Crown Vic tank #4

I had to fill up my Acura with gas because all the E85 pumps were taken.

I filled up the Crown Vic with E85... but I had to fight with a lady over the pump!  Mexican standoff, she was coming in one direction and I in another.  It seems to me that Meijer E85 is becoming more popular.

I filled up at 106432, last tank was at 106166.  17.32 gallons over 266 miles is 15.35 mpg.  Not fantastic mileage!  Mix of highway and suburban driving.

E85 was $1.82 per gallon, 87 octane was $2.02, and premium was $2.42, for a savings of $10.32 per tank.

The car is running flawlessly, no issues with E85 other than fighting over the pump at Meijer!

Crown Vic Tank #3

Last tank started at mileage 105843, and ended up at 106166.  I filled up with 17.345 gallons, for a mileage of 18.622 mpg.  NOT BAD!  I have been driving... more gingerly.  I don't really take it over 70 mph on the highway, for example.

E85 was $1.799 per gallon, regular was $1.99 and premium was $2.49 per gallon.  

Compared to premium (E85 is 96 or 97 octane, and thus more similar to premium than regular), I saved $12.14 per tank.

Car is running fantastically on E85.  Not one issue.

Crown Vic Police Interceptor Tank #2

I filled up last week, but was negligent about posting.

It was at 105843 miles, the last fillup was at 105619.  I filled up with 17.449 gallons of E85 @ $1.799 / gallon.  That works out to 12.8 miles per gallon.

Premium was at $2.49 per gallon, for a savings of $12.21 per tank.

I did more local driving this tank, thus the drop in mileage.

Tank # 32

I got a check engine light right at the end of the last tank.  It went away, and relit shortly after I started driving on this tank, and then went off.

gallons E85: 4.011 @ $1.799/ gallon
gallons 87 octane gas: 9.449 @ $1.899/ gallon

ethanol content of tank: 32.38%
octane of tank: 92.122

Saving per tank compared to premium @ $2.399/ gallon: $6.182

2011 Ford Crown Vic Police Interceptor tank #1

I picked up a 2011 Ford Crown Victoria Police Interceptor, which is a flex fuel vehicle.  I am going to keep track if its mileage on E85.  This is primarily a work vehicle and it gets driven to work on suburban roads and highway, about 50-50 mix.

Today it was at 105619 miles, the last fillup was at 105337.  I filled up with 18.423 gallons of E85 @ $1.759 / gallon.  That works out to 15.3 miles per gallon.

Premium was at $2.45 per gallon today, for a savings of $12.16 per tank.

At some point I will keep track of my mileage on regular unleaded to see how much of a mileage hit I take on E85.  It might be as high as 5 mpg, we will see.

tank #31

It's been awhile since I filled this vehicle up with E85.  The pumps at Meijer have been out of order, I've probably gone through 3 tanks of straight 87 octane gas.  No driveability issues whatsoever.

gallons e85: 4.002 @ $1.759 / gallon
gallons 87 octane gas: 8.749 @ $1.959 / gallon

ethanol % per tank: 28.49%
octane per tank: 91.232

savings per tank vs. premium @ $2.359 / gallon: $5.90

Notice that the differential between E85 and gas has come down to 20 cents from 30 cents per gallon.  I don't know if this reflects winter E85 vs. Summer E85 (more gasoline in the E85 in winter).
