I ride a 2014 (50cc) Tao Tao atm50a1
I Usually Run
Mobil-1 Full-Synthetic 10w-40 (4T) Oil.
But I'm Thinking about Switching to Castrol;
Because they JUST came out with an 5w-40 (4T) Oil
Since I do Live in Michigan and I do ride in the winter
I'm Planning on maybe running that and doing
Winter = Castrol 5w-40 (4T) Oil
Summer = Castrol 10w-40 (4T) Oil
*Has This Might Provide me MUCH easier winter starting.
LASTLY; FULL-Synthetic is the
ONLY Thing I Run in "Air-Cooled" Engines!
