i'm trying to figure out what substitute fluids I can use in a worse case scenario of running out of spare fluid on the trail. i've heard of using atf for power steering fluid, and i've heard of using water in place of brake fluid if you tear a line and loose all of yours, but what other tricks are there? i guess you can use motor oil in the difs if you had too, right? anything i'm forgetting? anything that you have found to work? thanks!
