Just for clarification - I'm not an expert when it comes to 75W-80 GL-4 gear oil. I bought a gallon jug of Redline MTL at the time, because it was easy to obtain through Walmart & Amazon. The only other option I remember back then was Ravenol MTF-2 GL4 75W80, which was more expensive than the Redline at time. Other forum members were singing praises about the Redline, & I have no reason to believe it's not a good product.
Redline carries three levels of Shockproof gear oil (heavy, lightweight, & superlight). I don't know a thing about racing oils.
This discussion is sort of in the wrong thread, but that's nothing new here!
I do have a thread on the shockproof haha.

Ideally I think for this car you want the "superlight".
My mechanic can only order "lightweight" and "heavyweight" so I went with the "lightweight".
I think heavyweight is too thick.
Redline.com says:
Superlight
Film thickness greater than an SAE 75W90, yet low fluid friction like ATF
Lightweight
Film thickness greater than an SAE 75W140, yet low fluid friction like 80W gear oil or 30W motor oil
Heavy
Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90.

I apparently forgot about that thread. Personally, I wouldn't use racing gear oil in my Mirage, but that's me. It's not about the extra cost either.
I'm 61 years old, & all of my vehicles have been manuals. My 2017 Mirage has received more gear oil TLC (tender loving care) than any of my other vehicles, and I have never experienced a manual transmission issue in the past.

If the fluid fixed an issue you don't have, I guess it worked! ROTFLMAO
If a driver rushes the gear lever to change gears like formula one style instead of simply letting the gears plop in without forcing them, the brass synchro rings will wear out much quicker. Usually it begins with first gear not going in as smoothly as with a new car. Synchro rings are actually like little brakes that will force a shaft to rev at required speed to get chosen gears to mesh and hence change gear. Force the lever like some juveniles and you will wear them out real quick. That doesn't have to be. Not a sign of synchro ring wear on my 10 year old car.
Btw, mine has 75W80 GL4 fully synthetic (real synthetic!) gearbox oil from a local maker (ROWE) that makes a good portion of his business in the professional racing market.
The practically same gearbox is also in a few Toyota Aygo C1/107 and then it comes with 75W85 GL4 gearbox oil.
