<<<If you run the averages on the numbers above, the consumer is missing out on 5-10 cents of additional true savings due to ethanol. That also equates to $7.5-15 billilon dollars the refiners are potentially pocketing on an annualized basis due to ethanol blending in the US. That's some big numbers folks that stays in Houston and doesn't make it back to the average consumer.>>>
But the "good" news is that the Feds are socking them a whopping 39% in taxes, much of which gets passed on to the common folk in the form of entitlements.
E85 would get much better mileage if the engines were designed to run on it exclusively. Even though it has fewer BTU's than gasoline, the higher octane level would allow for a higher compression ratio in an engine without detonation, which would increase power and mileage. With a flex-fuel vehicle, a lower compression ratio must be used to accomodate gasoline which kills the mileage of E-85. The higher the compression ratio of the engine, the less the mileage difference between the two fuels.
An interesting tidbit on CAFE standards...... For the purpose of calculating the average fleet fuel economy, if a Silverado is rated at 18 mpg on gas and 16 mpg with E85, it's CAFE number for the government is 34. (18 + 16) Because the manufacturers must maintain a certain average fleet fuel economy rating, (around 25 mpg) by selling more flex fuel vehicles they can sell more trucks. Without this loophole in the law, Ford & GM would miss the CAFE minimums by a wide margin and would only be able to sell about half the number of trucks and SUV's which they currently sell. The law encourages the use of alternative fuels but not less fuel.
