Bear in mind that engine oil and transmission fluid also become darker after a while, so a deeper shade of red doesn't mean the power-steering fluid is bad. Before you jump at paying for this service, see what your owner's manual or maintenance schedule says. You probably won't find mention of changing the fluid. You should check the power-steering fluid reservoir monthly to make sure it has the proper amount and that the power-steering system isn't leaking. Reservoirs on many vehicles are the see-through plastic type, so you don't even have to remove a cap to check the level. Consult your owner's manual for the location of the reservoir in the engine compartment for help. You also should check the manual for the type of power-steering fluid that is required.
