dude... it's a rating system of how clean the fuel burns.
What?
It's the octane rating.

To understand octane rating, you need to understand a little bit about how car engines work.
The engine?s power comes from carefully controlled explosions of gasoline/air mixture inside the engine. To control the explosions, the gasoline must burn at exactly the right rate. This is controlled by the gasoline?s chemical composition.
Gasoline is a mixture of many chemicals that burn at different rates. One chemical that burns at the right rate is isooctane. A chemical that burns too quickly is n-heptane. To describe how fast a gasoline burns, a scale was developed using these two chemicals. Isooctane is defines to have an octane rating of 100, which n-hepatine has an octane rating of 0. Octane ratings compare the burning characteristics of gasoline to mixtures of isooctane and n-hepatane.
For example, if a cheap gasoline burned the same way as a 50:50 mixture of isooctane:n-heptane, the octane rating would be 50. Gasoline with an octane rating of 87 burns he same way that a mixture of 87 percent isooctane and 13 percent n-heptane would burn.
Usually, only cars with high compression engines need anything higher than 87 octane. See your ownwers manual.

It relates to the octane content.
Octane actually retards the flammability of fuel, allowing for higher compression ratios before spontaneously combusting.
