If you want a racing oil catch can with drain valve-style cleanup in a compact package, this EVIL ENERGY 300ml setup is aimed at keeping PCV blow-by from building up in the intake.

Drain-Valve Convenience Pick – 750ml Baffled Reservoir with Drain Valve

This racing oil catch can with drain valve is built around convenience, thanks to its included drain valve and large 750ml reservoir. The baffled tank is intended to catch oil and moisture from PCV/CCV air, and the aluminum construction is meant to resist rust, scratches, and corrosion for longer-term use on most cars.

How We Picked These Racing Oil Catch Can with Drain Valve Options

We looked for kits that balance airflow control, separation efficiency, and simple serviceability. Priority went to baffled designs, durable aluminum construction, and drain-valve access that makes emptying collected oil cleaner and faster. We also favored kits with useful fittings or hose hardware so installation is less guesswork.

Quick Comparison

For most buyers, the biggest differences are can size, port layout, and included accessories. Smaller cans can fit tighter engine bays, while larger tanks reduce how often you need to drain them. Dual-port and 2-port designs are usually better for flexible routing, especially on custom or modified setups. Kits with hoses, adapters, or breather filters may cost more but can save time during installation.

Key Buying Factors for Racing Oil Catch Can with Drain Valve

Capacity and Packaging

Match the can size to your engine’s blow-by volume and available space. A compact 150ml to 300ml unit can work well for limited bay space, while 750ml to 1.2L options are better if you want longer service intervals or run a more aggressive setup.

Baffling and Separation

Baffled internal design matters more than cosmetic finish. Good baffling helps slow and condense oil mist before it reaches the intake tract, which is especially important on turbocharged, high-RPM, or track-driven vehicles.

Drain Valve Access

A drain valve should be easy to reach and secure enough not to leak. If you service the car often, this feature is a major convenience because it avoids removing the entire can for routine emptying.

Fittings, Hose Size, and Compatibility

Check port size, hose diameter, and adapter count before buying. Universal kits can fit many vehicles, but the best match still depends on your PCV routing, engine bay space, and whether you need a breather-style or closed-loop setup.

Who Should Buy Which Racing Oil Catch Can with Drain Valve?

Choose a larger baffled catch can if you want fewer drain cycles and have room for a bigger tank. Choose a compact universal kit if fitment is tight or you mainly want a straightforward PCV upgrade. If you’re building for performance use, prioritize baffling, strong fittings, and easy draining over extras you may not need. For daily drivers, a cleanly packaged universal kit with a drain valve is usually the best mix of convenience and protection.
