check the archives in MARC for Roger Kauffman the Tech advisor for many years. He had a '30 pickup he ran for years, all over the US and used 100% STP in the steering box, transmission and rear end.
He opened them up after 50 k miles and the fluid was clear and everything was operating properly.
A pretty good real life testimonial in my view.
