1 gallon of E10 has ~111,000 btus (~3.5% less than gas)
1 gallon of E15 has ~109,000 btus (~5.2% less than gas)

So you should be getting ~5% (not 7% as I said earlier) worse mpg on E15 while, in theory, consuming ~15% less oil.

As Freebeard mentions, it does take considerable energy to produce ethanol (~35,000 btus worth of energy are needed to get ~76,000 btus worth of ethanol) so it isn't a "green" source of energy like the corn industry would like us to believe. But ethanol can be produced 100% domestically so your money stays in America rather than going to hostile leaders like Vladimir Putin, Saddam Hussein, Osama Bin Laden, etc.


Edit: And to be fair, it takes a lot of energy to produce 1 gallon of gasoline too - especially if the crude oil has to be transported half way around the globe.

my vehicles Say NO to e15-e100 so it does not really matter what you say it will not change the physical components to my vehicles so if the fuel is pouring out of the gas tank means I WILL have to fill it up more there by wasting more oil

Facepalm...

NET Oil saved will be negative, pollution will be massive from the hydro carbons leaking into the air so this means using e15 is still debunked

During the summer months I get the same fuel economy on e15 as I do with e10.

If it is different it falls into the margin of error

I wish they would just install more levels of ethanol as an option, ive had good success with power/throttle response with around 20-25%. FE drops but honestly I don't care when the car runs freaking terrific just by changing fuel. The extra octane gives really nice knock resistance in summer.

I am favorable to ethanol, even though it would be better to give customers a choice, and even though corn-based ethanol is oftne pointed as "evil" it's not a fully accurate claim. In my country the most common feedstock for ethanol is sugarcane, but corn and other crops may have some advantages in other regions, and distillery grains can be used to feed beef cattle and other livestock, leading to a faster weight gain and increasing the organic matter to protein conversion ratio.

112 octane fuel. It's popular with the muscle car communities. You can do a tune and a gm flex fuel sensor kit most of the time to accomplish it. Also sometimes injectors fuel pump etc depending on duty cycle. Too bad reddit bot deleted the thread but I see the Brazilian gen 3 prius uses flex fuel and doesn't have EGR either.

Even though a handful of Priuses served as test beds for ethanol, ultimately the flexfuel capability was only fitted to the Brazilian-built Corolla hybrid version in late-2019, and more recently the Corolla Cross. IIRC the Prius is not available in Brazil anymore, as the local hybrid Corolla took over its role. Not sure about the absence of an EGR though...

You should find one and take a picture.
But yeah there was a thread on prius chat referencing it and people acknowledge it was real but its a reference to a deleted photo now all I do not know.

Not so likely to find, if you refer to a 3rd-gen or 4th-gen Prius flexfuel test bed, yet I often see flexfuel hybrid Corollas even operating as taxis.

Are 2010-2015 Priuses very common there?

Not really. The Prius only became a captive import here in September 2012 IIRC.
