I am planning to buy kia seltos in some time before the end of this year. With this Ethanol controversy going on, should I buy the petrol variant or go for the diesel variant of Seltos?
Buy the Seltos petrol. Kia’s current petrol engines are E20-ready, so the ethanol noise should not worry you, and the real-world hit is usually a small drop in mileage, not reliability. For mostly city use, the petrol is smoother, quieter and simpler to live with, and you avoid diesel’s soot filter quirks that show up on short trips. You also save on the higher upfront price of the diesel and sidestep longer-term policy risk around diesels in big cities.
Go diesel only if your running is high and largely highway. The diesel will give you noticeably better mileage and relaxed cruising, so if you do something like 1,200-1,500 km a month at steady speeds, the maths can work in its favour. Just keep in mind it needs occasional longer drives to keep the DPF happy.
If you are buying before year-end and plan regular mixed city use, the petrol Seltos is the safer, easier choice. The only real trade-off is fuel cost on long trips, where the diesel will sip less.
