People 250 / Re: How often do you change the oil with synthetic?
« on: May 09, 2015, 07:33:08 PM »
Hey guys,
First post here, and just bought my first scooter (2007 Kymco People 250) today, but I'll post more about that topic somewhere more appropriate...
So far as filtering and reusing oil, probably false economy. I think most experts will tell you it's the additives (think polymer chains) that break down with time/temperature, and it's the additives that need to be replaced.
I read it on the internet, but ASTM is a pretty good source:

(Hope the link works).
