I filled up at Meijer this morning. Here are the stats:
Price E85: $3.74 a gallon (YIKES!)
Price 87 Octane gas: $4.24 a gallon
Gallons E85: 5.998
Gallons 87 Octane: 9.004
Gallons left from tank #11 (@~38.501% ethanol): 1.398
I'm assuming that the E85 is 79% ethanol, 100 octane.
Ethanol content of tank #12: 37.670%
Octane of tank #12: 92.222
Tank 11 finished with a mileage of 24.2. Average speed was 31 mph.
Price of E85 is insane. I'm pretty sure that this is the most I've ever paid for it. Come on, Meijer, give us a break! My spreadsheet is still showing that E85 should be about $3.10 or so.
