Does high performance oil filter make a difference?

12 Apr.,2024

 

There is no need for improved filtration, except when vehicle operates in dusty environments, such as my Jeep does. In a dusty environment improved air filter and oil filter filtration is helpful. So to that end I prefer a high filtration oil filter that filters 10 micron particles (most oil filters only filter 20 or 21 Micron particles).

I like Mobil One oil filters because they filter particles as small as 10 microns. I don't use Mobil One oil, but I do use their filters for this reason. They also flow more/easier than standard paper oil filters. They offer finer filtration AND more flow in OEM size filter, and even more flow in a large oversize filter.

The higher flow and larger the filter, the more time it spends filtering, and the less time it spends in bypass mode. Oil pressure is unaffected (if you choose a filter that has same bypass pressure as OEM filter).

Mobil One filters are already both high filtration and high flow in stock OEM size. The larger oversize M1 filter I use is massive over kill, but cost same as OEM size.

A larger oil filter needs to have the same specs (as OEM size filter) for threads, diameter, bypass valve pressure. Those specs are published at each oil filter manufacturer's website.

No matter what size oil filter you buy, you should always get one with an ANTI-DRAINBACK VALVE because this keeps oil in the filter when engine is turned off. This keeps filter full of oil, which reduces the time it takes for oil pressure to come up at cold start.

The anti-drainback valve should be standard on all filters, but is not. Cheap filters lack an anti-drainback valve. Quality filters (of any brand) have an anti-drainback valve.

So if a larger filter has an anti-drainback valve, being larger won't affect the time it takes oil pressure to come up at cold start.

With any filter, ESPECIALLY A LARGER FILTER, it is important to prime a new oil filter before installing it. Priming the filter prevents (or reduces) dry start after changing the oil.

Here's how to prime a new oil filter before installing it:

If filter mounts thread side up, do this to prime it: Fill up the threaded center hole with oil. Let it sit for a few minutes for filtration material to soak up oil. The oil level in the filter will drop a lot as it soaks up oil. Fill the filter a second time, then install it.

If filter mounts laying on its side, do this to prime it: Fill up the threaded center hole with oil. Let it sit for a few minutes for filtration material to soak up oil. The oil level in the filter will drop a lot as it soaks up oil. Fill the filter up halfway this time time, then install it. It won't make a mess if you quickly tip it into place and spin in on quickly.

The above is how my cousin primes oil filters. He's a mechanic. He primes all oil filters before installing them. However, he exceptionally thorough.

I doubt most mechanics bother to prime oil filters. If a larger than stock filter isn't primed, it's harmful because (if unprimed) it increases the time it takes oil pressure to come up when the car is started after an oil change. That causes a longer lasting dry start than you'd get with an unprimed OEM size filter.

With an OEM size filter, priming it (at time of installation) is very beneficial, but not required. With a substantially oversized filter (like I use) priming the filter is a necessity.

Oil filters play a vital role in maintaining the health and performance of a vehicle’s engine. They are responsible for removing contaminants and impurities from the engine oil, ensuring that only clean oil circulates through the engine components. 

While oil filters are essential for all vehicles, racing oil filters are specifically designed to meet the demands of high-performance racing applications. In this guide, we will delve into the world of racing oil filters, exploring their unique features and highlighting when and why they should be used in racing scenarios. 

Whether you’re a professional racer or an enthusiast looking to optimize your vehicle’s performance, understanding racing oil filters is crucial for achieving peak engine efficiency and longevity. So, let’s dive in and unravel the secrets of racing oil filters.

Understanding Oil Filters 

Oil filters are a critical component in an engine’s lubrication system. Their primary function is to filter out impurities and contaminants from the engine oil, ensuring that it remains clean and free from debris. This is essential for maintaining optimal engine performance and prolonging the life of the engine.

Oil filters typically consist of a metal housing that contains a filter element made of various materials, such as cellulose, synthetic fibers, or a combination of both. As the oil circulates through the engine, it passes through the filter element, which traps contaminants like dirt, metal particles, and carbon deposits. The clean oil then continues its journey to lubricate the engine’s moving parts.

The importance of clean oil cannot be overstated. Contaminated oil can lead to increased friction, accelerated wear, and tear on engine components, and reduced overall performance. Over time, the accumulation of debris can cause engine damage, leading to costly repairs or even engine failure.

To ensure effective filtration, oil filters are equipped with bypass valves that allow oil to flow directly to the engine in case the filter becomes clogged. This prevents oil starvation and maintains lubrication even when the filter is overwhelmed by contaminants.

