Dear bro kindly explain This Graph as i am unable to understand as both 20/50 and 15/40 is marked under 40c
As per my perceprion, the graph shows that 20w-50 could be used between 0 to above 40c. and for the areas where temeperature level is between -5 and above 40c there it is recommending 15w-40.
What would you recommend for new bike AHL oil, KIxx 4t, ZIC M5 or Shell advance ax5 15-40?? Kindly share your experience
