I just got a low milage engine swapped in...and I was wondering wut octane level I should use....I'm not sure if it's a 5sfe or a 3sfe all I know is it's JDM....and I read that using regular octane levels makes the engine preform better. Is that true?

It never hurts a car to run stupidly expensive high octane fuel. Just hurts your wallet.
