Thanks for the reply as I m willing to try this oli over zic so that's why asked about this thing. But in my experience even when my bike is new and done the second oli change oli was LM and it came quite dirty as well that doesn't mean it is a bad oli. So that's why I got confused. Khair will switch to Valvoline soon.
And do u ever experienced decline in top speed after u switch to 20-50 from 20-40.
