For HH Hunk recommended engine oil 10W-30.

The number before the 'W' is the 'cold' viscosity rating of the oil, and the number after the 'W' is the 'hot' viscosity rating.

Lower the viscosity rating, thinner the oil and higher the viscosity rating, thicker the oil.

Most engine wear occurs immediately after a cold start. Lower the 'cold' viscosity rating of the oil, thinner the oil as a result oils circulate easily at lower temperature for which engine start smoothly and reduce engine wear.

20W-40 That's men you are using higher cold viscosity rating oil or thicker oil than the recommended one. As a result, increase engine wear & reduces engine life.

Always strictly fallow the manufacturer recommended engine oil grade.

Hero Honda 10W-30 engine oil is good enough for all Hero Honda bike. In addition, price of the oil is chief compare to all other branded oil.

20/40is best because 10/30is thinner if it when heat by running than also will be some more thin so drive smoothness will less ...
russell try once 10/30 and another one time 20/40 which is best @ running u will feel and use that oil..

'Cold' viscosity rating ('W') is chosen under specific climatic condition. 'Hot' viscosity rating is chosen under maximum engine operating temperature condition.

Higher the viscosity rating, thicker the oil. Result poor oil circulation.
