How many miles should an oil change last?
Let us simplify it for you. Conservative estimates for oil-change intervals used to be as low as 3000 miles, before significant improvements in fuel-delivery systems, engine materials, manufacturing methods, and oil chemistry. Today, modern engines driven normally stretch intervals to 7500 or even more than 10,000 miles.
