Collective,

All my life I have heard that aviation fuel has additives that make it 
unsuitable for automotive use.  Is it only that you carb won't ice at 20,000 
ft or is there more to it than that.  I have been told that you should add 1 
oz of Marvel Mystery Oil to each gallon of aviation gas that you use.  I 
have also been told to mix it 1/2 and 1/2 with regular unleaded 91 oct. 
With aviation gas at $5.00 and race fuel at $10.00 it makes a difference to 
me for a higher compression engine.

Thanks in advance to the collective,
jerry
