Beware extra cost oil in a worn engine. Usually not worth it. I have never
been a big fan of Pennsylvania oils. One of the best I ever found for older
engines was Texaco's Havoline straight 30 weight oil. Once you wear to a
certain point multigrade oils don't work as well.
However - what I have found through LONG experience is that if you start
with a NEW engine - you'll find it will do best with Mobil One synthetic.
All synthetics are good, but Mobil seems best to almost eliminate engine
wear.
