Ethanol vs Ethanol FREE gas mpg?

[Phase]

Has anyone done an mpg average test between your typical gas and ethanol free gas on a modern car? I'm curious about the difference?

How modern is modern?

I ran a tank of E0 in my 2017 fuel injected motorcycle and saw a 3 mpg improvement (53-56), but the next e10 tank I got 61. I would say results inconclusive. The only e0 pump I've found is out of my way by about 5 miles so I don't think it would be worth it for anything I am actively driving (if its gonna sit I try and fill up with e0).

just any cars after 2010 i guess

lots of articles and the few rare tests ive found online say about a 10 percent mpg increase

60mpg in my ioniq getting boosted to 66mpg would be great with no work involved. the price difference isnt worth it obviously, but im curious just to see what type of high numbers i could achieve

It's about a 3.5% difference, which is the difference in energy content. Most people see larger than 3.5% variance from one tank to the next, so anecdotal reports vary.

Difference in energy content is much higher, ~30% between E10 and E85 - here in Finland there is no zero ethanol fuel available.

Difference in fuel consumption depends, due to higher octane number of ethanol - if engine management is advanced enough, it can adapt ignition timing and boost pressure to match those qualities.

Watching only mpg numbers, it looks like gasoline is way to go, but if you care about fossile fuels burnt and carbon emissions, it's a different story.

Long story short, after my aero mods, I want to fill up with ethanol free gas and try to squeeze 800 miles of range out on a single tank of gas for an experiment or YouTube video. In theory if I go even slower, I could do 900 miles from full to completely empty…

If you don't have a closer source there's the I-5 truck stop at Coburg, OR.

I know plenty of locations and see a lot around oregon. And see even more on road trips. Was going to wait till summer when weather is warmer and I have my mods in place before putting in the pure gas

I just watched a video today, where it was tested and found that E10 87 pump gas being sold today, in the midwest, is actually 2-6% ethanol. It isn't anywhere near the "up to" figure.

Will adding nitro or noz boost my mpg too or just speed?
