Bypass oil filters are supplementary filtration systems used in conjunction with primary full-flow filters in engines and machinery. They address the issue of full-flow filters allowing smaller, harmful particles to pass through by filtering a small portion of the oil at a time, removing finer contaminants. This dual filtration system significantly improves overall oil cleanliness, providing better engine protection and extending oil and engine life. AMSOIL offers two types of bypass systems: single-remote and dual-remote. While bypass oil filters are more expensive, they last longer and provide improved engine protection, making them a valuable investment for prolonging engine life.
Characteristics and Values of a Bypass Fuel Filter
| Characteristics | Values |
|---|---|
| Purpose | To filter out smaller, harmful particles that pass through the primary full-flow filter |
| Mechanism | A portion of the oil is diverted from the main flow into the bypass filtration system, where the smaller particles are filtered out |
| Pressure Regulation | Typically, 10% or less of the total oil flow passes through the bypass filter to prevent pressure drop that could harm the engine |
| Filtration | Removes particulates as small as a few microns, improving oil cleanliness and reducing engine wear |
| Return to Engine | The cleaned oil is returned to the engine/machinery oil sump and recirculated through the system |
| Continuous Operation | The filtration process repeats continuously as the engine runs, gradually filtering all the lubrication oil |
| Environmental Benefits | Reduced oil changes result in less waste and cleaner oil, which can decrease fuel consumption and emissions |

What You'll Learn
Bypass oil filters are a supplementary filtration system
The bypass filtration process involves diverting a portion of the oil from the main flow into the bypass filter, where the smaller, more harmful particulates are removed. Centrifugal filters are particularly effective in this regard, capable of capturing microscopic particles as small as a few microns. This filtration step ensures that only clean oil is returned to the engine sump and recirculated through the system.
The enhanced filtration provided by bypass oil filters offers several benefits. Firstly, it reduces harmful particulate buildup and minimizes wear on critical engine components, leading to improved engine protection and reliability. Secondly, cleaner oil translates to reduced frequency of oil changes, resulting in lower maintenance costs and longer intervals between oil drain intervals. Additionally, bypass oil filters contribute to sustainability initiatives by reducing oil waste and promoting smoother engine operation, which can decrease fuel consumption and emissions.
Bypass oil filters are designed to work alongside full-flow filters, providing comprehensive wear protection against both large and small particles. This dual-filter setup increases overall filter capacity and extends the life of the filters. The installation of bypass filters is relatively straightforward, and they are available in single-remote and dual-remote configurations to suit different engine compartment layouts.

They remove smaller, harmful particles
Bypass oil filters are supplementary filtration systems used in conjunction with primary full-flow filters in engines and machinery. While full-flow filters are capable of capturing larger particles as oil circulates through the engine, they are less efficient at capturing smaller, harmful particles, which can cause wear and damage to the engine.
Bypass oil filters address this issue by filtering a small portion of the oil at a time, allowing for the removal of finer contaminants that full-flow filters cannot capture. This dual filtration system significantly improves overall oil cleanliness, providing better engine protection and extending oil and engine life.
Bypass filters have a high-pressure differential, causing oil to flow through them very slowly, which aids in the removal of smaller contaminants. They are highly efficient at eliminating nearly all contaminants, including microscopic particles and soot, from motor oil.
By removing these abrasive, finer contaminants, bypass oil filters protect engine components, enhance reliability, and reduce the likelihood of unexpected maintenance needs. They also help to reduce maintenance costs by minimising the need for frequent oil changes and part replacements.

They improve engine protection and extend engine life
Bypass oil filters are supplementary filtration systems used in tandem with primary full-flow filters in engines and machinery. They enhance engine protection and extend engine life by eliminating abrasive particles, thereby protecting engine components and enhancing reliability.
Full-flow filters are more open and free-flowing than bypass filters, allowing them to efficiently lubricate the engine. However, due to their free-flowing nature, they are less effective at removing small, harmful particles. Bypass oil filters address this issue by filtering a small portion of the oil at a time, capturing and removing finer contaminants that full-flow filters cannot. This dual filtration system significantly improves overall oil cleanliness, ensuring better engine protection and prolonged engine life.
Bypass filters have high capacities and can eliminate much smaller particles, including soot and microscopic particles. They operate by drawing approximately 10% of the oil pump's capacity at any given time, trapping and removing extremely small, wear-causing contaminants. The denser and more efficient filtration media in bypass filters provides improved small-particle removal, with some filters achieving up to 98.7% efficiency in removing contaminants down to 2 microns.
By removing these fine contaminants, bypass filters improve engine reliability and performance. They also contribute to environmental sustainability by reducing the need for frequent oil changes, resulting in less oil waste and cleaner oil. This, in turn, promotes smoother engine operation, reducing fuel consumption and emissions, which benefits the environment.

They reduce maintenance costs
Bypass oil filters are supplementary filtration systems used in tandem with primary full-flow filters in engines and machinery. While full-flow filters are more open and free-flowing, bypass oil filters capture finer, more abrasive contaminants, including microscopic particles. Bypass filters operate by filtering oil on a "partial-flow" basis, drawing approximately 10% of the oil pump's capacity at any one time. This dual filtration system significantly improves overall oil cleanliness, extending oil and engine life.
Bypass oil filters are instrumental in reducing maintenance costs by minimising the need for frequent oil changes and part replacements. They also improve engine protection and reliability by eliminating abrasive particles, thereby enhancing reliability and reducing the likelihood of unexpected maintenance needs.
Additionally, bypass oil filters can increase engine uptime and efficiency, leading to improved production. They also offer environmental benefits, as fewer oil changes result in less oil waste and cleaner oil, promoting a smoother engine operation that decreases fuel consumption and emissions.
Furthermore, bypass filters can be particularly beneficial for antique vehicles, as they help keep the gasoline cool and prevent it from turning into vapour, which could block the flow of fresh gasoline to the carburetor. This recirculating fuel system is a simple solution to ensure the engine receives an uninterrupted supply of fuel, reducing the need for maintenance interventions.

They improve overall oil cleanliness
Bypass oil filters are supplementary filtration systems used in conjunction with primary full-flow filters in engines and machinery. They improve overall oil cleanliness by filtering out smaller contaminants that full-flow filters cannot. This dual filtration system significantly improves overall oil cleanliness, providing better engine protection and extending oil and engine life.
Full-flow filters are only capable of capturing larger particles as oil circulates through the engine, allowing smaller, harmful particles to pass through. Bypass oil filters address this issue by filtering a small portion of the oil at a time, typically around 5%-10% of the oil pump's capacity, and trapping these finer contaminants.
Centrifugal bypass filters, in particular, are highly efficient at removing microscopic particles from lubrication oil. They utilize centrifugal force to separate and collect particulates as small as a few microns, ensuring that cleaner oil circulates back through the engine. This gradual process repeats continuously as the engine runs, eventually making all the oil analytically clean and reducing harmful particulate buildup.
By removing these fine contaminants, bypass filters minimize wear on critical engine components, reduce maintenance costs, and extend the lifespan of both the oil and the engine. Cleaner oil also promotes smoother engine operation, decreasing fuel consumption and emissions, resulting in environmental benefits.
