How To Choose The Right Oil Filter For Your Car

When it comes to oil filters, car owners sometimes receive conflicting information. You can find different opinions in-vehicle owners’ manuals, installers, quick-lube operators, mechanics, and store clerks. The truth is that when it comes to oil and filters, the only correct solution is designed for specific needs.

There is no such thing as a one-size-fits-all solution for oil filters, so this article will tell you How To Select The Best Oil Filter For Your Car.

Clean Oil Expectation

The influence of solid contamination in diesel and gasoline crankcase oils on engine dependability has been thoroughly researched. Particle pollution can affect fuel efficiency, lubricant life, environmental concerns, and wearing and performance. Drivers who use excellent filtering procedures usually claim longer service life and lower maintenance costs. While several advantages to using clean oil, low-quality filters are commonly used in diesel engines.

Your Engine’s Worst Enemy Is Silica

The majority of pollutants are potentially harmful such as water, glycol, gasoline, and incorrect oil,… Solid pollutants are typically thought to be the most harmful. After oxygen, silicon is the second most abundant element on the earth. In the form of natural soils and terrain dust, silica and silicates make up a significant amount of the earth’s crust. 

Dust contamination of lubricating oil is widely recognized as the most harmful to engine surfaces. The most common way for terrain dust to enter an engine is through the air intake. The rest comprises extremely minute particles that get through the air filter. 

The first step in preventing particle-induced wear and failure is to take all reasonable precautions to keep dust out of the engine compartment. The next critical goal is to choose the right oil filter.

Oil Filter Choice 101

The most important aspects to consider when choosing an oil filter:

  • Size and Capture Productivity
  • Capacity to Hold Dirt
  • Pressure-Flow
  • Integrity in Design and Fabrication

Methods For Testing Oil Filters

The two most essential test standards are SAE HS 806 and SAE J1858. The SAE HS 806 standard, which originates from the 1950s, is divided into several sections and chapters:

  • Limitation to Flow
  • Characteristics of Full-Flow Oil Filters in Terms of Capacity and Contaminant Removing
  • Particle Retention Capability Test with a Single Pass
  • Test of Media Migration
  • Lube Oil Elements Collapse Test
  • Test for anti-drain valves in the inlet and outlet
  • The capable of adapting to changing situations in the environment
  • Installation and Dismantling
  • Mechanical Examinations
  • Performance of the Relief Valve

The SAE J1858 standard is more relevant, while the newer SAE J1858 uses online automated optical particle counters.

Performance characteristic accounts for a significant portion of the extra price you’ll pay for superior oil filtering.

Capacity To Hold Dirt

The dirt-holding capacity reveals information about the filter’s service life before it goes into bypass.

Car oil filters have no indication that tells you when oil is bypassing and not being filtered. The ideal oil filter replacement interval, like the oil change interval itself, is mostly guesswork, necessitating the use of an adequate safety buffer.

We could not locate any information on the dirt-holding capacity of motor oil filters. However, there’s a strong probability that if we phoned these filter firms’ toll-free customer service numbers, we could receive the information we needed.

All filters work equally well on this property. However, we should point out that we have been evaluating automobile oil filters for more than ten years. All filters are not created equal when it comes to dirt-holding ability.

Pressure-Flow Profile

Positive-displacement pumps supply flow to the oil filter and the engine at a rate proportional to the engine’s speed. Regardless of the pressure limitation, the pump will provide the flow. As the flow rate rises, so does the pressure.

The engine would have to stall, the filter would have to explode, or the pump gears would strip in such an improbable scenario. On the other hand, unexpected bypass flow might happen if an oil filter stops prematurely owing to a high flow limitation.

Unfortunately, aftermarket oil filter information is nearly as tough to come by as dirt-holding capacity. However, the major manufacturers of motor oil filters are well aware of the importance of filter pressure-flow characteristics and typically build filters that reach or beyond realistic limitations in regular usage.

Integrity In Design And Manufacture

Many of the businesses manufacture oil filters for automakers, oil companies, mass merchandisers, auto parts stores, and quick-lube businesses. A detailed examination of the shape and structure of the can and the baseplate generally disclose the maker.

An oil filter may be opened and dismantled. The following are some things to keep an eye out for:

  • Materials for Construction
  • Side-Seam of Filter Media
  • Pleat Density and Support
  • Valve Seats
  • End-Cap Adhesive 

Is A Premium Oil Filter With High Capture Efficiency Right for You?

Although the filter is described as deluxe, high-performance, super-efficiency, or darn-good on the packaging, it doesn’t imply you’re receiving a premium product.

Many of the same factors that encourage us to purchase synthetic motor oil also apply to premium oil filters. Let’s go through the list again:

  • Engines with High Performance
  • High-Performance Driving (HPD)
  • Engines in Luxury Cars
  • Extreme Cold Starts
  • Longer Oil Drains
  • Towing and High Loads
  • Long Engine Life
  • Low Viscosity

How Often Should Your Oil Filter Be Replaced?

Many installers and component retailers recommend replacing the oil filter with every other oil change. 

Late-model automotive engines use smaller filters to save weight, money, and space. They might be difficult to locate and contact at times. A smaller oil filter has less cumulative dirt-holding capacity and perhaps higher flow restriction.

If your oil filter becomes clogged before it is replaced, the oil will bypass, causing your engine to wear out faster. When your filter enters bypass mode, it stops operating.

A Note About Oil Filter Mounts

If you install an oil filter with SAE threads on an engine that requires metric threads, you risk damaging the threads that hold the oil filter in place, which might lead to leaks. The oil filter might also become loose due to mismatched threads. This would cause an abrupt loss of oil pressure and the whole oil charge.

Regular Oil Vs Synthetic

Regular oil is a natural mineral-based substance with a wide range of molecular sizes. The image is provided by these ball bearings. Consider attempting to slide on them!

Conclusion

What are your engine’s greatest enemies? It’s tiny dirt particles that can’t be seen with the naked eye. This is why oil filtering is so important. These oil filters increase engine protection in general. Oil change intervals and selecting a high-quality oil filter are critical to keeping your internal engine parts in good working order for the duration of the engine’s life. As a result, always check your vehicle’s owners’ handbook for compatibility and warranty information about How To Select The Best Oil Filter For Your Car.
