What Oil Filter Fits My Car? How to know it?

Car’s engine work on a complicated mechanism with so many things going in the background. From mixing air with fuel to combustion, it is tedious for beginners to understand how it works. However, you can learn about basic things like oil radiators, oil filters, and more. Among all the key things, taking care of an oil filter is crucial for every car owner.

Well, the Oil filters of the car must be changed from time to time. But most people get confused and faces conflicting advice about the oil filters. The owner’s manual, retail clerks, manufacturer and other operators all provide different opinions for your car. When it comes to finding the right oil filter for your car trust the customize advice.

For every car and its owner, a different type of filter is required. So, a single filter can never be the perfect choice for everyone. Which oil filter fits in your car, is mentioned below:

Car Oil Filters

The pore size of the filter

The pore size of the oil filter in your car is the most important factor before considering oil filters. According to the engine builders, smaller particles than 10 microns generate 3.5 times more wear on the engine than the 20 microns. Most of the air filters remove particle sizes of more than 40 microns.

The life of the engine of your car will increases 8 to 12 folds if you choose a good oil filter. So overall, the 30-micron oil filter is the best for every car’s engine. It is reported for both automotive and diesel engines that engine wear was reduced 50 times when a 30-micron filter is used rather than 40 microns.

Dirt holding capacity

Particle capturing efficiency depends on the pore size of the oil filter, same as the dirt- holding capacity also depends on the oil filter. Higher the dirt holding capacity, the higher the service life of the oil filter. It is good to choose an oil filter with higher dirt holding capacity if you drive on dirty roads. In cars, when the oil filter reaches its maximum capacity of holding the dirt, the filter bypasses the oil to the engine without filtering it.

The problem is that the filter doesn’t provide any signal to the owner that the oil filter is chocked by dirt. Most of the brands do not release the dirt holding capacity of the oil filter. It is also too hard to find the dirt holding capacity of the filter on the internet. Dirt holding capacity is too important but you can’t easily compare the filter on this basis.

Pressure flow profile

Most of the people switch the oil filter from the 30 microns to the 10 microns, by the results are not good, the engine plugs more readily and leads to the restricted supply of fuel to the engine. Positive displacement pumps deliver oil to the oil filter and its pressure is proportional to the engine’s speed.

Simply if the engine works on the 3000 rpm its pumps 1 gallon per minute, and respectively pumps 2 gallons per minute at the 6000 rpm. For more simplification, 10 psi pressure increases after every 1000 rpm.

Make sure that the oil filter will face the pressure of the airflow produced by the engine of the car. If the filter is not capable of doing this, choose another filter for your car.


Once you have replaced the car’s oil filter, your car will be offering better mileage and performance. Getting the same work done from a professional mechanic shop can cost you a hefty amount, even you can do the same job at home.

On the other hand, it is also important that you should buy a compatible car’s oil filter. If you end up choosing the wrong filter, it will not fit and if you try hard, there will be an issue with the performance and mileage. We hope that this post helped you learn the easy method of replacing the oil filters.
