Best gas in town?

Nothing fancy, I use a Quick Fuel Technology Echecker, not really intended to test E10...

Here's what I had found before I bought the Echecker, it may help. Unfortunately, you'll have to math

Tested the e85 blend from the Petro Serve on 45th St and 9th Ave SW, 74% ethanol.
-
O how I wish I were a cemistry major and i could do this in the lab with some spare time.
Come to think about it your getting a lot or low ratings on your E-85 so I would assume the same for 10%. Though maybe there dumping more in to save cost and its really like 15% as thats what its going to jump up to in the future.
-
testing E85 is pretty much a worthless endeavor.
Read the SAE papers on it, there is virtually no difference in knock capability and power of E fuels from 50-85%. In fact you need to be OVER 85% to make any measureable difference with E98 only being marginally better than E85. Ive been using E85 for 7 years, and have never tested it once, never had any issues, and even ran the same tune on e85 and e50 with a VERY minor fueling adjustment, about 2%. In short its a GIANT waste of timeAlso E10 is certifiable up to 15% ethanol content with alot of it being 13-14% as an average

I disagree, I've seen pretty large swings in my fuel trims switching blends. You could easily damage an engine switching from E70 to E85 and running lean before the trims sort it out. I make sure to stay in closed loop for a day or two before I run it hard.
-
Sorry dude but if you are pretty obsessed with your "tune", if your that close to the ragged edge you might want to back it off a tad. I run open loop speed density and never see more than .2 AFR difference ever. If the car runs drive it and dont waste so much time obsessing about tuning

Filled up Monday at Petro Serve on 2nd downtown - off the scale on my checker, but looks to be about e60. Starts great in the morning, but it's definitely pushed my fuel trims.
It's settled out a little better than this, but this was the low point...
I need to pull a log on it - if it looks clean I may run this all winter.
EDIT - Logs are clean. Idle trim is pegged at -15, but it seems to run fine.

New tuner doesn't like Stop-N-Go's 91 octane, apparently. Still managed 6 more horsepowers and 11 more torques than my old e-tuner.
So, with the gas tune buttoned up, time to move on to e85.
Cenex @ 25th St & 23rd Ave - 68%
Don's @ 25th St & 52nd Ave - 95%Dafuq. <sigh>

How are you testing you e content? Maybe go back in a couple days and see if it is consistent.

Quickfuel Echecker.
I went back the next day actually and tried a different pump - got e60. Went back to the pump from the night before and got e75. I called to ask about it, and they said that the e85 isn't blended at the pump, it's straight from the tank. I think the lower e content samples can be blamed on e10, 20 or 30 in the lines from a previous customer, but I can't explain that e95 sample. I measured it twice.
