About this episode

The episode discusses the implications of increasing ethanol in gasoline and its effects on engine performance and fuel economy.

With increasing gas prices, is flex fuel the way to go? I talk with mechanic and automotive tuner Brian Conrad about tuning engines for E85, ethanol fuel blends, and why more ethanol is being mixed into gasoline at the pump. This isn’t just about project cars. Ethanol fuel impacts daily drivers, fuel economy, and performance across many modern vehicles. We also discuss standalone ECUs, engine tuning, performance mods, flex fuel systems, and the real-world pros and cons of running E85. Whether you enjoy wrenching on cars, optimizing performance, or just want to understand what’s going into your fuel tank, this episode explains how ethanol affects horsepower, efficiency, and engine tuning.Get your GPS tracker now and protect your car!
