Couple of questions I don't see being addressed:

1. If regular mogas is 80/87, like it says on the pump, and you take
out the octane booster (alcohol), what is the octane rating of the
remaining gas?

2. How do mid-grade and high-test achieve their octane ratings? Do
they just add more alcohol?

What I'm asking is, if your engine is rated for 80-octane, and you
reduce the octane rating below that by taking out the alcohol, is that
a good idea?

3. What is *in* that non-alcohol gas in Iowa now that boosts its
octane? TEL? MTBE? Nitroglycerine?
