I've been able to get the Shell Donax TD. It works well at 0'F to Summer temps. Here are a few others Suggested from Kioti. You want to stay with a 10W-30 multi-weight for best performance. Shell Donax TD, Texaco TDH oil, Exxon Hydraul 560, Exxon Torque Fluid 56, Pennzoil Hydra Tranz, Mobilefluid 424, BP TracTran UTH, Citgo Mystik JT-5 Universal. I don't know the weight of all trac or high guard. As mentioned, it has to be trans/diff/wet brake/common sump rated.
