Try to revisit your manual bro. every car has a different octane rating requirements.

The octane rating is a measure of the autoignition resistance of gasoline (petrol) and other fuels used in spark-ignition internal combustion engines. It is a measure of anti-detonation of a gasoline or fuel.
Octane number is the number which gives the percentage, by volume, of iso-octane in a mixture of iso-octane and normal heptane, that would have the same anti-knocking capacity as the fuel which is under consideration.

The octane rating essentially a measure of how well the fuel will compress in preparation for burn in the standard gasoline internal combustion engine and is related to the quality of combustion at average engine temperature and pressure. Iso-octane has an octane rating of 100, by definition. Cars today are designed to have 85 to 95 octane fuel. Since Gasoline is a mixture it's octane rating can be manipulated by changing the relative amounts of its constituants.

sa civic 06 po? ano po ba dapat octane?

Whatever the manual states. But the car should be unaffected by lower octane grades, since most Hondas are tuned to run on regular gas.
