Taking care of your car is important. The question is how to do it. Should you change the engine oil along with the filter? How often should the engine filter be replaced? What is its function? And how should you choose it? Today, we will use an article to help you clarify everything thoroughly, making car maintenance clear and understandable.

PART 01

What is the oil filter? The "guardian" of the engine

In simple terms, the oil filter (engine filter) is the "water purifier" of the engine's lubrication system.

When the engine is running, the engine oil circulates internally for lubrication. During this process, metal shavings, carbon deposits, dust and other impurities are produced. If not filtered, these "grinding agents" will accelerate the wear of the parts and harm the engine.

The core mission of the filter: to intercept these harmful impurities, allowing clean engine oil to continuously provide lubrication, cooling and cleaning for the engine, thereby extending the engine's lifespan.

PART 02

The internal composition and structure of the machine filter

The machine filter is usually composed of a housing, filter paper, sealing ring, check valve, bypass valve, spring, etc.

Its working principle is as follows: The oil pump delivers pressurized oil to the oil filter. After passing through the filter paper to remove impurities, the clean oil flows to various lubrication areas of the engine.

PART 03

Why is it necessary to replace the engine oil along with the engine filter?

The old filter element is saturated: The internal part of the old engine filter has already absorbed a large amount of impurities and oil sludge, resulting in a significant decline in its filtering capacity.

Avoid "New Oil Becoming Old Oil": If the machine filter is not replaced, the newly added clean oil, once circulated, will immediately be contaminated by the dirt in the old filter element. As a result, the effectiveness of this oil change will be greatly reduced.

Prevent bypass valve from opening: When the filter becomes clogged to a certain extent, the bypass valve in the machine filter will be forced to open, allowing the engine oil to bypass the filter and enter the engine directly (to avoid running out of oil), but this is equivalent to allowing dirty oil to directly damage the core components.

PART 04

When to replace? Remember a rule

Generally, when changing the engine oil, the oil filter must also be replaced at the same time.

By mileage: Refer to your recommended oil change mileage (such as 3000 or 5000 kilometers).

By time: Even if the mileage has not reached the limit, if the interval for oil change has exceeded half a year or one year, it should also be replaced at the same time.

PART 05

How to Choose a Good Machine Filter? Check These Three Points

Selecting a high-quality machine filter is crucial for effective maintenance. Don't just focus on the price; also pay attention to the quality:

Check the filter paper material: Good filter paper has high fiber density and uniformity, strong dust absorption capacity, high filtration accuracy, and can ensure smooth oil flow. Poor-quality filter paper has poor filtering effect and is prone to damage.

Inspect the sealing gasket: Press the rubber sealing ring at the top of the filter with your hand. A high-quality gasket is soft and elastic, ensuring a tight seal and preventing oil leakage. A poor-quality gasket is hard, stiff, and has poor elasticity, posing a risk of oil leakage.

Check the internal process: The filter element inside the high-quality machine filter is firmly fixed to prevent it from shifting during the impact of the engine oil and the jolting of the vehicle. This ensures that all the engine oil passes through the filter paper for filtration. You can shake it and listen to see if there are any obvious loose or abnormal sounds inside.

Although the oil filter is small, its responsibility is significant. It is like the "kidney" of the engine, and regular replacement is necessary to remove the "toxins". Choosing a reliable filter for your car is the most sincere guarantee for the engine.
