Methods of increasing the octane number of gasoline include blending it with higher-octane components such as ethanol or adding octane-boosting additives like tetraethyl lead or MTBE. Refining processes like catalytic cracking can also help to increase the octane number of gasoline by producing higher-octane hydrocarbons. Additionally, changing the fuel composition or utilizing advanced fuel injection systems in vehicles can help optimize the combustion of gasoline to improve octane performance.
The guide number for gasoline refers to the ignition quality of the fuel. It is indicated by the octane rating, with higher numbers indicating better resistance to engine knocking or pinging. Gasoline with a higher octane rating is typically recommended for high-performance or turbocharged engines to prevent knocking and improve overall engine performance.
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 1988 Porsche 944 is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. Using a lower octane fuel can lead to engine knocking and reduced performance.

The molecular formula of octane is C8H18. It doesn't really have a "symbol."The "octane" in gasoline is actually "iso-octane" or 2,2,4-trimethylpentane. It has the same molecular formula, but the atoms are arranged differently than in n-octane.
The most common additive is MTBE.
There is no octane in gasoline... it is the equivalent of octane.
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.
The gasoline octane number, often referred to as the octane rating, measures a fuel's ability to resist knocking or pinging during combustion. The higher the octane number, the more compression the fuel can withstand before igniting. Common octane ratings for gasoline include 87 (regular), 89 (mid-grade), and 91-94 (premium). The guide number helps drivers choose the right fuel for their vehicles, ensuring optimal performance and efficiency.
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 amount of resistance that a fuel has to detonation. The higher the number, the less likely it is that a particular fuel will detonate in a particular engine. The number is as compared to a standard fuel (not necessarily gasoline)
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.
FUEL RECOMMENDATION NISSAN recommends the use of unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research octane number 96). If unleaded premium gasoline is not available you may use unleaded regular gasoline with an octane rating of at least 87 AKI number (Research octane number 91), but you may notice a decrease in performance.

Copper will not lower gasoline octane. In fact, copper is commonly used as a catalyst in catalytic converters to help convert harmful pollutants in exhaust gases into less harmful substances. It does not have a direct impact on the octane rating of gasoline.
