well autobarn had a opening sale and well i bought some HD 50w oil. it only has the single weight on it. I was told that in our climiate it does not matter so much about the (w)inter weight link is below also my engine is a 184cc pitster pro engine. For run in he reccomended 30min light use with this oil, then dump then same at 4 hrs then i should be good to go.

This sound right
