300ml Oil Catch Can Silver - Universal Baffled PCV Separator

Our review of this 300ml silver oil catch can finds it best suited to drivers who want a simple, durable PCV system upgrade to reduce oil and moisture entering the intake. The biggest reason to buy is the catch can's removable baffled core combined with the option to add steel wool, which clearly improves separation of oil and water vapor and helps prevent carbon buildup over time. Installation is straightforward for most cars, and the included NBR hose and M161.5 threaded ports make a secure connection possible when space allows.

Key Features

• Baffled Design: The removable baffle and ability to add steel wool trap oil and moisture effectively, reducing carbon deposits in the intake system.
• 300ml Capacity: The tank size gives a practical balance of collection volume and compact footprint for compatibility with many engines when installation space is available.
• NBR Fuel Hose Kit: The included NBR hose resists heat and wear, offering a reliable connection for crankcase ventilation lines in everyday driving.
• M161.5 Threaded Ports: Standard inlet and outlet threads provide a secure fit to adapters or hoses and simplify plumbing into the PCV circuit.
• Versatile PCV Compatibility: Can be installed with a breather filter as a vent on pre-PCV systems or inline between PCV hoses as a sealed separator on modern setups.
• Service Support: The seller offers returns and exchanges for quality issues, plus customer service for installation questions.

Who It's For

This catch can is a good match for DIY enthusiasts and owners of turbocharged or naturally aspirated engines who want to reduce oil carryover into the intake and lower the risk of carbon build-up. It works well for compact engine bays that can accommodate a 300ml can and for vehicles where the included 2.6ft NBR hose is long enough to reach mounting points.

It is not ideal for cars with very limited under-hood space or for users who need a larger capacity reservoir for extended oil collection intervals. Also, owners in freezing climates should be prepared to clean the unit more frequently or revert to the original PCV hose when temperatures risk condensation freezing.

Pros & Cons

Pros

• Solid baffled design with removable internals for effective oil and moisture separation.
• Durable NBR hose included for heat and wear resistance during normal service.
• Universal 300ml size balances capacity and compactness for many vehicles.
• Clear compatibility options for both vented and inline PCV installations.

Cons

• Hose length and routing can be borderline on some vehicles, with a few owners needing extra hose.
• Requires weekly checks in freezing conditions to avoid moisture-related blockages.
