Bro I have just switched to below Oil and I got fabulous results
Havoline® Pro DS™ Fully Synthetic LE SAE 5W-40

This is imported Oil and does meet ILSAC GF 5 Standards.......
Previously I was using Total 5w-30 Future Series Fully synthetic but I found very good results of Havoline.
Mileage of my car is 68000........ Mine car average is 11-12 in city and 14-15 on Highway/Motorway....
