REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [ 1 ] and automotive engines, though it has not been thoroughly tested for cars and trucks.
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 ...
However, the fuel systems of cars, trucks, and motorcycles sold before the ethanol mandate may suffer substantial damage from the use of 10% ethanol blends. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S ...
Both alcohols have a high octane rating, with ethanol at 109 RON (Research Octane Number), 90 MON (Motor Octane Number), (which equates to 99.5 AKI) and methanol at 109 RON, 89 MON (which equates to 99 AKI). [2] Note that AKI refers to 'Anti-Knock Index' which averages the RON and MON ratings (RON+MON)/2, and is used on U.S. gas station pumps ...
The issue could hurt the biofuel industry, which sees SAF as ethanol’s best chance at growth since electric cars have cut into its market as a gasoline additive. Little to no ethanol will ...
A supply shortage took place for several months during 2010 and 2011 and prices climbed to the point that ethanol fuel was no longer attractive for owners of flex-fuel vehicles; the government reduced the minimum ethanol blend in gasoline to reduce demand and keep ethanol fuel prices from rising further; and for the first time since the 1990s ...
Fuel additives in the United States are regulated under section 211 of the Clean Air Act (as amended in January 1995). The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives.
Amoco — United States, was used as a fuel grade until BP brought it back as a fuel brand in 2017; Aral — Germany, Luxembourg; Burmah — former gasoline brand used in the UK, Australia and Belgium; Sohio — former gasoline brand, now used as a marine fuel brand in Ohio; bft — Germany; Buc-ee's — United States; Budget Petrol ...
