Re: gearbox oil

haynes manual says EP 80W/90, standard gearbox oil. i wouldn't use a modern sythetic as it may be too thin and cause leaks?

Re: gearbox oil

Redline I have it in my car makes some serious difference. It's pricey but worth it.

Re: gearbox oil

I use Redline Lightweight Shockproof when I can afford it. I have found that it gives a better gear change quality when cold and about 4 bhp extra on the dyno. I put it in my old Minari racer (Sud 1.2Ti box) in 1998 and it has been there ever since without problem.
My current car will get the same when I get round to it.

Just remembered that I also put it in my 156 Selespeed gearbox and it made a big improvement to that. Cost around £50 though.
