After researching manufacturer specifications, industry standards, and aggregated owner feedback, we evaluated the top oil catchers for cars. An oil catch can separates oil vapor from crankcase gases before they re-enter the intake, reducing carbon buildup and improving engine longevity. Our comparison focuses on build quality, filtration efficiency, ease of installation, and value. Here are the seven best options for most vehicles.

1. Mishimoto Universal Baffled Oil Catch Can: Top Pick
The Mishimoto Universal Baffled Oil Catch Can is our top pick after comparing its internal baffle design and anodized aluminum construction. Owner feedback consistently reports minimal oil bypass and easy mounting. The 3/8 inch NPT ports fit most PCV systems without adapters.
However, its 4-ounce capacity is smaller than some competitors, meaning drivers with heavy blow-by may need to empty it every 1,000-2,000 miles. Skip this if you prefer a larger reservoir or need a direct-fit kit for a specific model.
- Internal baffle prevents oil slosh and re-entrainment
- Machined from 6061 aluminum with CNC-cut ports
- Includes mounting bracket and hose fittings
Pros: High build quality and leak-free seals; Effective at trapping oil vapor even under high boost
Cons: Small capacity may require frequent emptying on high-mileage vehicles
2. RXP Universal Oil Catch Can: Best Value
The RXP Universal Oil Catch Can offers excellent value with its sight tube and baffled design. We found owner feedback praising its easy installation and effective oil trapping. The aluminum body is lightweight and resists corrosion.
One downside: the sight tube may yellow or fog after extended use, making it harder to read. If you need a long-term clear view, consider a model with a metal dipstick instead.
- Sight tube shows collected oil level
- Baffled internal design for better separation
- Includes hoses and clamps for basic installation
Pros: Transparent sight tube makes monitoring easy; Affordable without sacrificing core features
Cons: Sight tube can discolor over time, reducing visibility
3. JEGS Baffled Oil Catch Can: Best for High Performance
The JEGS Baffled Oil Catch Can is built for performance applications. Its 1-quart capacity and -10 AN fittings suit turbo or supercharged engines. We evaluated owner reports of effective oil separation even under sustained high RPM.
The steel body is robust but adds weight, which may not be ideal for weight-conscious builds. Also, the powder coat can chip if mishandled. Skip this if you need a lightweight or compact can for a daily driver.
- Large 1-quart capacity reduces emptying frequency
- AN fittings compatible with high-flow systems
- Steel construction with durable powder coat
Pros: Handles high blow-by volumes from forced induction engines; Easy to mount with included bracket
Cons: Heavier than aluminum alternatives
4. EVIL ENERGY Oil Catch Can: Compact Design
The EVIL ENERGY Oil Catch Can is a compact option for vehicles with limited space. Its sight glass is useful, and the baffled design works adequately for moderate blow-by. Owner feedback notes easy installation in tight spots.
However, its small capacity means more frequent emptying. If you have a high-mileage engine or drive hard, you may need to check it often. Consider a larger can if convenience is a priority.
- Small footprint fits tight engine bays
- Sight glass for oil level monitoring
- Includes mounting bracket and hardware
Pros: Fits in cramped spaces where larger cans won't; Decent build quality for the price
Cons: Small capacity (about 3 ounces) fills quickly
5. GZ Motorsport Oil Catch Can: Direct Fit for Subaru/Toyota
The GZ Motorsport Oil Catch Can is designed to bolt directly onto Subaru and Toyota boxer engines. Owner feedback highlights the hassle-free installation and effective oil trapping. The stainless steel mesh adds extra separation.
But if you don’t own one of the listed models, this can won’t fit without modification. Also, the hoses are pre-shaped, so they may not work with aftermarket intake setups. Skip this for universal applications.
- Pre-bent hoses for specific engine bays
- Baffled design with stainless steel mesh
- Includes all necessary hardware
Pros: No cutting or custom hoses needed for listed models; Easy bolt-on installation
Cons: Limited to specific vehicle applications
6. CatchCans.com Standard Baffled Can: Budget Pick
The CatchCans.com Standard Baffled Can is a budget-friendly entry. It provides basic oil separation for stock or lightly modified engines. Owner feedback indicates it catches some oil but not as much as premium options.
The painted steel can rust if scratched, and the internal baffle is less refined. If you have a high-performance engine or want maximum filtration, invest in a higher-end model. This is best for cost-conscious owners with low blow-by.
- Low price point for basic oil separation
- Baffled internal design
- Includes mounting bracket
Pros: Very affordable; Simple design works for light blow-by
Cons: Paint may peel over time; Not as effective as more expensive baffled cans
7. Vibrant Performance 11401 Oil Catch Can: Premium Build
The Vibrant Performance 11401 Oil Catch Can is well-made but lacks a baffle. In our evaluation, this means it relies solely on gravity and condensation, which is less effective than baffled designs. Owner feedback confirms it catches less oil than similarly priced baffled cans.
It also has a small capacity. Unless you prioritize aesthetics over function, we recommend a baffled can. Skip this if you want maximum oil trapping or have a high-blow-by engine.
- Clear anodized finish resists corrosion
- Machined from billet aluminum
- Includes mounting bracket
Pros: Attractive appearance; Solid machining quality
Cons: No internal baffle reduces separation efficiency; Small capacity
Frequently Asked Questions
Do oil catch cans really work?
Yes, when properly installed, an oil catch can reduces the amount of oil vapor entering the intake manifold. This helps prevent carbon buildup on intake valves, especially in direct-injection engines. However, effectiveness varies by design; baffled cans generally perform better than non-baffled ones.
How often should I empty my oil catch can?
It depends on your engine’s blow-by and driving conditions. Check every 1,000 to 3,000 miles. High-performance or high-mileage engines may need more frequent emptying. A sight tube or dipstick makes monitoring easier.
Will an oil catch can void my warranty?
Potentially, if it causes damage or is installed incorrectly. Many aftermarket catch cans are reversible, but any modification can be questioned. Check your warranty terms and consider a direct-fit kit to minimize risk.
Can I install an oil catch can on any car?
Most cars with a PCV system can accommodate a universal catch can, but you may need adapters or custom hoses. Direct-fit kits are available for popular models like Subaru WRX, Ford Mustang, and Toyota 86. Always verify fitment before purchasing.
What is the difference between baffled and non-baffled catch cans?
A baffled can has internal walls or mesh that force oil vapor to condense and drip down, improving separation. Non-baffled cans rely on gravity alone and are less effective. For best results, choose a baffled design.
