Default Re: What Octane Do You Use?

This topic has been discussed several times before. I use to think higher octane better power. Higher octane is ment for higher compression. To better explain you want two things to occur in your cylinder; the detonation point and spark point to match. This gives you a complete burn. The higher the octane the higher the detonation point. Most of these small engines are low compression so that their easy to crank. From all the research I've done compression below 9.1:1 will run best on 87 octane.
