Cars overheating these days? Yes and ethanol-blended fuel is one of the reasons, let me explain. After doing some research and speaking with experienced mechanics, it’s clear that ethanol does impact engine behavior especially in smaller engines (1.5–2.5L). Here’s the simple breakdown: Ethanol has lower energy per litre compared to petrol. So, to produce the same power, the engine has to inject more fuel and work harder. That naturally increases overall load and heat generation. Now imagine real-world Indian conditions stuck at a red light, AC running, temperatures above 40°C. That’s where the stress adds up. This is something both the government and the common user often overlook. The tricky part? You won’t easily notice slight overheating. It’s gradual, silent damage that keeps affecting engine health over time and reduces its lifespan. Honestly, the way things are going, cars may not last as long as they used to. That old reliability of running vehicles for 10–15 years feels uncertain now 4–5 years might become the new normal if this continues. Not trying to argue just observe it yourself, research a bit, and you’ll start connecting the dots! 😉
