Avgas and mogas are rated/tested by different methods and
standards.

| 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?
