Brumby gearbox oil change.

I'm about to drain and replace g/box oil on my 83 brumby.
Is it still best to use 80/90 oil, or is there a better alternative these days.
She's basicly just a street car, no real offroading.
Thanks

Use factory specification gearbox oil. How many kms is your Brumby? Is the gearbox in good working condition?

Should use one that's designed for transaxles. Hypoid cut gears such as in diffs have different lubrication requirements to the helical and straight cut gears in gearboxes, so a RWD manual gearbox oil is not suitable.
Castrol Multitrax goes alright; there's also a Penrite Transaxle, very expensive Redline and others.

Redline is something like $80 per litre?
I use multirax in mine at the moment - goes okay. (only crunches when gearbox is very hot)

She's done about 160,000. Gearbox is good, no crunching.
