Oil Catch Can 300ML Baffled Oil Can - Universal PCV Separator

In this review we look at the EVIL ENERGY Oil Catch Can, a compact 300ml baffled unit aimed at drivers who want a simple way to reduce intake and valve gunk. The bottom line: this is a well-made, no-frills oil separator that traps oil and moisture effectively when installed correctly, helping keep intake components cleaner and prolonging engine life. It is best for owners comfortable with basic underhood plumbing and those who value durable hose material and a removable baffle for easy cleaning.

Key Features

• Baffled Design: The removable baffle and included stainless steel wool trap oil and moisture to prevent carbon buildup on intake valves and pistons.
• 300ml Capacity: The tank size is large enough for routine use on most vehicles while still staying compact for tight engine bays.
• Universal Fit: The catch can is designed to fit most cars, provided there is sufficient space for mounting and hose routing.
• NBR Fuel Hose Kit: The supplied 5ft NBR hose with 3/8' ID offers wear and heat resistance for reliable connections over time.
• PCV System Compatibility: It can be fitted with the breather filter for pre-PCV venting or used inline as a sealed can in PCV systems.
• Service Support: The seller offers returns or exchanges for quality issues and responsive customer support if help is needed.

Who It's For

This catch can suits DIY mechanics and enthusiasts who want an affordable way to reduce oil carryover into the intake system and protect direct-injection engines from gumming. It is a practical choice for daily drivers and older engines where extra crankcase ventilation control will improve long-term cleanliness.

It is not ideal for builders who need a vehicle-specific plumbing kit or long lengths of hose out of the box; some owners may need to source extra hose or fittings for unusual engine layouts. Also, drivers in very cold climates should be prepared to inspect or revert to the stock PCV setup in freezing conditions.
