100% STP in the transmission and steering box is what Roger Kauffman, the MARC tech advisor ran for many years with great success. He drove his Model A's to all the meets, and wrote a big article for the MARC NEWS about a trip from Ohio to the West and back in his Tudor....I have to believe the STP worked well.
