Modern Vespa

I have used the Agip 75-90 syn oil as recommended on my first service of the rear hub. I don't have enough left for another service. ( used some on another service/ Vespa). But I do have full unopened litre of Amsoil syn severe gear 75-90 and Redline syn gear oil. Anyone out there used these gear oils in stead of the Agip ? ? Any clutch chatter? This scooter is amazing, and the wet clutch is superb. I'm aware I could just buy another litre of Agip syn 75-90, but I no longer have anything to use other these gear oils in. Thanks in advance for any replies.

Ok, I gave up the search. The Amsoil would probably be fine but don't want to take a chance. I ordered a litre of Agip ENI 75-90 like the OEM intended. Eventually I'll use the other gear oils I have collected, I just don't know where. Not sure I'll be buying any more scooters. Maybe I'll just put an add on EBay for the various new qts/litres of engine oil and gear oils I have. Also oil filters for various scooters and MCs.
