Should I buy petrol or diesel car? My budget is Rs. 10 lakh through the CSD route for long-term ownership. I currently own a 2022 Hyundai Creta Diesel, but my monthly running is relatively low. I am also concerned about future fuel regulations. If I buy an E20-compatible petrol car today, will it be able to handle higher ethanol blends that may be introduced in the coming years?
Given your low monthly running, we would recommend a petrol car over a diesel. The fuel-efficiency advantage of a diesel only starts to make strong financial sense when you're covering substantially higher distances. Since you're already driving a 2022 Creta Diesel, moving to a petrol for your next car would also help you avoid concerns around DPFs and future diesel regulations.
We also wouldn't let ethanol-blending concerns drive your purchase decision. While India could move towards E27 or even E30 fuel in the future, there is currently no official roadmap confirming this. Most modern E20-compliant petrol cars have been engineered with a margin of tolerance and should be able to handle somewhat higher ethanol blends without any immediate issues. At worst, some rubber components may wear slightly faster over many years, but these are typically inexpensive parts to replace. The bigger impact is likely to be a small reduction in fuel efficiency rather than any major reliability concern.
For a Rs.10 lakh CSD budget, we would suggest looking at the Hyundai Venue 1.0 Turbo Petrol or the Skoda Kylaq. The Venue's turbo-petrol engine feels punchy and refined, offers a premium cabin and is very well suited to everyday use. The Kylaq, meanwhile, feels more substantial, offers excellent safety credentials and has one of the most enjoyable turbo-petrol engine and automatic gearbox combinations in the segment.
