lower octane gas can be sold if labeled as "sub-standard" or "sub-regular" [11] South Dakota: 85/87 87/89 91 85 octane must be sold with a warning label displayed at the pump. [12] 85 and 86 octane can be sold as regular fuel only in the counties of Butte, Custer, Fall River, Harding, Lawrence, Meade, Oglala Lakota, Pennington, and Perkins.
Octane isomers such as n-octane and 2,3,3-trimethylpentane have an octane rating of -20 and 106.1, respectively (RON measurement). [89] The large differences between the octane ratings for the isomers show that the compound octane itself is clearly not the only factor that determines octane ratings, especially for commercial fuels consist of a ...
Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
Sheetz, which has more than 750 locations in the Mid-Atlantic region is reducing the price of its Unleaded 88 gas by 40 cents per gallon. This gas discount is available beginning Tuesday, Nov. 19 ...
A low octane rated fuel may cause engine knocking and reduced efficiency in reciprocating engines. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car motors still use leaded gasolines. [2] [3]
Octane is a hydrocarbon and also an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the location of branching in the carbon chain .

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 ...
