A 10% reduction? Well, my quick research has shown that people are claiming a reduction from 5% to 20%. In my case, with my '05 Civic, it's a drop from 44 to 40 highway and from 38 to 35 or so city. I rounded to 10% which is also about the average of what people are claiming under real conditions.
I've found plenty of anecdotal evidence to support that, but I've also seen plenty of statistical evidence that it's only 2-4% for many vehicles. I've not seen more than a 5% hit on my work truck when I have voluntarily filled with E10.
One point worth noting however is that the vehicle must be able to advance timing appropriately to deal with the slower burn rate it. Perhaps that's where allot of them fall flat. I'm suprised that an 05 would not deal with it well.

Cool sense of humor ya got there... we can always use more of that, especially with what's coming at us.
Back to topic... for my scooter it's also about a 10% hit. I have a 150cc Derbi, which is basically a Vespa ET4. It went from just under 90 mpg to about 80 when the state of Oregon began kow towing to the greener-than-thou ethanol-loving crop- burning murderous whack job liberal scum demanding soylent green gas.
I understand that if you do the math E10, containing ethanol which is touted to be 70% as efficient as gasoline, should be 97% as efficient as gas when mixed. But for some strange reason it doesn't work out that way.
Maybe one of the really smart people here can explain to this 65 IQ nobody why this is so. _________________ Got Dharma?

A drop that big is kinda odd. When/over what route did you last get 90mpg? _________________

Typically surface streets running errands around the east side of 205. A few runs to Corbett. That's my AOA. And I'm very gentle on the gas with very slow starts and an annoyingly (to others) steady 40 mph even in 45 zones. _________________ Got Dharma?

What about the time of year the last time you saw 90mpg? _________________

I can't recall and I don't keep a log, but it was probably during weather much like this, because that's when I do most of my scootering. It's part way through another tank so I'll let everyone interested know the latest when I fill it again. But it could be awhile because the bicycle is getting most of the use now. _________________ Got Dharma?

I started practicing some of these techniques about a month ago, and was a little surprised at how much of a difference it makes. I have a little toyota that I was getting right around 320 miles from a tank (~10/11 gals) and just by doing simple things like speeding up slowly, keeping it around 50-55 and coasting slowly into stopping situations from a good distance, I'm getting about 360-370 miles per tank. Granted, that's not a _huge_ difference, but 50 miles is 50 miles! Every little bit counts I guess.

It's probably the weather then. Going between seasons can add or drop an easy ~5-10%. In order to figure the impact of E10 gas you would need to compare several tanks over the same route in the same weather, other wise you get all sorts of other differences impacting your data. _________________

I certainly hope so. Tire pressure is the second biggest aspect with hypermiling techniques. Keep it higher! So I upped the scooter tire pressure by a few lbs. That may help.
I agree, apples and apples is the only true test. With ICE transport it's tough to do this. Anyhow, the timing is suspicious, so the ethanol remains the prime suspect. I'll know more soon, maybe in a week or so. By then it will be closer to similar conditions, same weather. _________________ Got Dharma?
