Never could sell me on the 10% when your displacing 10% gas with alcohol that only returns 50% of volume....all 10% does is help some refiner make more $$

 

That's why I only use it when there is about a $1 or more spread on the cost of E85 vs Gas. Try the attached link (same truck as in your post) but use 2.43 as the cost of E85 by me and then 3.29 as the cost of the gas. You should see that there is only about a $125 difference between the 2 for the year. That's the only way I use E85 (and also the convenience of where the E85 station is).

Used the same page but put in 22 as the E85 MPG & 30 as the Gas MPG based on my 2009 2.2 LS HHR. I got 1656.80 cost for 15,000 miles for the year vs 1645 on gas. Drop the cost in the calculate to the $1 spread I use and the E85 cost for the year drops to 1561.40.
