Thanks Joe, I'll take your word for it and I'm glad to hear that the oil I put in there contains no sulfer. Better safe than sorry. But how does one tell of oil contains sulfer or other friction reducing elements that might be inadviseable for use with O/D? It would sure be nice if you or someone who knows more about this subject compiled a list of oils that are best for our vintage cars.

II Jeff, Yes, the oils have gotten better and so have the parts they are designed to protect. Unfortunately the brass synchro rings in our cars are vintage 1960's and are damaged by sulfur additives in gear oil in spite of what your mechanic says. The Valvoline 50 wt oil you are using does not have sulfur additives so you will be ko. In fact I seem to recall that some of the literature that came out when our cars were new recommended using that sort of stuff in gearboxes.
