Born On The Cob: 680 Miles With E85

Last week, I reported on my decision to use E85 fuel in my 2009 Town Car for a week or so. How’d it go? Well, as it so happened, I accidentally veered off the road while texting and killed a

pretty solid “sexting” session with one of automotive journalism’s most prominent, and beautiful, distaff contributors. (I apologize for the placement of the “jump” there, but I’ve been told to “get my clicks up” or something to that effect.) Back to the math.

In the original article, I indicated that my “target mileage” to break even with E85 usage was 17.8mpg, based on my gasoline mileage of 21.4 average and the $2.29/$2.79 pricing of E85 and 87 octane fuel. The first tank was very promising; I averaged 18.1mpg with no difficulty.

The second tank was still $2.29, but gasoline was $2.63. This made my target mileage 18.6mpg, but from the moment I refilled the mileage began dropping precipitously, eventually settling at 16.4. Worse yet, twice during my morning commute I noticed a low-speed stumble. Was it because I had fuelled up at a different E85 station?

Over the course of the first 28.5 gallons, I averaged 16.4 mpg total. My third fillup, still priced at $2.29 but this time facing a gasoline price of $2.87, came just as temperatures in Ohio fell to the 45-degree Fahrenheit range. A Halloween weekend of serving as a designated-driver taxi for some female friends found me pulling into my driveway at 3:05AM, having burned thirteen more gallons and lowered my overall mileage to 15.7. There was a persistent smell of alcohol in the car, but this turned out to be due to the “to-go cup” of Abolut Apeach that somebody spilled down her costume. It turns out there was no cotton between her and the seat to absorb the drink, but I’m told that vodka can sterilize almost anything, including corrected-grain leather.

Today’s commute, done with the windows down just in case I got pulled over by the Ohio Highway Patrol, raised the average back to 15.9 and burned all but a gallon or so of fuel. I’m now sitting in a corporate cafeteria doing the math. A rough total of 42.5 gallons, purchased for $97, carried me approximately 675 miles. Assuming there would have been negative temperature effect for using standard gasoline, something of which I am not completely certain, I would have needed 31.5 gallons of gasoline to cover the same distance. Averaging out the cost of gasoline over the past eight days, I would be looking at about $87.

This is the kind of sample size and scientific methodology that probably makes Michael Karesh vomit directly into his pocket protector, but if you want some genuine, peer-reviewed literature, I suggest you read Social Text. The raw numbers indicate that it cost me ten bucks to run E85.

The intangibles aren’t as clear-cut. Using E85 decreases my range, shortens my refuel interval, and possibly causes the Townie to be a bit upset in the mornings. On the other hand, it raises the price of food, and I’m told that’s about all this country exports nowadays, so that’s a positive thing. right?

I’m semi-tempted to keep running the yellow-handle fuel for a week or so more. I will probably go through another 30 gallons or so before I leave for Toronto on Friday for another weekend catastrophe. If I can find an E85 station in Buffalo I might be able to run the Lincoln on corn for my entire trip and purchase no fuel at all in tax-rapacious Ontario.

I will leave the last word to one of my Halloween party pals. When informed that her short-wheelbase limo for the evening was running on alcohol, she frowned for a moment: “What are we going to drink, then, if the car drinks all the good stuff?”

    Jack, this is epic stuff. the title is hilarious, and the methodology is very representative of how normal people calculate the difference between the two fuels...

    Wow. I can do 675 miles on 15 gallons of diesel and there's no corn involved! And if you're in Ontario, don't use the yellow handle without making sure what it is first. Yellow handles are sometimes diesel. The Town Car probably wouldn't approve of that.

  • CanadaCraig You can just imagine how quickly the tires are going to wear out on a 5,800 lbs AWD 2024 Dodge Charger.
  • Luke42 I tried FSD for a month in December 2022 on my Model Y and wasn’t impressed.The building-blocks were amazing but sum of the all of those amazing parts was about as useful as Honda Sensing in terms of reducing the driver’s workload.I have a list of fixes I need to see in Autopilot before I blow another $200 renting FSD. But I will try it for free for a month.I would love it if FSD v12 lived up to the hype and my mind were changed. But I have no reason to believe I might be wrong at this point, based on the reviews I’ve read so far. [shrug]. I’m sure I’ll have more to say about it once I get to test it.
  • FormerFF We bought three new and one used car last year, so we won't be visiting any showrooms this year unless a meteor hits one of them. Sorry to hear that Mini has terminated the manual transmission, a Mini could be a fun car to drive with a stick.It appears that 2025 is going to see a significant decrease in the number of models that can be had with a stick. The used car we bought is a Mk 7 GTI with a six speed manual, and my younger daughter and I are enjoying it quite a lot. We'll be hanging on to it for many years.
  • Oberkanone Where is the value here? Magna is assembling the vehicles. The IP is not novel. Just buy the IP at bankruptcy stage for next to nothing.
