Buying Guide
Choosing the right oil filter for your Subaru can seem daunting, but here are a few things to keep in mind:
- Engine Type: Make sure the filter is compatible with your specific Subaru engine (e.g., EJ25, FA20). Check your owner’s manual or online resources for the correct filter number.
- Filtration Efficiency: Look for filters with high filtration efficiency ratings. This indicates how well the filter removes contaminants from the oil.
- Construction Quality: Choose filters with durable construction and a reliable anti-drainback valve. This will prevent leaks and ensure consistent oil pressure.
- Oil Change Intervals: If you plan to extend your oil change intervals, select a filter specifically designed for that purpose. These filters typically have synthetic media and a higher capacity for contaminants.
- Budget: Oil filters range in price from affordable to premium. Consider your budget and the level of protection you need when making your decision.
Also, when you’re changing the oil, make sure you have the correct tools. A good filter wrench is essential! Trust me, I’ve learned that the hard way.
FAQs
Q: How often should I change my oil filter?
A: It’s generally recommended to change your oil filter every time you change your oil. Refer to your Subaru’s owner’s manual for specific recommendations.
