Gearbox Oil

[Skeete]

What is the best oil for .

1) A tubby gearbox with LSD

2) A tubby gearbox without LSD

3) for the 3sgte

I would like a solid recommendation of the best gearbox oil for a 2 with an LSD. I dont care about cost, I just want the best, and are there any additives that can boost any oil's performance. I just have this nagging feeling that the gearbox oil has never been changed from new. 22000 miles in 13 years, chances are slim.

MT-90 MANUAL TRANSMISSION LUBE

Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that’s slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

Would you all recommend the same for an N/A with wear on 1st and 2nd?

I hear scuttlebutt on a more viscous oil sometimes working wonders for worn boxes.
