RYANSTAR Universal Car Radiator Coolant Tank 800ml
The RYANSTAR option uses 6061 aluminum, delivering strength and corrosion resistance for a long service life. It features an anodized polished finish, enhances durability, and is designed to outperform plastic reservoir tanks. The cap is fully TIG welded and includes an O-ring gasket to prevent leaks. This makes it suitable for buyers who want a tight, rust-resistant reservoir for coolant overflow and oil catch duties in a single unit.
Best for: Enthusiasts seeking a robust aluminum can with a reliable seal. Better for: installations that require a durable, leak-resistant overflow tank. Choose this if: you want a corrosion-resistant aluminum unit with a strong weld and reliable O-ring seal. Caution: The advertised working range is -30° to 120°F; verify compatibility with your vehicle’s cooling system before mounting.
Oil Reservoir Tank Fit DURO Lift Power for Auto Lift
This oil reservoir is positioned for use with automotive lifts and power units. It provides a sizable capacity along the neck area, with dimensions given as Total length about 19.5 inches and a 4.25 inch neck diameter. It will fit most two- and four-post lifts up to 12,000 pounds. It’s best for shop setups where a tall, centralized oil reservoir is required and space allows a longer tank. Limitation: data on the exact material is not specified, so verify compatibility with local lift systems.
EVIL ENERGY Oil Catch Can Kit with Breather Filter
The EVIL ENERGY kit is a compact 300 ml aluminum catch can designed for universal use. It includes a breather filter option and a 0.8 m (2.6 ft) hose with 3/8 inch ID and M16×1.5 thread on the inlet/outlet. It’s best for smaller engine compartments or builds where space is at a premium, and you want a simple PCV-system integration. Limitation: the 300 ml capacity may require more frequent emptying on high-blow-by engines compared with larger cans.
BAGARAATAN 750ML Oil Catch Can Kit
This 750 ml universal oil catch can kit features a two-port baffled reservoir with a drain valve and a breathable filter. The upgraded capacity supports more blow-by capture, reducing oil and moisture that would otherwise reach the intake. Best for: engines that see moderate to high blow-by or owners who want extended intervals between empties. Better for: everyday drivers and lightly tuned engines. Caution: not ideal for turbocharged engines requiring very high-capacity cans; verify fit in tight engine bays before purchase.
PQY Baffled Oil Catch Can Kit Universal 2 Port
The PQY 2-port setup emphasizes a compact design paired with a 50 micron bronze filter to separate oil particles from blow-by gas. The kit defends important components like the intercooler and intake system and helps maintain proper octane levels by reducing potential detonation. Best for: space-constrained engines and those who want a universal, low-profile solution. Limitation: capacity varies with install, so check space in the engine bay before selecting a unit.
Buying Guide
What should you consider when choosing an oil catch reservoir tank?
- Capacity: Decide if you need a compact 300 ml unit or a larger 750 ml–800 ml can based on how often you want to empty the can.
- Material and finish: Aluminum options resist corrosion better than plastics; anodized finishes add durability and appearance.
- Fitting compatibility: Check inlet/outlet thread size (common is M16×1.5) and hose IDs to ensure fit with your PCV hoses and hose clamps.
- Breather filter presence: Some kits include a breather filter for pre-PCV installations; decide if you want filtration flexibility with or without breather options.
- Installation space: Larger tanks require more engine bay room; compact designs suit tight spaces but may need more frequent maintenance.
- Lift and accessory compatibility: If used with a shop lift or specialized equipment, verify that the tank dimensions fit the intended mounting area.
FAQ
- What is an oil catch can and why do I need one? A catch can collects oil blow-by before it reaches the intake, helping keep the intake and intercooler clean and potentially extending engine life.
- Which material is best for durability? Aluminum options are generally more durable and corrosion-resistant than plastic tanks, especially in high-heat environments.
- How do I choose capacity? For daily driving, 300–500 ml cans are common. For tuned or turbocharged engines, 750 ml or more may reduce how often you empty the can.
- What about a breather filter? Breather filters improve venting in some PCV setups, but may require additional mounting considerations.
- Can I upgrade an existing system with any catch can? Most universal cans fit a range of vehicles, but always confirm hose sizes, inlet/outlet threads, and space in the engine bay first.
- Is a can necessary for all engines? Not strictly necessary for all engines, but it can help reduce carbon buildup and improve long-term cleanliness in many modern setups.
