Gearbox oil for Vespa 125 FL

Hi! I want to replace gearbox oil in my Vespa 125 FL. In the manual it says I have to use Agip SIC 75 Oil, which doesn't exist anymore and I can't find any references to it on the internet. Anybody knows what oil I have to use?

i've been using ipone 'box 2' synthesis gearbox oil on my 2T stellas. it's a conventional/synthetic oil blend. performance wise i haven't really noticed a difference, but the oil looks and feels better at oil change then when i was using conventional only SEA 30 oil.



SAE 30 oil. Any brand.
