2) Top speed has marginally increased by 5 kms
3) Acceleration is much much better, pulls great even in 4-5th gear
4) However engine does heat up more then before (No idea why)
5) But there is surely a drop in mileage from 38 kmpl to 33 kmpl (maybe this is due to my 2nd free service)

PS: I & my frnd (FZ-s owner) switched oil to castrol power1 simultaneously last month & gotta tell u that we both are much happier with it then we were with yamalube
