So, got oil changed with Honda 0w20 at 4300 kms as the 3 months period had elapsed. The dealership guy said that change with 5w30. I asked why, he said "sab yehi daltay hain". I asked how about 0w20. He said, "vo bhi theek hai, waisay vo hota turbo ke liye hai". In short they were clueless.
The difference I felt was increased in pickup. Car felt very light. Within the city my car never went above 8 km/l. After this oil change i m getting 9.5 km/l. But didnt notice any significant change on the highway.
Rest, on scheduled 5000k maitenance they checked nut bolts by lifting the car up. Cleaned cabin and engine air filters. Topped up battery water with nestle mineral water
and we are done.
