The mechanic explains

Influencers who once warned you about E20 are now pushing fuel additives that supposedly "cancel" ethanol and double your mileage. Sounds too good to be true? That’s because it is. In this no-BS breakdown, we expose the hype, explain what fuel additives really do (and don't do), and help you separate fact from marketing nonsense with real-world tuning insights from the garage.

Everyone’s panicking that E20 fuel will kill cars, corrosion, rust, hydrolock, cold starts, you name it. The truth? BS4 = Euro 4, which means all BS4 cars are already ethanol-ready. This blog breaks down the hygroscopic effect, water tolerance, and real-world risks with facts, math, and a little sarcasm, not influencer fear-mongering.

Despite the fear-mongering around E20 fuel, modern BS4+ cars are built with advanced sensors, ECUs, and safety systems to keep engines safe. Here’s why E20 isn’t the engine killer it’s made out to be and how your car constantly corrects, protects, and warns you before damage happens

E20 fuel isn’t going to blow up your engine, and tuning, when done right won’t ruin your car’s reliability. At ICD Tuning, we’ve seen firsthand how much headroom manufacturers build into their engines. With proper maintenance and smart upgrades, even older cars can adapt to change. This blog explains engineering tolerances, busts myths, and shows why panic is pointless, it’s not the power that kills cars, it’s neglect.
