Oil catch cans are essential components for improving engine performance and longevity by preventing oil vapor from entering the intake system. There are several types of oil catch cans available on the market, each designed to suit different needs and preferences. In this guide, we’ll explore the various options, their features, and how to choose the right one for your vehicle.
What Are Oil Catch Cans?
Oil catch cans are devices installed in a vehicle’s PCV (positive crankcase ventilation) system. They capture excess oil vapor and other contaminants before they can reach the engine’s intake manifold. This helps maintain cleaner intake valves, improves fuel efficiency, and prolongs engine life.
Why Use an Oil Catch Can?
- Prevents Carbon Build-Up: By trapping oil and contaminants, catch cans reduce carbon deposits on intake valves.
- Improves Engine Performance: Keeps the air-fuel mixture cleaner, enhancing combustion efficiency.
- Extends Engine Life: Reduces wear and tear on engine components by preventing oil contamination.
Types of Oil Catch Cans
1. Single Chamber Oil Catch Cans
Single chamber oil catch cans are the most basic type. They consist of a single compartment where oil vapor condenses and separates from the air. These are ideal for budget-conscious users and those with naturally aspirated engines.
- Pros: Affordable, simple design, easy installation.
- Cons: Less effective in high-performance applications.
2. Dual Chamber Oil Catch Cans
Dual chamber oil catch cans feature two compartments. The first chamber captures larger oil droplets, while the second chamber filters out finer particles. This design offers better separation and is suitable for turbocharged or high-performance engines.
- Pros: More efficient oil separation, suitable for high-performance vehicles.
- Cons: Higher cost, more complex installation.
3. Vented Oil Catch Cans
Vented oil catch cans include a breather filter that allows excess pressure to escape. These are typically used in race cars or heavily modified engines where increased crankcase pressure is a concern.
- Pros: Reduces crankcase pressure, prevents blow-by.
- Cons: May not be street-legal in some regions, requires regular maintenance.
4. Closed System Oil Catch Cans
Closed system oil catch cans are designed to be completely sealed, preventing any fumes from escaping into the atmosphere. These are ideal for street-legal vehicles and environmentally conscious users.
- Pros: Eco-friendly, compliant with emissions regulations.
- Cons: Can be more expensive, requires precise installation.
How to Choose the Right Oil Catch Can
When selecting an oil catch can, consider the following factors:
- Engine Type: Turbocharged and high-performance engines benefit from dual chamber or vented designs.
- Budget: Single chamber cans are more affordable, while dual chamber and vented options offer better performance.
- Legal Requirements: Ensure the catch can complies with local emissions regulations.
- Installation: Some catch cans require professional installation, while others are DIY-friendly.

People Also Ask
What is the purpose of an oil catch can?
An oil catch can captures oil vapor and contaminants from the PCV system, preventing them from entering the engine’s intake manifold. This helps reduce carbon build-up, improve engine efficiency, and extend the lifespan of engine components.
How often should I empty my oil catch can?
The frequency of emptying an oil catch can depends on the vehicle’s usage and driving conditions. Generally, it’s recommended to check and empty the catch can every 3,000 to 5,000 miles or during regular oil changes.
Are oil catch cans necessary for all vehicles?
Oil catch cans are particularly beneficial for turbocharged and direct-injection engines, which are more prone to oil vapor issues. While not mandatory for all vehicles, they can improve performance and longevity in many applications.
Can I install an oil catch can myself?
Yes, many oil catch cans come with installation kits and instructions, making them suitable for DIY installation. However, for more complex systems or those unfamiliar with vehicle maintenance, professional installation is recommended.
Do oil catch cans affect vehicle warranties?
Installing an oil catch can should not void a vehicle’s warranty as long as it doesn’t alter or damage the original engine components. It’s important to check with the manufacturer or dealer before installation to ensure compliance with warranty terms.
Conclusion
Choosing the right oil catch can depends on your vehicle’s needs, budget, and legal requirements. Whether you opt for a single chamber, dual chamber, vented, or closed system, installing an oil catch can is a smart investment in maintaining engine health and performance.
