In reality, none of this is relevant in well formulated motor oils since seal effects are measured and controlled in the formulating process.
Personally, I would avoid any oil that claims to be based entirely on esters or PAOs unless I knew the complete formulation and how the formulator dealt with seal balance.

Excellent!! There are SO many posters on BITOG who think Redline is 100% ester and others who think other oils are 100% PAO. I've been repeating this for years, but the "myth" seems to persist. (Not like it hasn't been fueled by the oil blenders as well!!!)
