I run Rotella oil in my Mahindra 2015, and my 1996 Ford powerstroke diesel, and my yanmar Diesel generator, and my 2005 Peterbuilt with CAT power.
Rotella meets and exceeds all the requirements, and I've run nothing but in the above vehicles, and never had an issue at all that was oil related.
Not sure what to tell you about the HST fluid though. I never owned one.
