It is used in turbo vehicles because they run at higher temps and the lower octane will ignite prematurely under higher boost, this is called detonation. On a NA vehicle that isn't highly tuned it will provide little performace value.</td></tr></table><span id='postcolor'>
WRONG
if an engine was designed to run on high octane, running high octane in it will produce MORE POWER and will BE FASTER. if you don't believe me, read up on European Car's project M3, or C&D had an article not too long ago about it.</td></tr></table><span id='postcolor'>
even in our cars, The ECU is smart enough to detect when you have shitty gas in the car, and will retard timing to prevent detonation.. This WILL reduce you power. Run premium, and let the car do what it was designed to do. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

I think 89-90 S13's only req. 87 or 89 up.
