Lol, these topics are always a can of worms. So many opinions and different experiences. Many will say x oil gave them 100’s of thousands of trouble free miles while others will say that x oil destroyed their tranny & tcase etc. Many won’t trust even the manufacturers recommendations these days and occasionally that’s for a good reason.
At the end of the day it will just be up to you because the suggestions will never end. I hate to say it but this is one of those topics that requires you do your own research instead of going strictly off of what your pears say. Otherwise this is about as subjective as health advice, in other words, everyone has an opinion and, of course, some great reason for believing their opinion.
