My general advice is that if you don't know the last time the oil pan was dropped and cleaned, then it's time to do it now before the next oil change. And while it's off, clean the valve tappet area and the crankcase breather and oil fill cap and the oil pump intake screen. After that there is no reason not to take advantage of modern detergent oils.
