How Often to Get an Oil Change: According to Mileage
If you consult the owner’s manual, it’s like to say either every 3,000 miles (older vehicles, especially from before 2010) or every 5,000-7,500 miles (newer vehicles post-2010). This has some relation to the type of oil people use, with older cars using more conventional engine oil and newer ones using blends and synthetic oils more commonly, which allow for greater intervals.
Besides the two we just mentioned, two more common recommendations are every 1,000 miles, and every 10,000-15,000 miles.
