You can use either a conventional or a synthetic oil filter with synthetic oil; however, for extended oil change intervals common with synthetic oil, a synthetic oil filter is generally recommended.
Understanding Oil Filters and Synthetic Oil
While both conventional and synthetic oil filters can technically be used with synthetic oil, the key lies in how long you plan to keep the oil in your engine. Synthetic oils are designed for extended drain intervals – often significantly longer than conventional oils. A conventional oil filter may not be designed to last as long as the synthetic oil, potentially leading to filter degradation and reduced filtration efficiency before your next scheduled oil change.
Conventional vs. Synthetic Oil Filters
Here's a breakdown:
-
Conventional Oil Filters: These are typically made with cellulose (paper) filter media. They are effective for standard oil change intervals (typically 3,000-5,000 miles). However, they may degrade and become less effective over extended periods, which is common when using synthetic oil.
-
Synthetic Oil Filters: These filters use synthetic materials in their construction, allowing for finer filtration and greater durability. They are specifically designed to last longer and maintain their filtration efficiency throughout extended oil change intervals associated with synthetic oil (often 7,500 miles or more). They also typically offer higher dirt-holding capacity.
Considerations for Choosing an Oil Filter with Synthetic Oil:
-
Oil Change Interval: If you adhere to shorter, more frequent oil change intervals similar to those used with conventional oil, a conventional oil filter can suffice. However, this defeats one of the main benefits of using synthetic oil.
-
Filter Lifespan: If you plan on taking advantage of the extended drain intervals that synthetic oil allows, a synthetic oil filter is highly recommended to ensure consistent filtration performance throughout the entire interval.
-
Vehicle Manufacturer Recommendations: Always consult your vehicle's owner's manual for specific recommendations on oil filter types and change intervals.
-
Driving Conditions: Severe driving conditions (e.g., stop-and-go traffic, towing, extreme temperatures) can put extra stress on both the oil and the filter, potentially shortening their lifespan. Consider using a synthetic oil filter in these cases even if you don't plan on extending your oil change interval to the maximum recommended mileage.
-
Filter Construction: Look for filters with robust construction, high-quality filter media, and features like anti-drainback valves (to prevent dry starts) and bypass valves (to ensure oil flow if the filter becomes clogged).
Summary:
While you can use a conventional oil filter with synthetic oil, choosing a synthetic oil filter is a better practice if you plan to use the extended oil change intervals that synthetic oil offers. It ensures adequate filtration and protects your engine throughout the entire service life of the synthetic oil. Always check your vehicle's manual for specific recommendations.
