Is it okay to buy a petrol car? When will E85 and E100 fuels be introduced?
Yes, buying a petrol car right now is perfectly fine. Every new petrol car sold in India today is E20-compliant, so you're already covered for the current fuel standard. E85 has been introduced, but availability is still extremely limited, only a handful of pumps stock it so far, and there's no immediate timeline for E100 to roll out at the retail level.
Here's the bit that matters more for you: E85 and E100 aren't things you need to worry about at all, since these higher blends are meant strictly for flex fuel vehicles, not regular E20 cars. What you should actually keep an eye on is whether the base fuel blend itself moves from E20 to E30 in the coming years. Even then, most manufacturers have already built in a buffer in their E20 compliant engines to handle slightly higher ethanol content without issues.
As for wear and tear, any accelerated degradation of fuel system components would play out gradually over a long period, and the parts involved (seals, gaskets, injectors) aren't particularly expensive to replace. So our advice is simple: ignore the social media noise about ethanol "destroying" engines overnight. That narrative is mostly clickbait dressed up as concern, designed to rack up views rather than inform anyone.
The realistic downside isn't engine damage, it's a dip in fuel efficiency as ethanol content rises, since ethanol carries less energy per litre than petrol. Expect mileage to drop marginally as blends increase, not your engine to fail.
Bottom line: buy the petrol car you want, run it on whatever pump fuel is available, and don't lose sleep over flex fuel blends that don't even apply to your vehicle.
