The subject of fuels is my favorite thing.We had this topic recently on this or the Farmall board.First,TEL was added to Increase the octane rating,Not retard or decrease it,this allowed for higher compression(more power).Second,hardened valve seats and valve faces were necessary with the use of TEL,the TEL burned holes in the exhaust pipes and valve seats making the use of tougher alloys necessary at that time (1922-1923).Third,I've never heard of "micro-welding",the knocks and pings were from pre-ignition causing a sharp metallic rapping.This premature combustion was caused by the explosive qaulities of the fuel,what would later be called "Octane".The TEL raised the Octane decreasing or eliminating the knock.These old slow turning engines are fine with todays fuel,the tractor engines were designed to burn 70-76 octane,so 87 octane should provide plenty of anti-knock capability,you can even run Kerosene if they are equipped with the correct manifold,and there is no TEL in that,never has been.The tractor fuel of yesteryear was a very low grade distillate that Never contained any additive and it never harmed valves seats.Use 87 Octane gas and Detergent motor oil,use Synthetic oil in the winter,it reduces cranking effort and flows immediateley.If the technology is there,why not use it?That's why it was developed in the first place.BillJ
