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.
