The E85 pump at the Highland Meijer was REALLY SLOW, and I put less E85 in because I was in a hurry. I wanted to go to 5 gallons, but I only did 4.
Gallons E85: 4.002 @ $1.719/ gallon
Gallons 87 octane: 10.182@ 2.019/ gallon
ethanol content of tank: 32.81%%
octane of tank: 92.2
savings per tank compared to premium @ $2.519/ gallon: $8.2926
Next time I'll put in 5 gallons
