What do I really need besides an oI’ll change each year. Every other year I take it to the dealership to get it checked over, oil change, differential fluid changed and joints lubricated. But even if I take it back just for an oil change to the dealership, they charge an arm and a leg just to do that. I am looking to do that myself and I just was wondering if there is anything else that needs to be checked on an annual basis. I drive about 250 miles per year.
