What Does an Oil Catch Can Do?

Oil catch cans are simple yet ingenious devices designed to enhance your vehicle's engine performance and longevity. They have evolved significantly since their inception, adapting to the complex needs of modern engines.

Today, they are commonly found in a range of vehicles, from daily drivers to high-performance cars, making oil catch cans a vital component in automotive maintenance.

The Working Principle of Oil Catch Cans

Oil catch cans operate by trapping oil vapors and other contaminants before they can re-enter your engine. These vapors, produced during combustion, are typically rerouted back into the intake system. The oil catch can intercept these vapors, ensuring cleaner air goes back into the engine.

The oil catch can play a crucial role in the crankcase ventilation system. It acts as a filter between the crankcase and the intake manifold. By capturing oil mist and other particulates, it prevents them from harming the engine's performance.

Various types of oil catch cans are available, each designed for specific vehicle needs. Some are straightforward, focusing solely on capturing oil vapor. Others include additional filtering elements to trap finer particles, offering more comprehensive protection.

The choice of an oil catch can depend on your vehicle's specific requirements and your performance goals. Whether you drive a modified sports car or a standard sedan, there's an oil catch can suited for your engine's needs. This choice impacts not only the engine's health but also its efficiency and power output.

Key Benefits of Installing an Oil Catch Can

Installing an oil catch can significantly boosts your engine's performance. It does this by ensuring only clean air enters the combustion chamber, which is crucial for efficient engine operation.

One of the major benefits is the reduction of carbon buildup on intake valves. This buildup can hinder the engine's ability to breathe and perform at its best. An oil catch can trap those oil vapors and particulates, keeping the intake valves clean.

Enhanced fuel economy is another perk of using an oil catch can. It minimizes the amount of oil burned during the combustion process. This leads to more efficient fuel usage and, in turn, can save you money on gas over time.

Oil Catch Can and Engine Longevity

An oil catch can is a guardian for your engine, shielding it from oil vapor and harmful contaminants. These elements, if not controlled, can degrade engine components over time. The catch can capture them, thus maintaining engine integrity.

The presence of an oil catch can potentially extend the life of your engine. It's like having a dedicated defender against the small but harmful particles that can cause wear and tear. This protection is especially crucial for engines operating in harsh conditions or high-performance settings.

Consistent use of an electric exhaust cutout with an oil catch can further enhances engine efficiency. This combination ensures that your engine not only runs cleaner but also more powerfully, adding years to its lifespan.

Regularly maintaining your oil catch can is key to its effectiveness. This involves periodic checking and cleaning to ensure it continues to function as intended. A well-maintained oil catch can is an invaluable asset for prolonging your engine's health and performance.

Oil Catch Cans in Modified vs. Stock Vehicles

Oil catch cans are not just for modified, high-performance cars but equally beneficial for stock vehicles. In modified cars, they're often a necessity due to the higher demands placed on the engine. For everyday vehicles, they add an extra layer of protection and efficiency.

Oil catch cans are part of a larger performance-enhancing strategy in high-performance cars. They work alongside other modifications to ensure maximum efficiency and power. Their role is to keep the engine running optimally, especially under intense driving conditions.

While not subject to the same extremes, stock vehicles still benefit from installing an oil catch can. It's a preventive measure, keeping the engine clean and efficient over time. This is particularly important for vehicles with direct injection engines, where carbon buildup is more common.

Regardless of the type of vehicle you drive, an oil catch can is a smart addition. It's a straightforward way to protect your engine and enhance its performance. Plus, with the right choice, it's a cost-effective upgrade.


Oil catch cans offer numerous benefits, enhancing engine performance and longevity for all types of vehicles. Whether you own a modified speedster or a regular daily driver, integrating an oil catch can be a wise decision for maintaining engine health and efficiency. This small investment keeps your engine running smoothly and contributes to a more economical and environmentally friendly driving experience.
