That’s good news... I guess, since we will probably all be forced to use this stuff sooner or later.
When local gas stations started selling E10, they didn’t post any notices that it was E10. We noticed that our cars didn’t seem to have the pep they did before. I thought there was something wrong with my Mazda 3. Once a law was passed requiring stations to reveal what kind of gas they were selling, we bought real gas only and noticed a big difference in the cars’ performance.
I’ve heard mileage reduction on E10, but not performance complaints. Often the performance tends to be a bit better.
E85 is often used for cheap racing fuel around here in Indiana where it is readily available.
