Wifey's van

I just so happened to be in the middle of corn country driving my wife's van, and I saw E85 for $1.67 a gallon.  I took the opportunity to top it off with E85.

I got exactly 8 gallons of E85 before it clicked off, it's a 20 gallon tank, so roughly 40% ethanol.

I noticed that it lost about 4 mpg on the ride home, but no check engine light or any drive-ability issues.

Every once in a while if I'm driving this van alone, I'll add 4 gallons of E85, just to keep the fuel system clean.

Crown Vic Tank #14

E85 was $1.75 a gallon today.  87 octane gas was $2.05 and premium was $2.55.


I did a partial fill in between this tank and the last tank, I did not document it.  I forgot to get a receipt!

I was at 109474 miles, last tank was at 108176 miles, for 298 miles on this tank.  I filled up with 17.395 gallons, for 17.131 miles per gallon.  I had more highway miles this tank and less a/c.

I saved $13.71 on this tank by using E85 vs. premium, not considering the mileage penalty.

Acura update

The Acura is sitting at 165k miles, more than 10k miles running on E30 to E40, with no issues.

My son is learning to drive and is mostly driving it.  For simplicity's sake, he has been filling up with 87 octane, not mixing E85 in like I was.

So, from now on, most if not all updates will be for the Crown Vic, just documenting mileage with E85 and gas.

Crown Vic tank #11

E85 was $1.85 a gallon today.  87 octane gas was $2.15 and premium was $2.65.


I was at 108469 miles, last tank was at 108185 miles, for 284 miles on this tank.  I filled up with 16.964 gallons, for 16.74 miles per gallon.

I saved $13.57 on this tank by using E85 vs. premium, not considering the mileage penalty.

Crown Vic tank #10

Remember, the last tank was gas, not E85.

E85 was $1.99 today.  87 octane gas was $2.19 and premium was $2.69.


I was at 108185 miles, last tank was at 107863 miles, for 322 miles on this tank.  I filled up with 16.343 gallons, for 19.7 miles per gallon, on GAS, not E85.


So I lose about 3 to 3.5 mpg when using E85 vs. gas.

I saved $11.44 by using E85 vs. premium, not considering the mileage penalty.

Crown Vic tank #9

Unfortunately, both E85 pumps were occupied this morning, and I had to fill up with straight gas.  On the positive side, now I can see what my mileage on gasoline (E10) is.

I was at 107863, last tank was at 107580, for 283 miles on the tank.  I filled up with 17.293 gallons, for 16.37 mpg.

E85 cost 2.05 per gallon, E10 gas cost 2.25 per gallon, and premium cost 2.75 per gallon.

How much ethanol/ gasoline is in E85

My buddy has a flex fuel F-150.  He also has a scanner that plugs into the OBD port and tells him how much ethanol is in the fuel.

His last fillup at Meijer was only 60% ethanol.  Before that he filled up at Family Express and it was 80% ethanol.

I borrowed the scanner, I'll try and see if it works with my Crown Vic.

Crown Vic tank #6

E85 was $1.18 today.  87 octane gas was $2.38 and premium was $2.88.

I was at 107002 miles, last tank was at 106699 miles, for 303 miles on this tank.  I filled up with 18.411 gallons, for 16.45 miles per gallon.

I saved $9.87 by using E85 vs. premium, not considering the mileage penalty.

Crown Vic tank # 5

E85 was $1.99 today, I always like getting fuel for less than $2 a gallon. ;).  87 octane gas was $2.19 and premium was $2.59.

I was at 106699 miles, last tank was at 106432 miles, for 267 miles on this tank.  I filled up with 17 gallons, for 15.7 miles per gallon.  That seems to be what I get on E85 in mixed driving, 1/2 highway and 1/2 local suburban.

I saved $10.20 by using E85 vs. premium, not considering the mileage penalty.

The car is running outstanding on E85, you have no idea drive ability wise that you're not running regular gas.

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).
