I posted this in another thread, but thought Id share it here too since the interest in honda hybrids and ethanol.
Well, its back warm last week in VA and I tried it again. I had done 4.x gallons of e85 to 6.x gallons of regular gas. It did well like 93 octane and gained 10 mpg. Only down side was in the cold weather below freezing I got a trim error.
Well I tried 2.x gallons e85 to 8.x gallons of gas. I actually lost 5 mpg.
Tank 2 with 4.x e85 and 6.x gas is not counted as I made 4 trips to the hardware store for 50 bags of mulch and a trip to the dump. Even with that its at 40mpg and as of yesterday temps dipped to freezing again.
All trips required me to idle inline as lowes has a line and loads your stuff for free. The dump had a long line too as they weigh you coming and going.
Im thinking a 4 to 6 or a 5 to 5 ratio maybe ideal in non freezing weather for max mpg and performance without a cel.
