Re: what kind of oil do I use in a 1951 Packard 300

I recommend Classic Car Motor Oil. It is a multi-viscosity 15W40. It is a specially formulated with 1600 ppm ZDDP. The API service category is SH, SJ, SL. It is for older flat tappet engines for which the new oils are not compatiable. It is sold through the Indiana Region of the Classic Car Club of America. To order phone: 317-225-0040 or go to www.classiccarmotoroil.com. I am using it in my 1937 Six and 1947 Custom Clipper.
