I have been using this stuff every now and then, anad there is a definate difference in feel. It also feels much smoother for me on acceleration. Without it, the car has a kind of raspy feel. But with it, it is clear as day. I even think my exhaust sounds a little different with it. I will post a pic when I take it.

what kind of octane fuel are u using w/ the octane boost???

 

CA = 91 Octane

So for us that can get 93 and 94 easily probably isn't worth it.

 

Here in Cali, we only have 91. So I feel, that I must use it, and Hey turbo power, I was looking for technical types of responses. I forgot to mention that I have NA mods on the car with tuning, and was looking for more info on that.

 

am i missing something here ... in the uk ordinary fuel is 95 ron and the s2000 takes 98 ron freely available! is the us rating different?

 

its was 93 in tx just moved to Cal and the best i can find is 91 My dad tells me back in the day it was all 100 or more. Oil companys cutting corners.. costs more to make Higher Octane fuel..

 

US law requires that octane ratings at the pump be:

(RON + MON)/2

so we're comparing apples to oranges here.

 

The octane booster claims that with 10 gallons it will jump you up 7 points, but I think it might be less than that, so I use a full bottle with like a half a tank, plus it has the nitro in it. The bottle actually states that it is not legal to use on the street. Ha!
