is there any truth to the statement that using a higher octane gasoline will

supreme 92 octane and in our area the price difference appears to be about
between regular and supreme.

and just what do you think Octane rating a measure of?

And good anti-knock properties ( higher octane ) allow the ignition to be
advanced which *may* improve engine efficiency. It pretty much invariably
