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

OK Guys,
My experience with oils in my 56 Executive in past 2 years I have owned car. First oil I ran was Castrol 10W/30, had loud lifter clatter on start-up after sitting awhile, especially overnight. Next oil used was Rotella 15W/40, some lifter clatter as above but not as bad. After reading the SDC article on motor oils and additives I ordered a case of Mobil Delvac MX 15W40 and did oil change. Just got back from a 300 mile trip and not as much as a whisper from the lifters at any length of down time. Just my observation from using different oils.

ps:As for the upgrade to disc brakes, the saved my a_ _ from plowing into an 18 wheeler blocking 1/2 I-30 in driving rain storm on the way home.
