Being a Dad, especially nowadays, is tough. It’s difficult to satisfy all the expectations of “all” the members of a family – sometimes it’s tough to keep only a “couple” happy thru the tough times.
But your “Dad” has fairly exercised his authority & for the most part, been a class act with the 6K+ members of this forum. Probably not too many sons/daughters hear that comment about their old man, until it’s too late to properly appreciate.
Give your Dad a call & say Hi. This simple act is more important than any comments regarding motor oils, will ever accomplish, on this forum!
