to start your car. It’s always important to clean up oil catch cans to keep engines in perfect working conditions no matter the weather conditions.
