I'm a firm believer in MMO in the gas tank, use it in all of our old Fords. I never used it until I stuck a valve in the Flathead, and MMO brought it back plus the engine ran a lot smoother. Today's gasolines are very dry, they don't lubricate like gasoline did years ago.

Good stuff. Also Kendall GT-1 20W50. It has ZDDP if that is your concern, otherwise you can buy a bottle of ZDDP from any old car parts supplier and dump it in with your favorite motor oil at oil change time.

Two older guys that had a real old Skelly service station next door to me as I was growing up, and these guys were mechanics from the 1920's thru 1970 when they retired, at this same service station that had old pumps out front, SWORE by Pyroil gas and oil additives. They used it in all of their customer's cars I think the yellow can (they were about the size of a tomato juice can) was for motor oil and the green can was for the gas tank.

I haven't seen that stuff for at least 50 years I think it came out of Wisconsin.
