I think I'm at a point where I decided for myself to use an OAT based product (Peak) because it is hard or close to impossible to find the Piaggio-recommended Agip or Fina product with CUNA NC 956-16 specs in the USA.
To see how new Vespas are delivered from the dealer, I'd like to know what color is in your expansion tank (behind the right knee pad). You can see it when you remove the black top cap (CAUTION: don't remove it when the coolant is hot, or at least be very careful and do it s l o w l y !)
With enough ambient light, you will be able to see the color.
Please only look for it if your scooter is below two years old and never needed any work on the cooling system.
Who knows whether the scooters are even shipped with coolant in them, or whether the dealer has to add it at PDI?
