Every car is different, but most require an oil filter change between every 3,000 and 6,000 miles. Newer models tend to fall into the 6,000 miles + category. Meanwhile, older vehicles are likely to require more frequent oil filter changes. Your vehicle handbook will give you an accurate time-frame based on your make and model.
However, there are many factors that affect how often you should be changing your oil filter. These span from driving style to average mileage to general weather conditions. Your driving style may involve lots of acceleration and heavy braking. Most of your routes may be through towns. You may have a particularly high mileage. If any of these apply to you, you’re likely to require an oil filter replacement more often than the average driver.
It’s important to change your engine oil at the same time as your filter. This is because once the filter medium is completely saturated with oil and cannot hold any more contaminants, the oil begins to bypass the filter when it circulates. This runs the risk of contaminated oil entering the engine and causing damage.
