Choosing the right hydraulic oil can be very confusing. I need to change hydraulic oil in a 1967 Farmall 656 gear drive. I was thinking of using the Traveller Premium Universal Transmission/Hydraulic Fluid. The stuff in the black pail for $39.99. They also have the same thing only it's Renew for Older Tractors at $49.99, both in 5 gal pails. Local NAPA has a sale on Kendall Hyken 052 for $54.99. As you can see, big price difference. How does a person choose? Also would any of these oils be OK in a 1949 Allis Chalmers C
