I don't have any personal experience on Glady
Please go through the first post of Engine oils thread for more details on the grade.A synthetic oil comprises of more homogenius atoms which makes the degradation less and lubrication better.If glady recommended grade is 20W40, you can go for Motul 7100 FS oil(720 rs) which is 20w40. But I believe 5100 should do good for you, its a wonderful oil
