imho i think the whole "i need 93 gas or my engine goes kaboom" **** is all bull. Ive driven my gsr wit 120k on it for probably 10k miles using 87 octane and no knock. and that was beating the **** out of it.

i drive my si the same way whether its 87 or 93 octane. i dont develop a knock and runs the same way it does when i bought it, when i put 93 or 87 in. ive talked to honda, mercedes, and infiniti techs and theyve all said it really wont make too much of a difference if u dont put 93 in it.

i dont care too much to put 93 in since its only like a buck or two more than regular 87 octane anyway
