Oil changes are one of the most frequent services you should perform on a modern car, but in most cases, that's still less often than we used to change these fluids. Many of us who started caring for cars decades ago still cling to habits we established when cars and oils were not nearly as well-made as they are today.
Conversely, as cars and oils have improved, some newer car owners may not give this critical maintenance the attention it deserves. It's easy to take the reliability of modern cars for granted, but that reliability depends on regular maintenance. So, let's take a look at oil changes and when to have them done. Cut to the chase: Always follow your car's owner's manual with respect to oil change intervals and the weight and composition of the oil to use.
