The oil filter is one of the most important components in your engine's lubrication system — yet it's often overlooked or changed inconsistently. Here's what you need to know about oil filter service intervals.
The Simple Answer
Change your oil filter every time you change your oil. The two services are designed to go together. Putting clean oil through a dirty, clogged filter defeats the purpose of the oil change.
How Oil Filters Work
The oil filter removes contaminants — metal particles, combustion byproducts, and dirt — from the engine oil before it circulates through your engine. Over time, the filter media becomes saturated. A clogged filter forces oil through a bypass valve, sending unfiltered oil through the engine.
Oil Change Intervals by Vehicle Age
- Older vehicles (pre-2010) with conventional oil: Every 3,000–5,000 miles
- Modern vehicles with conventional oil: Every 5,000–7,500 miles
- Modern vehicles with full synthetic: Every 7,500–10,000 miles (some up to 15,000 miles with OEM filter)
Extended Drain Intervals
If your vehicle uses an extended synthetic oil change interval (10,000–15,000 miles), use a high-quality OEM or premium filter designed for extended service. ACDelco and Motorcraft filters are engineered for their respective brands' extended drain intervals.
The Bottom Line
Never reuse an oil filter. Always replace it at every oil change. It's a $5–15 part that protects a multi-thousand-dollar engine.
