Use Toyota Motor oil 5w30 grade.
No need for fancy oils.
Go for what's recommended. That's enough.

Where, in KHI, is it possible to get Toyota Prius brake fluid flushed and replaced.
Proper equipment along with skill and knowledge is needed to bleed the brakes which I doubt anyone over here provides such kind of service.
I remember you did a brake service of merc, a while ago mentioning the tools and each and every tiny detail in it.
It was really informative.
Would be glad if any workshop could bleed the brakes properly.
