How to Do Oil Filter Comparison: Pick the Best Easily

Author: | Posted in Guides No comments

Clean and pure oil is the lifeline for car’s engine, and it is only possible if you’ve installed a proper oil filter in your car. Usually, people ignore this small and inexpensive part of the car, but it plays a vital role in providing clean oil to the engine by trapping all sorts of contaminations from damaging the engine. For proper lubrication and long life, every part of the engine requires clean oil which is possible because of the specialized oil filter.

How to Do Oil Filter Comparison

Goof filter comes with a tough canister which can bear high oil pressure and anti-drain back valve. This valve prevents the dirty, contaminated oil going back into the engine because this is the filtering element which can trap minute particles of dirt and dust. It can also survive hot boiling oil and does not fall apart because of its pressure-relief valve which prevents leakage.
Filter Types:

Sixteen oil filters were studied to figure out and evaluate how they compare and contrast to each other. It will help you to understand whether the higher priced filters offer something special or provide better protection than the others or not and how they are all similar and different from each other. Filter brands including AC Delco, Fram, Bosch, Mobil 1, K&N, Napa, Purolator, Pennzoil, STP, genuine Toyota and Super Tech are reviewed and compared below.

  • Price: Price for these filters fall below $15.

 

  • Parts: Several parts together make an oil filter. The visible parts include outer canister, oil passages and the O-ring. Whereas within the canister, the filter parts include filter elements, pressure relief valve, end caps, core and anti-drain back valve.

 

  • Canister Size: From the outlook, these filters fall into two categories, large canister and small canister. The brands, whose filters are larger in size than others, are STP, K&N, Mobil1, and Toyota filters while all others are almost of the same size. Larger filter size provides bigger storage capacity, thus, trapping more contaminants than others. The downside of the larger filter size is its fitting issues.

 

  • Filter Element: Qualities, which make a filter exceptional, include pore size, the amount of media and material composition. Synthetic media, unlike cellulose media, has uniform porosity. Pores, if too small can be clogged and if too large, they won’t provide better filtration. Usually, filters trap down the particles of around 40 microns (0.002 inches) in size, and the filters with more pleats provide more surface area than the one with fewer pleats.

Core and End Caps:

End caps and core are usually made up of stamped steel. Filter media is wrapped around the core and housed between the end caps. Some manufacturers use plastic cores and cloth or paper end caps to cut the cost which reduces the durability because cloth or paper can disintegrate after becoming saturated. Plastic cores guarantee free and fast oil flow through the filter and their large holes. They quickly reach the engine, but they can collapse under high pressure.

  • Pressure Relief valve (bypass valve): Pressure relief valve, also known as a bypass valve, consists of a plastic or metal valve at one end of the filter element. Its purpose is to bypass the oil from the engine if the filter becomes plugged because of dirt or thick oil.
  • Anti-Drain Back Valve: Its purpose is to hold back the dirt and debris in the filter when the engine is off and prevent it from going back to the oil pan. Usually, they are made up of nitrile or silicone. Silicone is durable, but it is also expensive.

The oil filter parts mentioned above have their respective purposes. Keep them in mind next time you go to buy and choose a good quality filter. Remain concerned about your needs and requirements.
