Yaar nai engine kay kiae 20w40,,ya 10w40 oil kafi hai aur khaas tor par 70cc kay liae..MY cd-100s response got better on Atlas Honda oil being less viscous at extreme temperatures,,magar bike thori zyada garam hot hai..
Pehli baat yeh hai kay Caltex 20w50 oil motor oil hai gariyon kay liae ni.
Caltex 4T 20w40 istamall kar saktay ho..
Castrol activ 4T 20w40(better than havoline 4T)
Zic 4t 10w40 (semi synthetic)
Aur bat rahi kay whether Honda oil is ok or not..Honda bikes kay warranty period main claim karnay kay liae Honda oil lazmi hai..Matlab pehlay 15000 Kms tak warna wo claim kisi kisam ka qabool nai kartay..Koi waja to hai na phir?It has quality but if you want the best you will have to invest double the amount and go with LiquiMoly 4t
