- Manufacturer's Recommendation: Always start by checking your owner's manual. Some manufacturers indeed suggest changing the oil filter with every alternate oil change. However, this recommendation often depends on the specific model and its engine design.
- Cost vs. Benefit Analysis: Oil filters are relatively inexpensive compared to potential engine repairs. Changing the filter every oil change can be seen as an affordable way to ensure better engine health.
- Driving Conditions: If you often drive in harsh conditions (like dusty environments, frequent short trips, or heavy traffic), it’s safer to change the filter with every oil change. These conditions can lead to quicker accumulation of contaminants.
- Oil Change Interval: Modern cars with longer oil change intervals (e.g., 10,000 miles or more) should definitely have the filter replaced each time. Older models with shorter intervals (like 3,000 miles) might not require as frequent changes.
- Quality of Oil Filter: Higher quality filters can sometimes last through two oil changes, but it's crucial to ensure they are designed for extended use.
- Peace of Mind: Many drivers and mechanics prefer changing the oil filter every time for peace of mind. It ensures maximum cleanliness and efficiency of the oil system.
