octane boost...is it worth the $$
found this.. thought some of you might find interesting
A typical 92 or 93 octane pump gas contains hydrocarbons that evaporate in a range from about 80 degrees F to over 400 degrees F. Rockett Brand 100 Octane unleaded contains hydrocarbons that evaporate from about 100 degrees F to 270 degrees F. The higher evaporation temperature means that it takes longer for vaporization to take place as well needing a higher temperature to do so. At wide open throttle, and as RPM increases, there is increasingly little time for evaporation to take place. The 100 octane gasoline will vaporize more readily, and convert more chemical energy to mechanical energy than the 92/93 octane fuel, and therefore the 100 octane will make more power and improve vehicle performance when compared to the 92/93 octane gasoline (with or without octane improvers).Putting an octane improver into 92/93 octane gasoline does not change that high temperature for evaporation. Plus, there is no guarantee as to what octane you will end up with even if you follow the manufacturer's suggested dose. Unfortunately, the octane improver industry is not regulated like the retail gasoline business, and they can make bold claims without having to back them up. Octane boosters are addressed in a tech bulletin on Rockett Brand's website
