1957 Thunderbird with a 312 engine should generally maintain oil pressure between 25 and 65 PSI. This range can vary depending on factors like engine temperature and speed.

I use Valvoline VR1 racing oil. It has a high zinc content. It can be purchased online direct from Valvoline for a good price.

It should be at least 10#s per 1000rpms when hot.
