Another query if I may? It’s definitely a Model T and according to MERL (very helpful) it was manufactured in 1947. The ‘working Instructions’ for the Model ‘T’ that I have suggest Castrol XL for the engine and machine lubrication and “In countries where it is impossible to obtain Castrol XL, any oil complying to specification S.A.E 50 may be used”.
Castrol XL appears to be SAE 30, so is SAE 30 or SAE 50 the correct oil to use in both, or doesn’t it matter? As the scythe and I are both of the same age, I would quite like to ensure that I do it no damage!
