Calculating octane is a compex process, but the formula is simple (the difficulty is getting the values from the manufacturer). Gasoline pumps typically post octane numbers as an average of two different values. Often you may see the octane rating quoted as (R+M)/2. One value is the research octane number (RON), which is determined with a test engine running at a low speed of 600 rpm. The other value is the motor octane number (MON), which is determined with a test engine running at a higher speed of 900 rpm. If, for example, a gasoline has an RON of 98 and a MON of 90, then the posted octane number would be the average of the two values or 94. See related links for information about computing octane numbers.
the higher the octane the better it burns and you get less build-up in your pistons, some vehicles recommend higher octane ! these are most likely used in the faster cars for drag racing to get up more speed and when it reacts, it glows a bright white
The number is zero. It has no moons.
Octane and methane are both saturated hydrocarbons and follow the formula CnH2n+2. The only thing that's different is the number of carbons (and hence hydrogens) in the backbone. Octane has 8 carbons and has formula C8H18. Methane has 1 carbon and has formula C1H4.
Heptane has the number 0, and the number assigned to isooctane is 100. These two materials are used to grade the octane rating of petroleum fuels.This is called bracketing method.
The octane rating of methanol depends on the octane rating scale measurement type used, n-Heptane is the zero point of the octane rating scale then the octane rating of methanol is 115

Octane has not special application excepting the so-called octane number.
93 octane works best.
Octane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane rating of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
RON= research octane number
100 octane. This is why aviation fuel (avgas) is typically called 100LL, which stands for 100 octane, low lead.
Research Octane Number 95
The octane number is a measure of performance of a fuel. It is measured relative to pure isooctane which is given an arbitrary value of 100. It is possible for fuels to have an octane number higher than 100. The higher the octane number the more compression it takes for the fuel to detonate. Higher octane fuel is used usually in high performance vehicles where the engines have higher compression ratios. If the octane number of a fuel isn't high enough it can lead to engine knocking this is where the fuel detonates before the fuel is at its maximum compressive state in the engine, this can cause damage and lower performance.

ISO-octane, or 2, 2, 4-Trimethylpentane is mainly used in the production of gasoline. When added, it reduces engine knocking. The addition of ISO-octane is what is referred to when a gasoline's octane rating is referred to, and a 100 rating is when only ISO-octane is added to the gasoline. A zero rating is when only heptane is added, so the various ratings refer to the ratio and blends added to fuel.
