What's the correct grade of oil for the GS gearbox? winter layup is about to happen, and busy making a 'to do' list.

It’s a 75W90 GL4. The book says Rotra LSX, which is available from Superformance and some Italian ebay sellers.

You can get Coma cheap from EuroSpares but I would not advise using it, causes diff chatter when cold - the LSD clutch plates don’t like it.

Buy Redline or Motul fully synth more expensive but quality and worth it.

3L.

Its 2.x so 3L required.

The oil will specify something like 300LS that signifies Limited Slip
