We are talking tranny here, not engine. I run 15-40 in my engine and have had no problems. My advice on the transmission is, if you are going to run it most of the year in below 32F degree temps then go with 30 WT. If you are going to run it in above freezing temps most of the year then run 90 Wt. Hy-tran fluid is used in most tractors of the 70's and 80's and beyond. But with these old tractors, it is best to follow the rules or you will break something. 8N, 9N, and 2N Ford tractors were designed to run on 90 Wt oil. The hydraulics will fail if you try to run them on universal tractor fluid. I would assume that the Fordson hydraulics are similar. Dandy Dave!
