What viscosities of PAOs?
Just trying to figure out what I want to look for in my next MTF. Right now I like Redline MTL but I assume it is mostly esters and I'd like to try something with a bit better severe cold properties.
I am also considering Synchromax and Pentosin MTF2 but I think these are mainly PAO fluids. Just curious what differentiates their real world properties when it comes to the base.
but I don't want to get into specific fluids. I'd just like to know what are the pros and cons of each in MTF if there is such a thing. I thought I had read an article a while back trying to show conventional was the best fluid for an MTX but I don't remember why and I don't remember if it was looking at PAO or esters.
Most of the higher end synthetic MTFs contain a mix of GroupIII, IV, and V base oils.
The base oils mainly affect low temperature shifter drag and maintain a better fluid film at higher temperatures due to their inherent VI.
It is the additive package that will affect your synchro engagement.
I would concentrate on finding a dedicated MTF that has a viscosity close to your tranny spec, and it appears the Redline MTL or the Amsoil MTF is close.

If so, please expound on those pros and cons.
Your question was the only obtuse statement in this thread and it was answered above.
Your
assumptions about what base oils are used in the products mentioned are incorrect.
No SINGLE API base oil type is used in high-end, synthetic MTLs as you have assumed, marketing hype discounted.
Each base oil type presents its own advantage to the mix for an appropriate cost/benefits ratio.
Again, maybe you could possibly clarify your question.
I think that you should consider giving up on this my friend.
