I have switched to Total 0w-20.
Reduced engine noise, less morning starting noise, acceleration feels better. Fuel avg 14.7, 14.8 in mostly congested patches.
At idling very less engine noise as I took out the car out of petrol pump. In running feels a bit different (as with all oils when you change them and drive out). Just drove four five kms from pump and now parked in office.
Got it from Total F-6 pump for 4,172 rupees and it had a card for 400 rupees free petrol, so it cost me 3,772 rupees.
Yes this grade is not available in drums so far.
Oil filter: I had my own OEM from the carton a friend sent from US.
