My usual fuel choice us E-10 89, and the only E-free I've used is 89. That being said, I've not been able to notice a difference in the car's performance when sipping on E-free. That coupled with the car being new enough that it's designed for ethanol fuel, and if I'm going to spend alittle extra for better fuel I'll opt for E-91 or 93 rather than a lower octane E-free. JM2CW
