Yes, cause of this with older vehicles is that the seals and often the gas lines themselves were drying out , disolving and cracking due to the ethenol content.
Newer cars supposibly use ethenol resistent seals now.
Not a fan of the 10% blend some stations have here in Canada either.
With less energy then gasoline per volume, to me it's like watering down the fuel and charging the same as pure gasoline as you already mentioned.
One + for ethenol though, mixed in it does lower emmisions.

Also, just to add in here. Those of you like me running at altitude. 87 up here is actually 85. You don't need to bump up to mid-grade. Higher altitude doesn't require the 87 octane.

There was a fellow on here a year or two ago who worked at one of those fuel distribution centers in a major city. He said they provided the gas for virtually all of the brands of gasoline around. And he claimed there really, truly is no difference between the various brands--right down to the additives.

Wow
if nothing else I learned a lot from this post, here’s my 
2cents I have try everything can to get a little more performance and gas mileage running any grade fuel from 87 to the 100+ racing fuel has made little difference in ether, I installed a Jet stage 1 all that seemed to do was take away the hesitation on takeoff in the automatic no other changes that I can see noted, later I installed a Volant CAI The only change with it so far is it makes a lot of noise
. Back to fuel I was in Arkansas For a short time filled up with 87 and had a choice of no ethanol I had to try that in FL. There’s no choice the first trip on to the interstate I thought someone had slipped a v8 in the jeep WOW
I could light up the rear tires till the skid control kicked in, 3 tanks there gas mileage up 2.0 mpg with me thinking I had a hotrod 2nd tank back in FL. Lost my hotrod and back to 14.4 mpg mostly city. Now this was just my experience. I think ethanol is the trouble at this point. I am enjoying this post I would like to know more on fuel and the effects of ethanol like it the octane rating lower when ethanol is added?
