Assume the premium at 93 octane and the regular at 87. Putting in .78 gal reg and then filling up with premium gives you a blended octane of about 92.6. Don't sweat it. You'll be lucky if every tank of premium is even that good.

You're fine. And just so you know, the octane booster stuff is really a myth anyway. We used to test that, and it doesn't boost the octane at all. There are some chemicals that allow it to burn cleaner, and sometimes more efficiently, but the only way to boost octane is add BTUs to the fuel....

you will. and i pity the person who buys your used S2000. wait til one of those detonations burns through a valve and destroys a cylinder. then when you're spending several thousand on repairs, you can come back here and tell us how you've "never had any problems". oh wait, but yeah i guess you'd know better than honda engineers about what kind of gas your car needs right? i mean, i assume you were one of the engineers who built this engine, otherwise you'd never say or do something so foolish right?
you don't deserve to have this car, because you obviously have no clue how to take care of it. i seriously feel bad for your car.
