Oil Tanks & Accessories

What Are Oil Tanks & Accessories?

Oil tanks and their associated accessories are a foundational part of any engine's lubrication system. Whether you're building a dedicated race car with a dry-sump oiling setup, maintaining a lawn mower or generator, restoring a classic vehicle to factory spec, or managing fluid changes in a professional shop environment, the right oil tank keeps your engine properly lubricated and protected under all operating conditions.

At their core, oil tanks serve as a reservoir for engine oil — but the details matter enormously. Capacity, material construction, baffling, vent design, fittings, and mounting configuration all influence how well a tank performs in its specific application. A performance dry-sump tank, for example, must handle the demands of high-RPM cornering loads, while an OEM small-engine tank needs a precise, leak-free fit to match the original equipment's geometry and fuel flow requirements.

Why the Right Oil Tank Matters

Running an engine with an inadequate or failing oil tank can lead to oil starvation — one of the fastest ways to destroy internal engine components like bearings, camshafts, and piston rings. Even a small crack or ill-fitting replacement tank can introduce air into the lubrication circuit or cause dangerous leaks. For performance builds especially, a purpose-designed oil tank is not a luxury; it's a critical safety and reliability component.

Accessories in this category — including tank fittings, breather caps, mounting brackets, and drain accessories — are equally important. They ensure the tank integrates correctly with your vehicle's or equipment's oil circuit, maintains proper venting, and allows for clean, efficient fluid management during maintenance.

Key Considerations When Shopping Oil Tanks & Accessories

• Application type: Performance/racing dry-sump systems, OEM small engine replacements, and shop fluid management equipment each have distinct requirements.
• Capacity: Match the tank volume to your engine's oil volume needs and any reservoir requirements of your lubrication system.
• Material: Aluminum tanks are common in racing for their light weight and heat dissipation; plastic OEM tanks prioritize corrosion resistance and exact fitment.
• Fitment: Always verify compatibility by engine model number, especially for OEM replacement parts.
• Accessories: Consider what fittings, vents, and mounting hardware are included or needed separately.
