TEL (tetra-ethyl lead) was first commercially used in gasoline in 1924. Any dual-fuel tractor does NOT need, and did NOT need lead. Kerosene never had it. in fact, I would go as far to say that the gasoline only tractors up through the 1950's (early) will run just fine on regular or mid-grade (87 or 89).
When your compression ratio starts getting around 7:1 or greater, then higher octane is an absolute requirement. BUT, it still does not have to be TEL. Your SC should be around 5.5:1 or there abouts. Regular gas will work just fine.
As far as the oil goes, clean oil, and regular oil changes as required is all you need.
any of the F-series or Letter series tractors are low compression, low RPM's. Clean oil and clean fuel is what they crave.
