The fuel doesn't really matter..... as long as you aren't running race gas..... I would say stick with the fuel that you are gonna use more often. that and the high octane gas is typically a better quality gas anyway. that is part of the reason why your car runs better with it.

91! is the way to go. try and put chevron. i have a 96 S14 too and my car loves 91 from chevron. i remember when i had my 90 single cam i would run 87 from what ever brand was cheapest at the time. when i would punch it smoke would come out of the exhaust. my bubby told me to switch to a higher grade and i went to 89... no more white smoke! on my S14 when i bought it it had the same problem. the preveuos owner put 87 on it. i started putting 91 on my S14.... i have never had any problems with my car since then.

89 everytime..every 5th or so fill up i put in 93 to burn off excess carbons left over.i also fill the tank everytime..so no 5 dollars here and there

do it on my jeep, 196k and still kicking with no engine work ever done

Ha, thanks guys, was a little worried it might screw with the cylinders...

Now i know

yea most engines are designed to run on the middle grade..unlike an s2k which will only run well on 93. but on a ka, not so much
