Good. The oil you changed is of 10W30 viscosity. Not 5W30. No issues it’s OK.
Now you are to use HOBC petrol only filled from Total Petrol Pump. I am not sure about Karachi, but find out a reputed Total Petrol Pump and only 100% HOBC is to be filled always.
How is the condition of your tires? I mean the tread condition? Go to a reputed wheel alignment and wheel balancing workshop and get your tires inspected.
If tires are OK, get wheel balancing and wheel alignment done.
Also, tell me the size of your tires currently installed. Read the tire side wall to check.
Drive the car for about 500 KM and also tell me how the drive feels now. Note the acceleration; is it very good or just OK or not Good. If confused, ask you friend to drive the car who has Vitz experience to judge the acceleration.
Bro, my name is Imran, so please address me as Imran.
