I also have multiple brands and have done considerable research and have settled on 2 brands that meet all the usual specs. Last change and have bought for next time. Chevron 1000 THF
Also, Mobil Mobilfluid 424
Both are very good,use the Chevron because it is orange and you can spot any leaks.
Chevron 1000 THF meets Agco 821XL, John Deere J20C, Ford New Holland, ESN-M2C134-D and FNHA2 C0201, Massey Ferguson M1135 M1141 M1143, White Q-1826, Case JIC 143 145 MS1206 1207 1209 MS 1210 TCH, Oliver Q-1705, Minn-Moline Q-1766 1722 1766B,Catepillar TO-2, Renk Doromat 874A 874B, Kubota UDT, International Harvester 86, Volvo WB 101
Flash Point o degree F 455, Pout Point -44, Viscosity Index 145.
Just paid 73.50 per 5 gallon bucket. Could get off brand cheaper, but will not risk Hydrostatic trans, wet brakes, IPTO etc.
