If there are any aftermarket add-on that one should add to their vehicles, it should be hands-down, the oil catch can. It is still a mystery why this is not a standard feature in modern vehicles today, as the benefits of having one are clear as day. It easily fits into a car’s crankcase ventilation system. However, the design is less than perfect and oil deposits occur while being carried by air via this venting system. This is where the best oil catch can work its magic.

At its core, the oil catch can is another filter amongst the many in a car engine. There is no fancy mechanism involved as the device relies on gravity to separate the oil from the air. Usually, oil catch tanks will contain steel wool or a baffle system that gases pass through and it separates the oil from the air. The oil that is collected is then fed to the bottom of the catch can until it is cleaned. Direct-injection engine systems benefit greatly from oil catch cans as they inject fuel straight into the cylinders, and an oil catch can is the only way to make sure that your intake is free from oil.

Here’s what you need to know if you are buying an oil catch can

In order to understand how an oil catch can kit can help you maintain your engine in top condition, we need to look at what the problem is first. As combustion occurs in your engine, highly pressurized gases should ideally be released through the exhaust system. This is just the ideal scenario because, in real-world applications, oily air can get into the engine’s cylinders.

When this happens, sludge can build up over time which causes a variety of problems. The oil catch can ensure that only air escapes, trapping the oil into its innards. Among the best oil catch can design allow it to separate the oil from the air, preventing sludge build-up. Not all oil catch can systems are created equal though, and this is where we come in. With that, below are some of the most pertinent information that you absolutely need when choosing an oil catch can for your engine.

Build quality

More often than not you will see words like lightweight when talking about how a good oil catch can is constructed. However, being light is one thing, and being able to withstand the daily wear and tear of being inside the engine bay is another. Look for something preferably made of aluminum, and is not too bulky. Check for how each component fits and make sure there are no discernible gaps in the joints. Some cans are made with both plastic and aluminum. Bottom line is that the catch can feel durable, lightweight, and made of industrial-grade components.

Should include a dipstick

Preferably, a universal oil catch can have a built-in dipstick for checking its oil level. A built-in dipstick should be included as without it you would need to buy one as an addition, adding to the cost. Ensure that the catch can you will purchase has one for your peace of mind.
Installation kit
To be considered as one of the best oil catch can for turbo, the product should have its mounting kit as a standard part of the packaging. Generally, this would be either a mounting bracket or a mounting clamp, or even both for added flexibility. Most good quality oil catch cans would have this hardware included when you purchase them.

Compatibility options

Choosing a ccv catch can that fits a variety of models should be a no-brainer if you are in the market for one. Universal fitment is an important feature for you to consider when choosing an oil catch can for your vehicle to avoid compatibility issues as you install them. No need to worry though as most oil catch can reviews do mention that almost all products have a wide range of compatibility to a wide range of engines.

The size of the catch can itself

Contrary to popular opinion, the size of the oil catch can do not depend entirely on the size of the engine it would be installed in. The size of the ‘can’ itself is also partially dependent on how often you want to clean the can. A small oil catch can will fill up faster and would require frequent cleaning, whereas one with a bigger can will have more time in between cleaning. Your preference, as well as your car’s engine bay, will dictate how small, or how big your oil catch can should be.

The sight tube

A sight tube add-on will allow the user to see the amount of oil inside aluminum catch cans. This is beneficial as you can immediately see if the catch can needs draining at a glance. The caveat is that on a cheap catch can, a poorly made sight tube can be a weak link in the structure and may cause leaks. Make sure to get only good quality catch cans with this feature to avoid problems.


Value for money is something that is often overlooked when choosing because a pcv oil catch can or any oil catch can for that matter, is a relatively cheap investment. However, it is something that should be considered. Those with higher build quality and made with more durable materials are priced higher. Also, look for that one oil catch can that has the right features, such as a built-in dipstick and a sight tube.

Frequently Asked Questions (FAQs):

What happens if the oil can is full?

A filled-up oil catch can cause some oil to go into your crankcase and cause engine stuttering and even misfires. This is why an oil catch can with a dipstick or a sight tube is recommended so you can always see if the catch can needs draining. This does not need to happen often but the recommended interval is every 1000 miles.

Is the oil catch can really needed?

The short and definite answer would be yes. An oil catch can filter is a great preventative measure for worse problems in the long run especially if you have a direct-injection engine. Maintaining the purity and cleanliness of the air coming in from the intakes translate to better fuel economy, engine efficiency, and your engine will thank you for it.

Why don’t cars come with oil catch cans?

This is a hot topic and is still being debated to this day, and the prevalent reasoning is that most car manufacturers will only want to add the bare necessity to keep the car running and that it is good for profit. The certain thing though is that the engine blow-by is real and you need something to keep the oil from reaching your crankcase, and by far only the oil catch can will provide that.

To wrap it up

Prevention is always better than cure and this especially applies to automobiles. The job of the oil catch can is to ensure clean air only gets to the combustion chamber. The fact is, adding an oil catch can filter to your engine will add years to your engine’s life. If you want to enjoy your vehicle and get the most out of it, getting an inside oil catch can is the obvious choice. An oil catch device can keep your engine bay clean and the internal workings free from sludge, dirt, and excess oil for years. The only maintenance that is required will be the occasional draining of the collected oil, a small price to pay to keep your engine running well. Having said this, no amount of gadget will replace due diligence on the driver’s part, as the person behind the wheel is the most important component of any vehicle.
