Oil Filter Buying Guide
Last updated: 24 April 2026
The oil filter traps contaminants and metal particles to keep your engine oil clean. A clogged filter restricts oil flow, causing premature engine wear. Replace your oil filter at every oil change for optimal engine protection.
Oil filter replacement intervals
Most manufacturers recommend replacing the oil filter with every oil change — typically every 10,000-15,000 miles or 12 months, whichever comes first.
- Always replace the filter when changing engine oil
- Use the correct filter thread size and gasket diameter for your engine
- Check if your car uses a cartridge (element) or spin-on filter
- Tighten hand-tight plus 3/4 turn — over-tightening makes next removal difficult
- Dispose of the old filter responsibly at a recycling centre
