4. does not increase power

Using an octane rated higher than your vehicle does not increase power.


Explanation:

Octane ratings are measures of fuel stability. These measurements are based on the pressure at which the fuel will automatically burn (auto-ignite) the test engine.

The higher the octane number, the more stable the fuel.

A common misconception is that high octane is equivalent to higher power.
