Re: What oil do you use in your V8 Packard?

Multi-weight motor oils were just coming into use when your car was made. If I recall correctly, Havoline 10W-30 was on the market and undoubtedly used. If you're worried about the ZDDP content of whatever you're using, order some ZDDP-Plus and add 4 oz. when you change the oil. Use weight/viscosity that was recommended by Packard for the average temperatures encountered where you live. You can use the diesel motor oil if you choose. Many do.
