17yrOldStanger said:im with you on that one. especially the way prices on gas are. In my area, the prices are considered "cheap". the low test is ONLY $1.73. that to me is not cheap at all.
How do I make less power when I run 93 compared to when I run 87 octane?
Mrgreen94gt said:If you aren't detonating, you'll only make less power with higher octane.
Due to it being more resistant to ignition as compared to lower octane. The 87 burns more completly and easily. The difference in power could only be slight, but enough I can notice it. Just doesn't feel as snappy on higher octane.
swingline said:So your opinion is based on a car with a completely stock ignition system?
Mrgreen94gt said:It would apply to any car or ignition setup, so long as there is no detonation. However, in many cases, boost or high compression make detonation nearly unavoidable without higher octane levels.
There have been some pretty lengthy debates in the past over the value of octane, I think most have been over at the Corral. Those threads have more technical info than I can provide.
