Pros and Cons of High Volume Oil Pump

benefits and drawbacks of high volume oil pump

A high volume oil pump enhances lubrication and cooling benefits by increasing oil flow, reducing friction, and carrying away heat during engine operation. However, it may lead to higher oil consumption due to factors like seal wear. The pump also improves oil pressure under heavy loads, providing essential lubrication, preventing wear, and ensuring consistent oil pressure. Yet, it can stress engine components, causing increased friction and potential leaks. Despite these challenges, high volume oil pumps offer vital protection for high-performance engines under extreme conditions. Learn about considerations for street vs. track use in further detail.


  • Enhanced lubrication and cooling benefits for engine components.
  • Potential for increased oil consumption due to higher oil flow.
  • Improved oil pressure under heavy loads for better engine performance.
  • Added stress on engine components from increased oil volume.
  • Better protection for high-performance engines under extreme conditions.

Enhanced Lubrication and Cooling Benefits

By increasing the oil flow rate, a high volume oil pump provides enhanced lubrication and cooling benefits to the engine components. This increased flow rate guarantees that engine parts receive a steady supply of oil, reducing friction and wear.

As the oil circulates more efficiently, it helps to carry away heat generated during engine operation, thereby aiding in the cooling process. Improved lubrication not only minimizes the risk of damage to engine components but also contributes to overall engine performance and longevity.

Furthermore, the enhanced lubrication provided by a high volume oil pump can be particularly advantageous in high-performance or racing vehicles where engines operate under extreme conditions. These conditions often require increased oil flow to maintain peak performance and prevent overheating.

The ability of a high volume oil pump to deliver a higher volume of oil to critical engine parts makes it a valuable component in ensuring the durability and efficiency of the engine, especially in demanding situations.

Potential for Increased Oil Consumption

The increased oil flow rate provided by a high volume oil pump may lead to a potential for increased oil consumption in the engine. Although this enhanced flow can offer benefits such as improved lubrication and cooling, it is essential to take into account the implications it may have on oil usage.

Here are some factors to take into consideration:

  1. Higher Oil Flow: The increased volume of oil circulating through the engine can result in more oil being burned or lost during operation.
  2. Seal Wear: The higher pressure generated by a high volume pump can accelerate wear on seals and gaskets, potentially leading to oil leaks and increased consumption.
  3. Aging Engines: Older engines may be more prone to increased oil consumption when paired with a high volume oil pump due to existing wear and tolerances.
  4. Maintenance Requirements: With higher oil consumption, more frequent oil level checks and top-ups may be necessary to make sure the engine operates well and remains adequately lubricated.

Understanding these potential consequences is important when contemplating the installation of a high volume oil pump to balance the benefits with the potential for increased oil consumption.

Improved Oil Pressure Under Heavy Loads

Enhancing engine performance, a high volume oil pump can improve oil pressure under heavy loads. When an engine is subjected to demanding conditions such as towing heavy loads, climbing steep inclines, or participating in high-performance driving, the increased oil volume provided by a high volume oil pump guarantees that essential engine components receive adequate lubrication.

This improved lubrication helps prevent metal-to-metal contact, reducing wear and tear on the engine components, and maintaining peak performance levels.

Under heavy loads, engines are more prone to experiencing drops in oil pressure due to the increased demand for lubrication. A high volume oil pump addresses this issue by supplying a greater volume of oil to the engine, which helps maintain consistent oil pressure levels even when the engine is working hard.

This consistent oil pressure not only protects the engine from damage but also contributes to smoother operation and enhanced durability, making it a valuable asset for vehicles that frequently operate under heavy loads.

Added Stress on Engine Components

Operating a high volume oil pump can subject engine components to increased stress levels. The higher volume of oil being circulated throughout the engine can lead to a few potential drawbacks:

  1. Increased Friction: The higher flow rate of oil can result in greater friction between moving parts within the engine, potentially causing more wear and tear over time.
  2. Strain on Bearings: Components like bearings may experience more pressure due to the increased volume of oil being pushed through the system, which can lead to premature wear and failure.
  3. Oil Foaming: The rapid circulation of a larger volume of oil can sometimes cause the oil to foam up, reducing its lubricating properties and potentially causing damage to engine components.
  4. Overloading Oil Seals: The higher pressure generated by a high volume oil pump can put additional stress on oil seals, leading to leaks and potential loss of oil pressure within the engine.

It is essential to weigh these potential stress factors against the benefits of improved oil pressure and lubrication when considering the installation of a high volume oil pump in a vehicle.

Better Protection for High-Performance Engines

Providing superior lubrication and oil flow management, high volume oil pumps offer enhanced protection for high-performance engines. High-performance engines operate under extreme conditions, generating increased heat and stress compared to standard engines. The higher volume of oil delivered by these pumps helps to maintain ideal oil pressure levels, ensuring essential engine components receive proper lubrication at all times.

With better lubrication, high-performance engines experience reduced friction and wear on key parts such as the crankshaft, camshaft, and bearings.

Additionally, the improved oil flow management provided by high volume oil pumps helps to dissipate heat more effectively, preventing overheating and potential engine damage. This enhanced protection is essential for high-performance engines that are subjected to intense driving conditions, such as racing or spirited driving.

Considerations for Street Vs. Track Use

When evaluating the suitability of high volume oil pumps for different applications, it is essential to take into account the distinct requirements of street driving versus track use.

  1. Oil Pressure:

Street driving often involves varying speeds and stop-and-go traffic, requiring consistent oil pressure to protect the engine. On the track, higher RPMs and extreme conditions necessitate a pump that can maintain oil pressure under intense stress.

  1. Oil Flow Rate:

Street use typically involves moderate engine loads, where a standard oil pump may suffice. However, track driving pushes engines to their limits, demanding a higher oil flow rate to keep components properly lubricated.

  1. Durability:

Street vehicles may benefit from a high volume oil pump's increased durability and longevity, especially in heavy traffic conditions. On the track, where engines operate at maximum capacity, durability becomes even more critical to prevent catastrophic failures.

  1. Cost and Maintenance:
