Snake Oil.
Think of the small number of molecules in the snake oil as compared to the number of molecules in a full tank of gasoline.

Personal experience; Over the counter additives that advertise "6 Points Increase in Octane" really mean that the stale 91 Octane you buy will increase to 91.6 Octane.
The only Octane booster I've used that actually increases Octane as labelled is Torco Mach Series Unleaded. A 32 oz. can added to 10 gallons of 93 Octane gas gives you 10.25 gallons of 104 Octane. No damage to cats, no pulled timing and no knock in 25,000 miles of a high boost turbo 4 cylinder.
Somebody here on the Forum sells it but I lost his screen name and address. Maybe he'll post here.
I don't use it in the 'Vette but it was good for 20+ HP on the Neon.

Yup, the over the counter stuff is worthless.
The only stuff that actually works has Toulene in it. As mentioned above Torco is one such additive.
It should be noted however, that if you are not pinging, you don't need it. Adding it will only decrease efficiency and thus performance.

Unless you tune for the 104 with timing and fuel maps and run it all the time. And don't forget the cost, 3 years ago the Torco was $16.00 a 32 oz. can (in 6 can case quantities) so add $1.60 to every gallon of fuel cost. Probably still cheaper than unleaded race fuel but expensive.

Just stick with the top tier brands - - they will typically contain the beneficial additives- - and avoid the unbranded and low volume or no-name stations. Your Vette will stay happy.

Its needless. Premuim fuel for the c5 is more than enough for octane. You can probably mix the octane boost if you use regular unleaded but it is probably cheaper to run premium. Some say thier c5 runs fine on midgrade as well. I can tell the performance difference between midgrade and premium in my c5.

One time I decided not to add any 101 gas when I went to the strip. I ran 1 mph less (corrected) as compared to my other times. After looking at the KR I'm getting I'm not surprised.
I have also scanned a friends C6 and not only was he getting knock retard on 91 octane, his computer had pushed him down to run on the low octane timing table. That's really the kiss of death because his car was commanding much lower timing across the board than mine. We pulled the ECM fuse and reset his computer and the timing came back, but it will only be a matter of time before he's back on the low octane timing table.
