[Farmall] Synthetic oil in old machines

[E. John Puckett]

I have never tried it myself, but if it is on a new rebuild including 
all new seals in the engine it should be ok.  However if the seals , 
main and crank bearings, cam bearings, etc. are getting old or worn, you 
will have problems since the synthetic seems to be thinner.  That info 
is form discussion on some of the antiaue tractro forums, not my experience.
