•5wFor 25 km city use in bumper-to-bumper traffic and highway driving once in two months, maybe 200 to 300 km, I am confused between petrol and diesel. Petrol gives lower efficiency, but I am worried about the future of diesel cars and DPF maintenance. Please guide.

We would recommend that you look at a petrol car, as you are right to be worried about DPF issues with a diesel. All engines equipped with a DPF have to undergo a DPF regeneration cycle, and this typically happens automatically when exhaust temperatures rise high enough, basically when the car is driven for about 30 minutes at speeds of 60kph and above, typical a highway drive, which is not the case with you.
Thus, you would have to conduct a complete regeneration cycle when prompted, which typically involves a drive as described above or a stationary cycle with the engine idling above 2,000rpm for about 10 minutes.
