- '10 Sport Trac Limited
Did a little experiment last month where I switched back and forth between 10% ethanol gasoline and No added ethanol ( straight) gasoline.
The difference at the pump here was about 20 cents per gallon with 10% ethanol running $2.79 / gal and No ethanol running $2.99 / gal.
My 2010 Trac has a fuel capacity of 22.5 gallons. I tried consistently to put in at least 18 gallons on every fill up.
With 10% I was getting around 10 -11 MPG ( city) just going around town, short trips, very little highway driving. When I got it out on the highway on a 300 mile trip ( my daughter in in Kansas City), I kept my foot out of it and got a solid 18 mpg at 70 MPH on the 4 lane highway and 75 MPH on the Interstate highways.
When I switched to no ethanol added ( straight) gasoline, my around town ( city ) MPG was up 2 MPG at 13 consistently and the 4.6 V8 really liked the good stuff on the highway / Interstate at a solid 21 MPG.
I think I was getting a little better mileage than this because I went to a taller 265 /65/ 18 tire late last year. I was driving 5 MPH slower knowing that my speedo was around 5 MPH off...
If you do the math, with a full 22.5 fuel load I was getting 236 miles in city and 405 miles highway on 10 % ethanol. Non ethanol was giving me a range of 292 city and 472 highway.
Even more math shows that 10% is costing me $62.78 for a full tank while non ethanol cost me $67.28
BUT....
Fuel cost per mile?
!0% is $62.78 divided by 236 or 26.6 cents per mile city and $62.78 divided by 405 or 15.5 cents highway
Straight gas is $67.28 divided by 292 for 23 cents per mile city and $67.28 divided by 472 or 14.2 cents highway.
Looks like my 2010 Sport Trac like the straight gas better.
Your thoughts? ( Other than I have wayyy too much time on my hands....)
