I have started my own E85 experiment with a normally aspirated '90 Dodge Caravan 2.5 that I drive occasionally. I have used various blends and alternated with RUG to compare results. So far the mileage seems to be as good or better than I have been getting on regular unleaded. This latest tank fill was almost all E85 and the power is way down. It seemed fine on the highway but pulling a hill cold and again on a long pass fully warmed up, it was a dog. This is a heavy vehicle for a 4 cylinder, 3 speed automatic at altitude but this was slower than usual. I noticed this before on a lower blend of E85 and RUG and ran a tank of RUG and the power was back. Anyone else noticing a power loss on E85 in a non-turbo engine?
