This is not conclusive proof of anything. The elevation of Geneva is 494 feet while the elevation of Albany is 300 feet. It is no shocker that a car gets better gas mileage going downhill.
Your just lucky it was E85. Consumer reports did comparison with it on serveral of the same vehicle. They reported that they got a average of 27% less milaage per tank.The ethnol industry claimed it was more like 20%. I also have been adivse by mechanic firends to use a intake cleaner before evry oil change in gasoline becuase it tends to leave more carbon with 10% ethnol.Actaully ethnol based gasoline cost mo0re because using it as a 10% additive inst4ead of ohters yields less gasoline per barrel of crude and gets less mileage.That is why it had to be mandated for use by government in gasoline against the refining industries advice.My 2008 manual has a warning not to use more than 10% ethnol gasoline in it. Where I buy it says 10% or less. Watch the pump and of course congress has said it will not mandate more ethnol.
The gas alcohol program has very little to do with efficiency, lowered oil use or reduced emissions and everything to do with the GOP paying off the right wing agribusinesses in the corn growing areas. Without the subsidies for manufacturing the alcohol the prices of fuel corn would fall through the floor and the Midwest would be even more depressed than ever. There has been so much capital invested in this boondoggle that the program, like many useless military programs, is kept alive even if it does not make any economic or environmental sense.
What the hell is "right wing agribusiness?" Like agribusiness cares about political philosophy.
Corn subsidies is an equal-opportunity game played by both sides of the aisle. Take your partisan-baiting BS to the Politics and Other Controversies forum where it belongs.
I never saw any difference in mileage after E-10 was implemented here. I heard a lot of Fox News type hysteria prior to the switch, so I started calculating things over a long haul.
I'm guessing it was because we always had oxygenated gasoline to begin with. Prior to E-10, MTBE was used-- highly toxic stuff. The only thing I noticed with E-10 was my car's fire-up first thing in the morning was slightly slower with E-10, as in a split second slower.
Now approaching 187,000 miles with no drivetrain problems. I'd say 75-80% of those miles were on E-10.
We know that pure ethanol nets between 10-15% less fuel economy...
You add 10% of this 10-15%-less-economy ethanol to your total fuel capacity...
And this magically comes out to 10% less total fuel economy...
Did C-D just invent a new field of wacky mathematics?
they are working on algae based fuels, including diesel and ethanol. but we have to use all types of fuels if we are going to truly power the future, we cant just eliminate some because we dont like them.
I disagree, wasting time and resources on an inferior fuel is inefficient. And when talking about fuel, efficiency is everything.

That is a valid point. If pure ethanol nets 10% less fuel economy, than one should get 99%, not 90% of the energy from E-10. However, pure ethanol will only deliver all that potential if the fuel system is tuned to maximize the energy potential from it. But it's not. My car is tuned to run on gasoline, and the ethanol that is added is utilized much less efficiently than it would be if I were using pure ethanol. I suspect that, without retuning, if you filled your present car today with pure ethanol, it wouldn't even start. So then ethanol added to gasoline is just running through it without contributing to your power, even though your car could be tuned so that it would run on pure ethanol, and then mixing gasoline with the ethanol would have no positive effect.
Presumably, modern cars are designed to utilize some of the energy potential from the added ethanol, but not all of it. I remain to stand corrected by anyone who knows more about this than I do.
