What gas is needed for RSX and Honda Si?

So I'm about to get either an 2006 RSX type S or a 2006 Honda Si. And I wanted to make sure I HAD to use premium gas or not and all websites had said yes. But what I want to know is if their are certain gas stations I have to go to. Or can it be any gas stations?

If you buy a sporty car or a sports car, expect to have to use premium, or get buy a moped.

Dude, look at the octane rating, that is what matters.

Kerosene

The rsx has a k20z1 motor and the si has a k20z3 motor, they're nearly identical and both are high compression motors that require 93 octane, anything less is bad for the engine and will cause knocking and eventually damage.
