Re: Which Engine Oil?

When I got my Packard it had only been operated rarely in almost 50 years. The second owner who bought the car in 1955 apparently never once drove it in over 20 years. When After dropping the oil pan (always a good idea on an old engine!) and cleaning out the heavy sludge I found there, the engine also had a serious main seal leak. After switching to Rotella 15/40 I have noticed that the seal has almost entirely stopped leaking. I attribute this more to the fact that the car is now being driven much more than in many years. There are no other seals leaks in the engine in the time I have used Rotella.
