I live in florida, I've switched all my units to 15w40 C rated oil, except 1.
Since I've got so many tractors.. i don't get tons of hours on each one.. so i do yearly oil changes.
as for dino vs synthetic.. I run dino oil in all my diesel and gas tractors except 1, and in my trucks, i run valvoline 5w40 synthetic ultra blue C rated oil.
the 1 exception I keep mentioning is a 1963 ford 4000 gasser.. I just recently had to go thru the head and top end as I had stuck valves and bent pushrods.
I cleaned it up real good and got her back going.. but found tons of deposits on the intakes....
I went to a 10w30 S rated synthetic oil in that tractor to see what the detergent package does for her. the S rated syn oil was quite a bit cheaper thant he C rated syn oil... and for a gasser.. the S rated syn oil is more than fine.. way better than what was available in 63..
as for adds? I put a lil atf in my gas and oil, plus now use seafoam and stable in all my gassers after that weired fouling on the intakes in that tractor. think i may have had a bad batch of gas that turned and gummed her up perhaps..

Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
