I have a question regarding octane.  I have a ULS which I know requires at least 91 octane.  I have 92 octane with 10% ethanol available and I have non ethanol mogas with 89 octane available.  I'd like to run non ethanol.  Is it OK to use an octane booster, or is it safer to just use the 10% ethanol acceptable octane?
