NO, no, don't do that! So far most all Kymco scoots have a specific amount to put in each gearbox and it is ALWAYS way less than the fill hole. I, from experience with my first Kymco, filled to the fill hole. That Agility 50 had an immediate, massive oil leak! Juan brings a real point about Kymco manuals: many mistakes and conflicts. Here is a suggestion: Use .23 L and if you wind up with an oil mess, wash it off and use .18 L. Not trying to be a wiseguy, really! Maybe someone who has experience with this model will educate us all.
