Different octanes have different burn rates. If I remember correctly, lower octanes burn faster than the higher octanes.
I run 87 in my 998 duc, it seems that it runs better on the low octane than it does on 93. of course for racing higher octanes produce more power under flat out conditions.:poke:
A few charts for unleaded fuels....All very much an average. One might be wrong, it is the internet. But all of them?
