[QUOTE="ionbeam, post: 1108790, member: 277"] Since ethanol raises octane it lets you raise compression, preferably using a positive pressure intake that is variable and you get power and mileage back. As always the driver will influence mileage. Using a fuel type sensor to fine tune the fuel injection pulse width would then let you actually see noticeable improvements in mileage. The Consumer Reports article was accurate for what it reported, but was [S]seriously one sided[/S] not balanced by not talking about why the mileage was low or the available technologies that could improve power and mileage. This is not a totally immature fuel source, Brazil has been using ethanol in varying proportions for 37 or more years. AFAIK, Brazil does not allow 100% gas anyplace but is moving for E100 vehicles (100% ethanol). The only difference is American vehicles run on corn and the Brazilian vehicles run on sugar cane. Whiskey vs Rum [IMG]https://www.fjrforum.com/forum//public/style_emoticons/default/smile.png[/IMG] Edited to add: The statements about mileage and power is based on what I have read. The guys at the track like being able to run higher compression. Edited to add: Which I guess makes some Forumites rated to run on E85 to E100 too. [/QUOTE]
