The difference was 0.07 in favor of 98E5 on average, meaning that using 95E10 gasoline, which has a higher ethanol content, increases consumption by 0.7%. When the measurements are normalized, the difference becomes 1.0%, a result that is highly consistent with an estimation of calorific values based on approximate fuel composition, which came ...
87 89 93 Missouri: 87 89 91/93 Some Phillips 66, Break Time, and Conoco stations sell 91 octane premium. Southwest Missouri in the Ozark Mountains and Mark Twain primarily only sell 87/89/91 Montana: 85.5 [7] 88 91 Nebraska: 87 89 91 Nevada: 87 89 91 Eastern Nevada primarily uses 85/87/91 octane ratings. New Hampshire: 87 89 93 New Jersey: 87 89 93
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without causing engine knocking.The higher the octane number, the more compression the fuel can withstand before detonating.

According to RFA the ethanol industry created almost 154,000 U.S. jobs in 2005, boosting household income by $5.7 billion. It also contributed about $3.5 billion in federal, state and local tax revenues. [45] The return on investment (ROI) to upgrade a service station to sell E15 is quick given today's markets.
In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol used as fuel. Sugar cane plantations covered 3.6 million hectares of land for ethanol production, representing just 1% of Brazil's arable land, with a productivity of 7,500 liters of ethanol per hectare, as ...
