What are you to do if your service engine light is on you purchased it about week ago It has 75 thousand miles on it?
Er....Get the engine serviced?
A service engine light is not the same as a check engine light. In most instances the service engine light means you are in need of an oil/filter change. Refer to your owners manual to see what is needed at the mileage you are at on your vehicle. If you are talking about the check engine light then take the vehicle to a professional for repair.
