Choosing the right oil catch can for your car involves understanding your vehicle’s needs and the benefits of installing one. An oil catch can prevents oil vapor from re-entering the intake system, improving engine performance and longevity. This guide will help you select the best option by considering key factors like compatibility, capacity, and build quality.
What is an Oil Catch Can and Why Do You Need One?
An oil catch can is a device installed in the crankcase ventilation system to catch oil and other contaminants before they reach the intake manifold. This helps maintain engine cleanliness and efficiency. Over time, oil vapors can accumulate, leading to reduced performance and potential engine damage.
Benefits of Installing an Oil Catch Can
- Improved Engine Performance: Prevents oil vapors from lowering octane levels in the engine.
- Reduced Carbon Build-Up: Minimizes deposits on intake valves, especially in direct-injection engines.
- Extended Engine Life: Reduces wear and tear by keeping the intake system clean.
How to Choose the Right Oil Catch Can
1. Determine Compatibility with Your Vehicle
Before purchasing, ensure the oil catch can is compatible with your vehicle’s make and model. Some catch cans are universal, while others are designed for specific vehicles.
- Check Manufacturer Specifications: Verify if the catch can is suitable for your engine type.
- Consider Engine Layout: Ensure the catch can fits in the available space under the hood.
2. Assess the Capacity and Size
The capacity of an oil catch can is crucial, especially for high-performance vehicles or those driven aggressively.
- Small Capacity: Suitable for daily drivers with moderate oil blow-by.
- Large Capacity: Ideal for performance vehicles or those experiencing significant oil blow-by.
3. Evaluate Build Quality and Materials
A high-quality oil catch can is essential for durability and effectiveness.
- Aluminum Construction: Offers lightweight durability and resistance to corrosion.
- Stainless Steel: Provides excellent strength and longevity.
- Plastic or Composite: More affordable but may not last as long.
4. Consider Additional Features
Some oil catch cans come with extra features that enhance their functionality.
- Baffled Design: Improves oil separation efficiency.
- Drain Valve: Simplifies maintenance by allowing easy disposal of collected oil.
- Sight Tube: Lets you monitor oil levels without disassembly.

Installation and Maintenance Tips
How to Install an Oil Catch Can
- Locate the PCV Valve: Identify the positive crankcase ventilation (PCV) valve and hose.
- Mount the Catch Can: Secure the catch can in an accessible location.
- Connect Hoses: Use the provided hoses to connect the catch can to the PCV system.
- Secure Connections: Ensure all connections are tight to prevent leaks.
How to Maintain Your Oil Catch Can
- Regular Checks: Inspect and empty the catch can every few thousand miles.
- Monitor Oil Levels: Use a sight tube or open the can to check oil accumulation.
- Clean the Can: Disassemble and clean the catch can periodically to maintain performance.
People Also Ask
What Happens if You Don’t Use an Oil Catch Can?
Without an oil catch can, oil vapors can build up in the intake system, leading to reduced engine performance, increased emissions, and potential engine damage due to carbon deposits.
Can an Oil Catch Can Improve Fuel Economy?
While primarily designed to protect the engine, an oil catch can can indirectly improve fuel economy by maintaining optimal engine performance and preventing detonation caused by oil contamination.
Do Oil Catch Cans Void Warranty?
Installing an oil catch can typically does not void a vehicle warranty. However, it’s advisable to check with your manufacturer or dealer, as modifications can sometimes affect warranty coverage.
How Often Should You Empty an Oil Catch Can?
The frequency of emptying an oil catch can depends on driving conditions and vehicle usage. Generally, it’s recommended to check and empty the can every 3,000 to 5,000 miles or during regular oil changes.
Are Baffled Oil Catch Cans Better?
Baffled oil catch cans are generally more effective as they improve the separation of oil from air, ensuring more contaminants are captured before reaching the intake system.
Conclusion
Choosing the right oil catch can for your car involves considering factors such as compatibility, capacity, and build quality. By selecting a high-quality catch can, you can protect your engine, enhance performance, and extend its lifespan.
