Hi Doug Mayer & 300's NAPA in Portland, Oregon has it. They do not recommend using the "Not Street Legal" in our 1957 300C as this mixture has no detergents in the oil. In 1965, we were using Valvoline 30W Non-Detergent oil in the 300C and we had a valve stick open, of course that was the oil to use in our 300's at that time. I pulled the engine and did a complete over haul---cam, lifters, bore and pistons etc. Later, we used Detergent Valvoline Racing oil 30W. We are still using the Racing oil 30W.

I believe it has the zinc in it that we need--which is why it is not street legal at least for catalytic cars. Before I began using it, there was a slight knock in the valve train. Since I've begun using it, the knock is only in my head. I get it at the NAPA in Belfast, Maine.
