octane boosters

RE: octane boosters
using a fuel with a higher octane rating than the vehicle requires sends unburned fuel into the emissions system and catalytic converter. This puts unecessary stress on the emissions system. For some vehicles, a rotten egg smell coming from the tailpipe signals use of too-high octane gas.
Burning too high of octane not only empties your wallet quicker, but the gasoline will burn too late.
... it makes sense. the higher the octane the slower it takes for the fuel to burn completley. if it can't be burned all the way then it's wasted and can decrease performance

RE: octane boosters
I once put 87 octane in my tank and I could tell it ran like crap. Thats before I upped the timing. Once I finished the tank I filled up with 91 and it ran like it was supposed to. And to explain the accident, I was at costco and they only had 87 and 91 no 89 and I thought it was 89 and 91 so I pushed the "89" later to go back and realize its 87.

RE: octane boosters
The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the least amount of compression before igniting.
