Some tips for getting good mileage:
- 155-65 tire profile, low rolling tires. I changed my car's tires with the same brand and same profile that comes from the factory.
- 33 tire pressure
- fuel from a good pump, preferably company operated
- oil 0-20
- smooth driving and no sudden acceleration/braking (I find the car gives best average between 65-75 in city drive
Like I said, this is a 4 grade verified car. A good car will be trouble free.
Most of the parts are the same as Pakistani WagonR though I'm sure body parts/lights will be expensive. I change air & oil filter at every oil change and get regular ones. This car is still on its original battery.
