I have always used premium gas in my bike so far.Does anyone have an opinion on how this could effect my ride ?..looking for pros and cons.
are a family of hydrocarbon that are typical components of gasoline. They are colourless liquids that boil around 125 °C (260 °F). One member of the octane family, isooctane, is used as a reference standard to benchmark the tendency of gasoline/petrol or LPG fuels to resist self-igniting
. In a normal spark-ignition engine, the air-fuel mixture is heated due to being compressed and is then triggered to burn (relatively) slowly by the spark plug and ignition system. If it is heated and/or compressed too much, then it will explode when triggered (detonate), or even self-ignite before the ignition system sparks. This causes much higher pressures than engine components are designed for and can cause a "knocking" or "pinging" sound if light, or major engine damage if severe. This can break connecting rods, melt pistons, melt or break valves or other components. The octane rating is a measure of how resistant a fuel is to spontaneously or explosively ignite under such conditions. The higher the number, the more resistant the fuel is. Engines that have aggressive designs (high compression pistons, high intake density and/or temperature) or unusual operating conditions (low-speed, air-cooled engines such as small aircraft) require higher octane fuels.
(upper) has an octane rating of 100 whereas n-heptane
has an octane rating of 0.
The most typically used engine management systems found in automobiles today have a knock sensor
that monitors if knock is being produced by the fuel being used. In modern computer controlled engines, the ignition timing
will be automatically altered by the fuel management system to reduce the pre-ignition to an acceptable level.
The octane rating of gasoline is measured in a test engine and is defined by comparison with the mixture of 2,2,4-trimethylpentane (iso-octane) and heptane that would have the same anti-knocking capacity as the fuel under test: the percentage, by volume, of 2,2,4-trimethylpentane in that mixture is the octane number of the fuel. For example, petrol with the same knocking characteristics as a mixture of 90% iso-octane and 10% heptane would have an octane rating of 90.
A rating of 90 does not mean that the petrol contains just iso-octane and heptane in these proportions, but that it has the same detonation resistance properties.
Because some fuels are more knock-resistant than iso-octane, the definition has been extended to allow for octane numbers greater than 100.
Octane ratings are not indicators of the energy content of fuels
. (See section 4 of this page and heating value
). It is only a measure of the fuel's tendency to burn in a controlled manner, rather than exploding in an uncontrolled manner. Where the octane number is raised by blending in ethanol, energy content per volume is reduced. Ethanol BTUs can be compared with gasoline BTUs in heat of combustion

It is possible for a fuel to have a Research Octane Number (RON) more than 100, because ISO-octane is not the most knock-resistant substance available. Racing fuels, avgas
, LPG and alcohol fuels
such as methanol
may have octane ratings of 110 or significantly higher. Typical "octane booster" gasoline additives
. Lead in the form of tetraethyllead was once a common additive,
but its use for fuels for road vehicles has been progressively phased-out worldwide, beginning in the 1970s.

The above explains Octane rating Regular Octane vrs High Octane. Try different octane ratings and use the one you like I use regular it works well for me.
