I am new and I have tried to make sense of what fluid to put in my 6 speed manual transmission.

Redline MTL would be one of the very best choices possible for your particular transmission. It's available on Amazon and Summit Racing among others. Don't bother looking for it locally.

I can't recommend Synchromesh from Pennzoil or GM, not many like how the transmission shifts after using it.

And a big welcome to JF!

I've used penzoil, GM and several others. I never noticed any improvements switching from one brand to another. You do know that syncromesh is just 5w30 oil without the additives.
