What Octane is premium gas?

The primary element separating premium gas from regular gas is their octane ratings. Premium gas has an octane that can range from 91 to 93. The actual octane rating depends on where you get the premium gas. There are some places where its octane rating is more than 93. On the other hand, regular gas has an octane rating of 87.

What is the formula for the combustion of octane?

Combustion Reaction. As is the case with other hydrocarbons, octane undergoes hydrocarbon combustion, combining with oxygen to form carbon dioxide. The balanced chemical equation for the complete combustion of octane is: 2C 8 H 18 + 25O 2 → 16CO 2 + 18H 2 O + Heat Energy
