Re: IML: Anybody have a '64-'66 Owners manual?

["Rob P" <fristpenny@xxxxxxxxxxx>]

What do you have against 10W30?  Most of the temp charts still recommend it 
for the same temp range as 10W40.  20W50 will probably give you a hit in 
mpg.  I've never used any more than 10W40 in my '70 440 and (knock wood) the 
oil pressure is still good.
