@ruffdog it is the all purpose transmission/hydraulic/brake fluid. Mine is not hydro but I think you could use the same. The SAE ratings are different for gear oil vs motor oil... 80w gear is same viscosity as about 20 weight motor oil from what I've read. A lot of the tractor fluid makers rate them as 10w30 (all purpose tractor fluid).
