Farmall M fuel

Chris Have only had this antique tractor for about 2 wks and am wondering what about unleaded fuel and lead additives. Is that really necessary or will it burn my valve seats any ideas?
John M Forget the additive, you dont need it. Unless your working the snot out of it constantly you wont hurt anything.
jim John is exactly right, IH recommended no-lead gasoline in their tractors way back in the 60's and said it was fine for any and all older models that had hard seats installed in the exhaust valves. If you did not have hard seats like some of the very early model m's , h's etc(which almost all have had seats installed since then)you may need to readjust the valves more often if working it hard. Lead served the purpose of lubricating the valve face as it slides back down on it's seat every time it closes and has no noticable effect on valve guides as the engine lubricant handles that. Of course, lead primarily was used to establish the octane number of the fuel so they have to use other additives to establish that in a non-leaded fuel.
