Tank #16

I filled up at Meijer last night. Here are the stats:

Price E85: $3.29
Price 87 Octane gas: $3.79 a gallon

So much for Hurrican Gustav! That's cheaper than what I paid two weeks ago!

Gallons E85: 6.518
Gallons 87 Octane: 8.022
Gallons left from tank #15 (@~37.15%% ethanol): 1.86

I'm assuming that the E85 is 74% ethanol, 100 octane.

Ethanol content of tank #16: 38.52%
Octane of tank #16: 94.27

I got 23.7 mpg at 27 average mpg on tank 15.
