Why you need to change oil filter with every oil change

Changing the oil filter along with the oil during an oil change is crucial for maintaining your engine’s health and longevity. Here are the primary reasons why replacing the oil filter is essential:

1. Removing Contaminants: The oil filter traps harmful contaminants that accumulate in the oil over time, such as metal shavings, dirt, and soot. These contaminants can cause severe wear and damage to the engine’s internal components if they are not removed. Replacing the oil filter ensures that clean oil circulates through the engine, protecting it from these damaging particles.

2. Maintaining Oil Flow: As the oil filter traps contaminants, it can become clogged and restrict oil flow to the engine. This can lead to oil starvation, which can cause engine components to overheat, seize, and fail. Replacing the oil filter ensures that oil flows freely throughout the engine, providing adequate lubrication and cooling.

3. Preventing Bypass Valve Activation: The oil filter has a bypass valve that opens if the filter becomes clogged or the oil flow is restricted. While this valve prevents engine damage, it also allows unfiltered oil to circulate through the engine. Replacing the oil filter ensures that the bypass valve remains closed and that only clean, filtered oil reaches the engine.

4. Optimizing Oil Performance: Fresh oil not only provides lubrication and cooling but also contains additives that enhance its performance over time. These additives can become depleted or contaminated if the old filter remains in place. Replacing the oil filter ensures that the new oil can perform at its best and protect the engine effectively.

5. Cost-effective Maintenance: While it may seem like an extra expense, replacing the oil filter is a relatively inexpensive preventive measure compared to the potential costs of engine damage. Regular oil filter changes can help extend the lifespan of your engine and save you money in the long run.

In summary, changing the oil filter along with the oil is an essential part of maintaining your engine’s health and ensuring its long-term performance. It removes contaminants, maintains oil flow, prevents bypass valve activation, optimizes oil performance, and is a cost-effective maintenance practice.
