Does Ethanol Increase Fuel Consumption? Comparing "E10" against Shell V-Power ⛽ E10 E6 🆚️ E5 E0 mpg

In addition to what I mention in the video, the car is doing the same commute to keep the elevation and test cycles consistent. The Fiesta was run at higher than recommended tyre pressures, 35PSI on the front and 32PSI on the rear Goodyear Eagle F1s. My two tanks were basically my normal driving and where I attempt do drive as economically as possible, something I'm not particularly good at, while on my normal commute--even then, if I have overtaking opportunities or am running late, I did have to forego the economy. In any case this was also consistent with both fuel types. The only major difference was the weather, although the average temperatures weren't radically different, while testing the Texaco E10 (6%) we had two very hot days reaching 39 degrees celcius, while the V-Power we had more hot days overall, but at 32-34 degrees. I don't think this would have majorly affected results, other than my using the aircon, which I did want to avoid, but ended up using it for longer on the V-Power, which showed to be the more economical fuel.
