Re: Can synthetic fluids be used in Packards?

I tried various oil blends and 30-wt in my Clipper over the years and have eventually settled for 15-40 and my car seems to run great with no knocking, smoking, and very little leakage. Since I generally put 1,000 to 1,500 miles a year on the Clipper, I change my oil twice a year and the filter once a year. The viscosity never has a chance to wear down. And since I change my oil as often as I do, I figure I might as well use good conventional oil rather than synthetic, which is a lot more expensive.
