Newly Reformulated Fuel
Now that we are getting ethenol laced fuel I'm curious as to affects on our vehichles. Do we need a retune?, more or less prone to detonation?. The alcohol will absorb water so what happens to octane rating. Tuners chime in please.

The most current information derived from controlled environmental testing is that on fuel injected vehicles, fuel mileage may decrease by approximately 2%.

In addition to worse mileage on E10 there is a negative side effect of about 5% leaner AF ratio. This may or may not be offset by the slight octane improvement gained. Check with your tuner to be sure.
