Yeah sure until they "decree" it safe for all other years then they will force that on us too. Kiss 50mpg goodbye if that happens :-) (I am being sarcastic I don't know how much an effect another 5% will have but it can't be good)
I am curious about your 3% how much of the FILL was E10 and E0? half a tank of E10 and half a tank of E0 means you were not running E10 but running E5
and that assumes it was E10 that was pumped in. I have measured as low as E6 from regular gas stations.
Just curious. to get a good measure you need to run several tanks of each so that last tank is almost pure E0 or E10
