What fuel grade do you put into your S2000?

91 - anything more without some way to modulate the timing is wasting $$$. BTW, anything less than 91 isn't worth the long term cost of engine parts - you save .10 cents per gal. Fill at 1/2 tank level and that works out to save .70...

i think he means drive til the gas light comes on then fill up to only 1/2 a tank. you'll save 70 cents because of the less weight from a full tank.
