Synthtic oils are always better if the oil grade is recommended by your machine manufacturer - esmein liquin cool ya air cool ka koi chakar nhn hai - the only thing is some oils are not good for wet clutches which are in bikes - baki koi issue nhn hai. Liqui Moly 10W-40 Motorbike Synthetic hai yet its excellent for bikes with wet clutch. Check here LIQUI MOLY Pakistan-Motorbike 4T 10W-40 Street (1 Litre)