In standard oil filters, the emphasis is on providing adequate filtration for everyday driving conditions. However, in racing scenarios where engines are subjected to extreme temperatures, high RPMs, and intense loads, standard oil filters may fall short. This is where racing oil filters come into play, offering superior filtration capabilities and enhanced performance to meet the demands of racing engines.

Racing Oil Filters vs. Standard Oil Filters

While standard oil filters are designed to meet the filtration needs of everyday driving, racing oil filters are specifically engineered to excel in high-performance racing environments. Here are the key differences between racing oil filters and standard oil filters.

Construction and Durability

Racing oil filters are built to withstand the rigors of racing conditions. They feature robust construction using high-quality materials that can withstand extreme temperatures, high oil pressures, and vibrations commonly encountered during racing. These filters are often equipped with reinforced housings and heavy-duty filter media, ensuring durability and longevity even in the most demanding racing scenarios.

Filtration Efficiency

One of the main distinctions between racing oil filters and standard oil filters is their filtration efficiency. Racing oil filters are designed for optimal flow rate, which often means reduced filtration efficiency. The filtration media inside these is heavily reinforced and upgraded to withstand high temperatures generated by an engine that is almost constantly sitting on the red line.

However, despite using advanced filtration media, most racing oil filters aren’t any better at filtering debris than your regular premium oil filter. The reason for this is fairly straightforward — racing engines run on oil that is replaced after every race, or every other race depending on the event and type of motorsports. Super fine particles of debris are not a common sight

A racing oil filter is there primarily to catch larger, more dangerous particles and/or fragments that could end up in the oil pan. Preventing those from reaching the engine is vital to keeping the motor alive and reducing the risk of severe engine damage. If you’re thinking about using a racing oil filter on a standard street car, you’re better off going with a regular oil filter.

Oil Flow Rate

In racing applications, maintaining optimal oil flow is crucial. Racing oil filters are designed to offer minimal flow restriction, allowing oil to flow efficiently through the filter. This ensures a constant supply of clean oil to lubricate the engine’s vital components, even under extreme operating conditions. Standard oil filters may have higher flow restrictions, which can limit oil flow and potentially hinder engine performance during racing. Again, this is where these two filter types balance filtration vs. flow rate to cater to their respective use cases. 

Anti-Drainback Valve

Racing oil filters often feature an anti-drainback valve, which prevents oil from draining back into the engine when the vehicle is not running. This feature ensures that the engine receives immediate lubrication at startup, reducing wear on critical components. 

In normal engines, that wouldn’t be an issue since modern commercial engines have the ability to withstand a fraction of the second of oil starvation on start-up. Racing engines are built differently, and that fraction of a second can cause substantial damage over time. Standard oil filters may or may not have this valve, as it is not as critical for everyday driving conditions. 

Capacity and Service Life

Racing oil filters typically have a larger capacity to hold more contaminants before requiring replacement. This extended service life is essential in racing, where the engine is subjected to high-performance demands for extended periods. Standard oil filters, on the other hand, are designed for regular driving conditions and may have a shorter service life due to their lower capacity.

In summary, racing oil filters offer superior construction, enhanced filtration efficiency, improved oil flow rates, and increased durability compared to standard oil filters. These features make racing oil filters a necessity for high-performance racing applications, ensuring maximum engine protection and performance in extreme conditions.

When to Use Racing Oil Filters

Knowing when to use racing oil filters is crucial for optimizing engine performance and protection in racing scenarios. Here are some guidelines for determining when racing oil filters should be employed.

Professional Racing

In professional racing, where engines are pushed to their limits in competitive environments, racing oil filters are a necessity. The intense demands of professional racing require the highest level of engine protection and performance, making racing oil filters the ideal choice.

Modified Engines

If your engine has undergone modifications such as increased horsepower, upgraded turbochargers, or aftermarket components, racing oil filters could be a valuable asset for your build. The increased power output and stress on the engine necessitate superior oil flow to maintain optimal performance and prevent potential damage. However, keep in mind the difference in filtration efficiency and factor that in when creating a long-term maintenance schedule for your engine. 

Track Sessions and Endurance Races

During track sessions, where engines are subjected to prolonged high RPMs and elevated temperatures, racing oil filters excel. Their enhanced oil flow helps maintain consistent lubrication and protects the engine throughout extended periods of intense racing. Similarly, in endurance races that involve extended driving durations, racing oil filters are essential for long-lasting engine performance and protection.

It’s important to note that racing oil filters may not be necessary for everyday street driving or non-performance-oriented vehicles. Standard oil filters are generally sufficient for regular driving conditions. 

Ultimately, the decision to use racing oil filters depends on the specific racing application, level of engine modification, and performance goals. Consulting with experts, professional mechanics, or fellow racers can provide valuable insights and guidance in choosing the right racing oil filter for your particular racing needs.
