I am sorry but do Guzzis run with Agip oil only ? LOL !
Agip is a sh**y oil company owned in part by the Italian " State" ( government ) , it does not have anything special.... it's just oil .
Do yourself a favor , save time and money.
Tell you what,in Italy NO ONE and i mean it , NO ONE buy Agip oil, no matter if they ride guzzi, ducati ,aprilia ...you name it.
