false. higher octane for higher compression motors b18b isnt a high compression motor. youd just be wasting your money and killing your catalytic converter at the same time.

are you serious? everything you said was false..... higher the octane the cleaner the car runs... higher octane the better gas milage you get... higher octane better performing engine.. cleaner everything...

^ more false, lol.

This has been discussed before. Higher octane is better for high compression or turbo cars because it helps prevent detonation. There really is no point in running higher octane gas on a normal unmodded N/A engine.

nothing i said was false. your cat converter will die eventually because it will have to burn off the fuel that your motor didnt because the compression was too low for proper combustion. mileage will remain the same, there will be no significant difference in the amount of air youre polluting. and i would imagine it would eventually foul up your o2 censors. bottom line, dont do it if your motors internal work is stock or you dont have forced induction mods.
