Dear sir, I have been watching your Deep Drive podcast every Saturday. It is always very informative, and the timing of your recent episode couldn't have been better. I am planning to buy a Toyota Camry in the next 2-3 months. As we know, the Camry is currently tuned for E20 fuel, but if the government introduces E25 or E27, it may not perform as intended. Should I wait for a few more months before buying it and see if Toyota introduces an E25/E27-compliant version? Your suggestion would be much appreciated.
Thank you for watching the Deep Drive podcast so regularly. Your concern about buying an E20 compliant car today, with the possibility of E25 or E27 becoming the base fuel, is understandable as there is a lot of noise of its ill effects on social media.
Our view is that you should go ahead with your purchase and not worry too much about a higher ethanol blend in the near term. A move to E25 or beyond cannot happen overnight. Before any such decision, the impact of higher ethanol blends on vehicles not certified for them has to be evaluated and validated by a government notified agency like ARAI. This takes time and involves testing a wide range of existing cars, not just new models.
While the government is pushing hard to increase the ethanol percentage in fuel, there is likely to be strong pushback from the auto industry because a sudden jump to E25 and beyond would affect millions of older vehicles on the road. Any technical assessment from agencies like ARAI is also likely to highlight the risks of moving too fast.
Even if a higher blend is eventually mandated, it will most likely be in the E25 to E27 band. Modern cars like the Toyota Camry are engineered with a reasonable buffer in materials and component specifications, so they can tolerate slightly higher blends than what is officially certified.
So, for your planned purchase in the next few months, you can confidently buy the Camry Hybrid now. Just stick to reputed fuel stations and ensure you use the recommended E20 fuel as far as possible.
