Euro S gear oil

Euro S gear oil
I did a search and now I am more confused. I am going to change the fluids on my LSD equipped 5spd trans. Any good reccommendations? Mobil 1 syn? Do I need additives?

I have an open diff and put Redline in. When i changed the gear oil in my BMW, I also put in Redline instead of Castrol. However, gearchange with both cars now is very bad, especially when cold. The BMW sometimes just doesn't want to shift back from 3 to 2 when it's a cold winter's day (0 degrees Celcius and below). I'm gonna change both cars to Castrol full synthetic which is not only a lot better in my opinion, but also cheaper and more easy optainable!
I guess not everyboy agrees with me on this, but it's just my own experience.

I have a frankenblend in mine, for some reason I thought the gearbox only held 3 qts, so I I got 3 qts of the Redline NS 75-90, and it did not fill it, so the search was on for what we had in the shop, ended up with a qt of Mobil one 80-90 sys, 2 bottles of BG gear oil additive and a half a qt of straight mineral 90.
Yea, that needs to be changed, but it shifts ok, bit stiff when cold.
Seems the general thought is to use just the Redline 75-90 NS.

On FerrariChat, gear-lube is a big topic. Rifledriver is a well known guru in the F-car world.

Ferrari specs GL5 gear oils for the transmissions. Due to Ferraris specs Redline will not officially suggest anything other than GL5 gear oils.
GL5 basically means an oil that is designed for medium to high offset hypoid differentials. MTL is a GL4 lubricant which means it is designed for medium to low offset hypoid gears. In the 308, 328, 348, 355 transaxles there are NO hypoid gears of any type, hi, low, or medium, offset.
I am not ordinarily an experimenter with others cars except in circumstances where the official way is obviously not working but I have seen MTL used with great success and zero problems in 308 transmissions since the product was introduced many years ago. It was also the oil of choice in the transaxles of the 355 and 348 Challenge race cars with zero problems. Those transmissions were subjected to greater stresses and heat in one weekend than most of our transmissions are in a lifetime. I cannot say that however of the AGIP oil spec'd by Ferrari at the time. One session at the track finished off several transaxles and we were told unofficially by Ferrari to quit using it in cars that would see track service. That garbage did remain the official oil.
I have been using MTL in customer cars that had cronic shifting complaints for several years including one 85 308 in daily service with over 115,000 miles on it and the owner is pleased to this day how his transmission performs.
It's great oil. If you have a shifting problem use it.
I would not use it in any transaxle in a 275, 330, 365, BB, BBi, TR, 288, F40, 550, 456, 360, 430, 612, or 599. Those are all medium offset hypoid gear differentials and should have GL5 oil."

At the shop as a practice we use The 75-90NS because it is compatible with all the gearboxes we service but when there is a complaint of hard shifting in the cars without hypoid gears (308,328,348,355) we use Redline MTL. It was a favorite with many of the Challenge teams and makes the cars shift unbelieveably easy.
