I was just giving a heads up really, if he was intending to make a total switch in the future.

However... his current scenario...

(5.5 gallon E85)($2.32) + (8.5 gallons 87 grade)($2.81) = 12.76 + 23.885 = $36.645

With 40% of the mixture offering 30% less efficiency, that brings the total efficiency of the volume down about 12%.

If he bought 14 gallons straight gas at $2.81, it would be $39.34. Hes saving 9% but getting a theoretical 12% loss in efficiency.

Yes, im completely bored at work right now hahah!!
