Yes, you're new here. You'll learn that soon enough. Cars with higher cylinder pressure require use of gas with higher octane ratings otherwise the motor will blow up.
Cars like IS300, RSX, (new) Celica GT-S, etc. have high compression ratio something like 10.3:1 or higher and there for must use 91 or greater gas. Also cars that are supercharged have low compression, as low as 7.0:1 up to 9.2:1 but the superchargers already compress the air and therefore the cylinders compress the air further.
