I remember that my 1954 Ford sedan used 80W-90 gear oil in the steering box. Double ought grease might also work for that application. At our power generation facility, the Limitorque valve actuators used the 00 grease. Problem was, the units for the furnace soot blowers all leaked oil due to the very hot atmosphere. Operations people wrote numerous maintenance requests to repair them but nothing could be done. Oil from 00 grease comes out of suspension when around hot environments.
