I'm being facetious -- I mean that the octane boosters are not regulated in any way shape or form, so use at own risk.

That said, I wouldn't count on them to do anything especially good OR bad (other than drain your wallet a bit).

Seriously, if anyone here buys their new Z and thinks the dealer topped it off with regular, the best thing you can do is drive around gently (i.e., no flooring it, no redlining it -- not a great idea if breaking in a new engine anyway...), burn through 1/4 to 1/2 a tank, and then top off with high octane.

Hell, if you can find it, some Sunocos have 100 AKI at the pump. Half a tank of that plus regular will get you where you need to be (although I believe fuel blending winds up being not quite that simple in terms of effective octane...).

That's a much better way to go than adding a couple bottle of octane booster, crossing your fingers, and driving however you would normally.

Oh, and lookie what I found... http://www.fueltechexperts.com/2008/...which-is-best/

Remarkably, a few of them added a point or two of RON (although, keep in mind that AKI is the average of RON+MON... actually, a good rule of thumb on RON to AKI conversions is RON*.95=~AKI value -- example, our car requires 96 RON or 91 AKI, 96*.95 = 91.2), most added less than a point.

Still not going to be very helpful on a tank of 87. Siphon or gently use up, top off with high test. Done.

Find a gas station that sells 100 octane race fuel. They are actually quite common. I tried octane booster and had no results. If you mix half race fuel and half 91 octane you get 95.5 octane. That seems to be the sweet spot for my 370z. I tried pure 100 octane but it didn't run as good as 95.5. There are many octane calculators online. You can mix 91 and 100 to achieve whatever octane you want.
