Features to look in best oil filter

In addition to the fact that it is useful for a motorist to know about the varieties when buying products, there are a few more essential points.

Bypass valve status.

It is difficult to check this moment when buying a product. But if there is an opportunity, be sure to use it. Check if the valve opens at a pressure slightly higher than the upper limit of the relevant value specific to your engine. It will prevent unrefined and dirty oil from entering the motor. The reverse shut-off valve is also checked.

The thickness of the paper for filtration:

The service life of the product directly depends on the thickness. The greater the thickness, the higher the likelihood of quick clogging and quick depletion of the consumable resource.

The maximum operating temperature of the filter:

All motors have different operating temperatures. However, not all consumables can withstand operation in conditions of increased heating. Otherwise, the paper will start to burn out, and the filter will quickly exhaust its capabilities. 

No damage to the case.

Careless assembly, improper transportation, accidental dropping can cause defects to appear on the product. The aspect is secondary when buying a filter, but it's worth checking it out.

Manufacturer.

It is better to trust trusted manufacturers with a good reputation. Buying products from unknown companies are associated with certain risks in the form of rapid wear and tear, poor filtration, etc. Some car owners choose the best oil filters for their cars, only starting from the current ratings. This behavior is the right decision in many ways. But do not forget that the first step is to look at the requirements and characteristics of your motor. And only then compare them with the proposed parameters and capabilities of the oil filter, potentially suitable for you.


Functions of Oil Filter

For modern internal combustion engines to work smoothly, they have to be lubricated first-class. Requirements for engine oil filter increase with increasing engine power and ever longer service intervals. Above all, the quality plays a central role in preventing damage from dirt particles, soot or unburned fuel in the oil.


Clean oil is indispensable for consistent engine performance. That is why oil filters are used: These are intended to clean the engine oil consistently and reliably over the entire service life.


The old and clogged oil filter cannot retain dirt. In the most extreme cases, the oil does not pass right. Then the protection valve opens, letting the unfiltered oil pass through the engine. If you continue driving in these conditions, the dirt particles can cause minor scratches on the metal, causing the engine to fail.


Thanks to new technologies, the frequency of replacing the oil filter are significantly lower than in the past. Choosing a quality guarantees that the filter will maintain its performance up to the mark. The most used engine oil filter is the mechanical one, which cleans the oil thanks to a special type of accordion-shaped paper. In this way, it provides the maximum filtering surface, which retains all impurities and metal residues. There are other types on the market, but they are little used. 


The mechanical filter is divided into two subgroups: external, which is screwed to the monobloc and immersion. The external filter provides more accurate oil filtration. It consists of a cylindrical metal casing containing the filter element. The lubrication system consists of two sections; first, the oil is drawn from the sump and pushed towards the filter, from here through the filter membrane through a bypass valve and arrives in a section with a larger internal diameter, which channels it to the engine.


The second type is an "immersion" in an oil bath and consists of only the filter cartridge. In reality, the design of oil filters is very similar, and it is quite simple. But at the same time, such products have many features and subtleties that must be taken into account when buying a consumable. First of all, it is recommended to look into the operating manual and read what filters and characteristics the automaker suggests for your car.


Types of oil filter

There are 3 categories or types of oil filters.

1- Partially threaded:

They can carry out finer oil purification than outperform the next type. But because of such excellent filtration, the time spent on this process increases. This principle of operation also has positive aspects, since it does not allow pressure drops to occur when the consumable is clogged and contaminated. Also, the partial flow filter prevents pressure drops when the bypass valve is stuck.

2- Full-threaded

Their design provides for the presence of a bypass valve. It is responsible for regulating the oil pressure in the engine lubrication system. The valve's task is to directly protect the gaskets and seals located between the blocks from rupture and damage. The excess pressure is bypassed through the crankcase of the vehicle's power plant.

When the filter is completely depleted, that is, it is completely worn out and clogged, to prevent oil starvation, the filter begins to let the already dirty oil through. It's still better than a lack of lubrication. As a result, the motor can be protected from possible overheating.

3- Combined

The third type of oil filters for automobiles, characterized by extra fine cleaning of the lubricating fluid. The name of the device type makes it clear that the combined filter combines the advantages of the two products presented above and eliminates their disadvantages. Among all types of consumables, these are the most expensive. But they maximize the life of the motor, protecting the rubbing surfaces from wear. Combined filters are especially recommended for machines with increased engine load. Based on the classification, it will be easier for the car owner to make the right choice.



Oil Filters FAQ's

How does the oil filter works?

The oil filter is a must for every type of internal combustion engine. Without it, the engine would not work properly. Every engine, regardless of whether it is a diesel or petrol engine, must be lubricated with oil. The engine oil lubricates all moving parts of the internal combustion engine and keeps them moving. Due to the high heat in the internal combustion engine, the oil is sometimes burned, and this is where the oil filter comes into play. The filter separates the burned engine oil from the remaining lubricants and removes various dirt particles, soot, and small metal chips.

Simply put, the oil filter is responsible for keeping the internal combustion engine clean. Without such a filter, the residues would remain permanently in the engine, and it would stop working much too early. Thus, responsible for ensuring that an internal combustion engine works smoothly for many years. An engine failure goes into the money.

When and why must the oil filter be changed?

The engine oil runs through the filter to clean it of metal debris, dust and combustion residues before it reaches the lubrication points. Engine oil is sucked from the oil sump by the oil pump while the engine is running and passes through the filter with pressure. From there it is pumped to the lubrication points of the engine. 

After prolonged use, the filter clogs with residues. If the filter is not changed in time, the oil can no longer flow through the filter and be cleaned in the process. The engine is still lubricated with a clogged filter as the bypass valve opens and passes as much oil as necessary.

However, it then flows into the engine uncleaned and together with all harmful particles. Therefore, when changing the filter, you should stick to the intervals specified by the vehicle manufacturer.

Do you have to change the oil filter every time you change the oil?

As a rule, the oil filter is automatically replaced with every oil change. You can either have a change carried out in a workshop or, if you have sufficient manual skills, do it yourself. It is imperative that you do not have to replace the filter every time you change it.

Since an oil filter does not cost a lot of money even with higher-quality car models, the replacement should still be carried out. Over time, a small amount of oil will collect in your oil filter. If you only change the oil and not the filter when changing the oil, the residual oil remains in the oil filter. On average, it is half a liter of oil. This waste oil contaminates the new engine oil. That is why most experts advise changing the engine oil and oil filter hand in hand.

When choosing a new oil filter for their car, some drivers believe that they are all structurally the same, sometimes look almost identical, and therefore there is no point in going through many options. You need to take the first one that comes across, focusing purely on the price indicator or manufacturer's recognition.
