Thats my point slogfilet.
I believe my engine is NOT as efficient on the E10 mix hence why I am seeing such a larger drop in FE.
but its not an efficiency of the engine problem. its a compatibility of the fuel problem.
Dump diesel in you gas engine and its not your engine's fault it runs like crap.
"An engine mechanically adapted around E85 will be much more efficient as the video demonstrates. "
note he did NOT say its more efficient and certaintly not MUCH more efficient.
He said it was "almost as" efficient as the NON Ethanol based fuel. Though to be fair he was comparing it to "diesels" but the FE difference in gas and diesel engines on that scale (150/250 sized vehicles) is not much different and he is using an optimized V6 versus a V8.
ie he is doing a lot more than JUST optimizing for ethanol. he is using a small lighter engine as well.
