Where does octane gas come from?
Today, there are two primary sources of octane used in the U.S. gasoline supply, the BTEX complex (a petroleum refining product commonly referred to as gasoline aromatics), and ethanol.
What is octane made up of?
alkane
Octane is a straight chain alkane composed of 8 carbon atoms. It has a role as a xenobiotic. N-octane is a colorless liquid with an odor of gasoline. Less dense than water and insoluble in water.
What exactly is octane?
An octane rating, or octane number, is a standard measure of a fuel’s ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating.
Is octane a natural gas?
Natural Gas is a smart, low-emission alternative to gasoline and diesel— and it delivers similar horsepower ratings. Premium gasoline is 91 octane, while natural gas has an octane rating of approximately 130.
How is octane produced from crude oil?
The name “octane” comes from the following fact: When you take crude oil and “crack” it in a refinery, you end up getting hydrocarbon chains of different lengths. These different chain lengths can then be separated from each other and blended to form different fuels.
How is the octane rating you see at the pump derived?
The octane number is determined by comparing the characteristics of a gasoline to isooctane (2,2,4-trimethylpentane) and heptane. Isooctane is assigned an octane number of 100. It is a highly branched compound that burns smoothly, with a little knock. On the other hand, heptane is given an octane rating of zero.
Where is octane found in nature?
petroleum
Octane is a hydrocarbon and most hydrocarbon groups are found in petroleum. Petroleum is an oil that is found in nature and under the surface of the earth. It is a mixture of crude oil and natural gas. Octane has many structural isomers.
What is the octane of diesel?
Diesel fuel has an octane rating of 25-40. Mixing 2\% diesel fuel into gasoline will lower the overall octane rating by 1 point.
Why is unleaded 88 cheaper?
The ethanol in Unleaded 88 keeps prices at the pump lower, saving you money! Ethanol also supports job creation. Over 400,000 high-tech, American jobs are supported by ethanol, and Unleaded 88 will assist in creating another 136,000. Who can use it? All gasoline and flex fuel vehicles 2001 and newer can use Unleaded 88.

Does higher octane improve performance?
For most vehicles, higher octane fuel may improve performance and gas mileage and reduce carbon dioxide (CO2) emissions by a few percent during severe duty operation, such as towing a trailer or carrying heavy loads, especially in hot weather. However, under normal driving conditions, you may get little to no benefit.
What is the highest octane fuel?
Octane Ratings. The standard octane fuel for most vehicles as of 2012 had a RON of about 92 and a MON of about 82, giving it an R+M/2, PON or AKI of 87. High octane fuel for cars typically is considered anything with a RON of 95 or higher, a MON of 85 or higher and a R+M/2 of 90 or higher.
