You should change your oil filter every time you change your oil. While some sources suggest it's possible to change it every other oil change, this depends heavily on driving conditions and is generally not recommended. Replacing the filter with each oil change ensures optimal engine performance and longevity.
Why Change the Oil Filter Every Time?
The oil filter is crucial for keeping your engine clean. It traps contaminants like dirt, debris, and metal particles that can damage engine components. Failing to replace the filter regularly allows these contaminants to accumulate, potentially leading to engine wear and reduced efficiency.
- Clean Oil: A new filter ensures your fresh oil remains clean, maximizing its lubricating properties.
- Engine Protection: Consistent filter changes protect against harmful contaminants that can cause premature engine failure.
- Extended Engine Life: Regular filter replacements contribute to a longer engine lifespan.
Many sources strongly advise against extending filter life beyond a single oil change. While some high-mileage or extended-life filters may claim longer intervals, the consensus among mechanics and automotive experts is to replace the filter at every oil change.
Frequency of Oil Changes and Filter Replacements
The frequency of oil changes, and therefore oil filter replacements, varies based on several factors, including:
- Vehicle Type: Consult your owner's manual for manufacturer recommendations.
- Driving Conditions: Frequent short trips or harsh driving conditions may require more frequent changes.
- Oil Type: Some synthetic oils may allow for longer intervals, but check your owner's manual for specific recommendations.
Generally, most newer vehicles can go 6,000 to 7,500 miles between oil changes (the older 3,000-mile recommendation is often outdated). However, always prioritize the manufacturer's suggested interval found in your vehicle's owner's manual. Remember to replace the oil filter with every oil change.
Ignoring this could lead to:
- Reduced engine performance: Dirty oil and a clogged filter hinder lubrication and engine efficiency.
- Premature engine wear: Contaminants can damage internal components, leading to expensive repairs.
- Check Engine Light: A clogged filter may trigger the Check Engine light.
In Conclusion
Always replace your oil filter with each oil change. This simple step significantly contributes to maintaining optimal engine health, performance, and longevity.
