I'm trying to source hydraulic/transmission fluid for my 2015 HST. In the Transmission & Hydraulic Lubrication section of the owner's manual, it simply states STOU oil. In the Lubrication Table elsewhere in the manual, it lists 6 different kinds of fluid for the transmission: Citgo Transgard, Chevron 1000 THF, Texaco TDH and others.
I'm curious what people are using as I can't locate any fluid locally that specifically refers to the STOU spec.
