ssdisciple Posted May 15, 2004 Share Posted May 15, 2004 What is the BEST octane booster for maintaining optimum performance of my IS 300? Or is it better to just run "high-test" alone? Thanks!!! Quote Link to comment Share on other sites More sharing options...
bartkat Posted May 15, 2004 Share Posted May 15, 2004 I don't think you need more than premium gas unless you're runing over 7PS boost or really high compression heads of something. Quote Link to comment Share on other sites More sharing options...
ssdisciple Posted May 16, 2004 Author Share Posted May 16, 2004 :D Thanks for the info.....I am still trying to figure out the octane additive deal by doing lots and lots of online research. I just thought maybe you had some first hand experience. Appreciate the INFO! Thanks! Quote Link to comment Share on other sites More sharing options...
