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

For a compression ratio of 10.5:1, the recommended octane rating is typically around 91-93 octane. Higher compression ratios require higher octane fuel to prevent knocking or pre-ignition in the engine. It is important to use the correct octane rating to ensure optimal performance and to avoid engine damage.

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.

Iso-octane is commonly used as a reference standard to measure the octane rating of gasoline. It is also used as a blending component in gasoline to improve its octane rating and reduce engine knock. Additionally, iso-octane is used in the production of solvents, adhesives, and paints.

Increasing branching in a hydrocarbon generally increases its octane rating. This is because branching reduces the likelihood of pre-ignition or knocking in the engine, which is a common issue with straight-chain hydrocarbons. Branching increases the efficiency of combustion, leading to a higher octane rating.

The octane rating of gasoline is determined by conducting a test called the Research Octane Number (RON) test. This test measures the fuel's resistance to knocking or pinging in an engine. The higher the octane rating, the better the fuel is at resisting premature combustion, which can cause engine damage.

There are 4 different rating systems for Octane.
What country you buy you gas in determines the rating system in force in you area.
There is a very good WIKI article about this and I recommend you read it to understand what Octane rating is in use where you live.

There are many different grades of gasoline, each with a different octane rating.
Early gasoline had very low octane in many cases, from the 1920s to the 1970s octane rating was improved by adding a highly poisonous chemical called tetraethyl lead and ranged from about 90 to 110 octane, most modern cars can run on 87 octane unleaded (now considered "regular" grade gasoline), "premium" grade gasoline is around 90 to 92 octane unleaded, airplane gasoline is typically 130 octane leaded.

The octane rating is a measure of the autoignition resistance of gasoline and other fuels used in spark-ignition internal combustion engines. It is a measure of anti-detonation of a gasoline or fuel. Octane number is the number which gives the percentage, by volume, of iso-octane in a mixture of iso-octane and normal heptane, that would have the same anti-knocking capacity as the fuel which is under consideration. For example, gasoline with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90. Definition of octane rating The octane rating of a spark ignition engine fuel is the knock resistance (anti-knock rating) compared to a mixture of iso-octane (2,2,4-trimethylpentane, an isomer of octane) and n-heptane. By definition, iso-octane is assigned an octane rating of 100 and heptane is assigned an octane rating of zero. An 87-octane gasoline, for example, possesses the same anti-knock rating of a mixture of 87% (by volume) iso-octane and 13% (by volume) n- heptane. This does not mean, however, that the gasoline actually contains these hydrocarbons in these proportions. It simply means that it has the same autoignition resistance as the described mixture. A high tendency to autoignite, or low octane rating, is undesirable in a spark ignition engine but desirable in a diesel engine. The standard for the combustion quality of diesel fuel is the cetane number. A diesel fuel with a high cetane number has a high tendency to autoignite, as is preferred. It should be noted that octane rating does not relate to the energy content of the fuel (see heating value), nor the speed at which the flame initiated by the spark plug propagates across the cylinder. It is only a measure of the fuel's resistance to autoignition. It is for this reason that one highly branched form, or isomer, of octane (2,2,4- trimethylpentane) has (by definition) an octane rating of 100, whereas n-octane (see octane), which has a linear arrangement of the 8 carbon atoms, has an octane rating of -10, even though the two fuels have exactly the same chemical formula and virtually identical heating values and flame speeds.

91 octane is required on all Harley Davidson's.

n-heptane has a zero octane number because it is the reference fuel used to establish the octane rating scale. Its resistance to knocking is very poor, leading to a rating of zero on the scale. Other fuels are compared to n-heptane to determine their octane numbers.

If your car says it requires gasoline with a specific octane rating ...
Well, it will probably operate with a lower octane rating, but it will be very bad for the engine and for your gas mileage.
However, you don't need to use an octane rating any higher than your engine specifies, and there's likely no real benefit to doing so.

Octane refers to a sort of rating when talking about it in relation to gasoline. High octane rated gasoline can be compressed more tightly without spontaneously combusting.

You can use either octane range of 87 to 89. But Daimler-Chrysler recommends to use 89 octane for optimum performance.

Octane rating is the rating given to combustable fuels that shows that fuels resistance to detonation. detonation is also known as knocks. knocks are VERY bad for an engine and efficiencies aswell, because it is simply the fuel going off before it is supposed to (premature combustion). the higher the octane rating (the pump's octane is an average of two different methods of obtaining the octane number) the more resistant the fuel will be to knocking. higher octane fuels WILL NOT increase your fuel economy, if you have observed that such is not the case, then there is another factor that needs to be considered when comparing the high and low octane fuels in your driving regemine.

My owners manual recommends premium for optimum performance. I alternate between premium and regular. If you repeatedly use regular with 87 octane you might notice knocking when travelling uphill. My owners manual recommends Plus with an octane rating of 89. For improved performance it recommends premium with an octane rating of 92 or higher. NEVER use Regular with an octane rating of 87.
