Your engine oil should typically be changed every 5,000 to 7,500 miles or per your vehicle's manual, as over time it breaks down and gets contaminated with dirt and debris. That grimy oil can't lubricate moving parts effectively, leading to increased friction and heat, which speeds up engine wear and can cause costly damage down the road. If your oil looks dark and sludgy on the dipstick or you hear unusual engine noises, it's definitely time for a swap.
