I got my mehran at 6000 km. I changed the oil to shell 10w40, engine noise increased and i changed it after 2000 km as i was not satisfied. During the 2000 km period, I experimented with different fuels and found Total to be the very best. It gave me no knocking, good costumer service, and a decent fuel average. I used Total 10w40 in my Mehran and it changed everything significantly. Less engine noise and rattling, better sound, and a life span of 5000 km. I did the same in my motorcycle by buying Total oil from Hyperstar and gave my similar results. My corolla also had the same results,
I am completely satisfied with Total, and i would reccomend it to everyone.
