Need Help on Fluid choice

Kind of a can of worms question, because there’s so many varied opinions.
I have to agree with the Lucas if you want a good quality product.

For what it’s worth, when I ran older manual transmissions I would customize the fluid mix depending on how the trans reacted.
Some work great with 85/90 and some worked better with 30wt, and then some even better with ATF.
It depended on how it shift
Thank you , makes sense. Car is street driven but power shifting happens from time to time.
