Hello to all a new member I found this website very interesting after three weeks of doing research I am out at about my wits end on the correct tractor fluid for this machine. This tractor is a 1956 machine The specs call for a MIL-1-2105 or straight mineral oil for the transmission. SAE 90. Upon doing further research this machine could very well have bronze or brass bushings in the transmission with that being said it looks like a non-zinc fluid is recommended. any recommendations would help on narrowing down the correct fluid for this old tractor. Also if I am in the wrong section for this question please let me know thanks.
Caterpillar d25u serial number17156
