RULLINE 350ml Universal Oil Catch Can - Baffled Reservoir for Engines

In this review of the RULLINE 350ml Universal Oil Catch Can, the bottom line is simple: it is for car owners who want a compact, well-built baffled reservoir to reduce oil and moisture entering the intake system and protect engine internals. The catch can's biggest selling point is its combination of a welded 0046 aluminum body and internal baffle design that captures oil effectively while remaining lightweight and corrosion resistant. Installation is straightforward for most vehicles thanks to the included adapters and bracket, making it a practical upgrade for routine engine maintenance.

Key Features

• 350ml Capacity: The moderate 350ml reservoir size provides meaningful oil and moisture collection without taking excessive underhood space.
• Universal Fit: Comes with three types of adapters and a 31.5in hose to fit a wide range of vehicles including Subaru, Honda, Toyota, Ford, Nissan and Dodge models.
• Baffled Design: Internal baffling improves oil separation so more oil and blow-by condensate are retained in the tank rather than returning to the intake.
• Quality Construction: Made from 0046 aluminum and fully TIG welded for strength, durability and resistance to corrosion under normal engine bay conditions.
• Good Sealing: Fittings include O-ring gaskets to limit leaks and maintain a sealed catch can system under crankcase ventilation pressures.
• Oil Dipstick: A dipstick is supplied for convenient fluid level checks without unscrewing the unit each time.

Who It's For

This RULLINE catch can is best for enthusiasts and everyday drivers who want to reduce carbon and sludge buildup in the intake and prolong engine life, especially on older or higher-mileage engines that suffer from PCV/CCV oil migration. It also suits DIY installers who prefer a tidy, compact reservoir with included brackets and adapters.

Drivers who need a heavy-duty racing solution, very large capacity reservoirs, or who require hardened braided hoses out of the box may want to consider other specialist options; some customers reported the supplied hoses as weaker than the metal build of the tank itself.
