seems like stupid question, but Topeka sure as heck didn't have any 93.

QUOTE (00 SS @ Dec 14 2005, 11:26) Maybe you guys can help me out with something. It seems to me that if you use too much octane, you can actually reduce your power output. Octane makes the fuel burn slower, so if you don't have the compression or the timing to take advantage of it, it can hurt power right? BTW, absolut atmosheric pressure in Denver is 12.6 to 12.8 psi depending on the weather. I believe that higher octane makes fuel more resistant to ignition (like detonation), but not slower to burn. Fuel contains the same amount of energy per gallon regardless of octane. It's harder to light off, but burns at virtually the same speed. |
