Dear Dr Stupid,
I am tapping your vast knowlage,
Is it possiable for Oil,
In a 125cc to become thick and dirty after less than 500 miles.
I recently had the oil in the 125cc changed,
I checked the oil, It was thick and sludgy,
So i changed it,
I think oil should last more then 500 miles,
Dont you ?
Love Mom.
