Which Engine Oil?

Posted by Boro On 2007/10/3 9:30:10

Hi all,
I know this subject has probably been covered and don't want to waste a lot of time on it. But, I've done a search and can't seem to find anything that will help me make a decision on which engine oil to use in my 52 Packard 300.I am a fairly new Packard owner.
I have purchased Rotella T 15w-40 and was going to change the oil here pretty soon, when someone recommended using Castrol 20w-50 with an oil additive.

Any help/suggestions appreciated.
