Excellent post, and thank you for your detail
Some questions:
- You mentioned that MTBE additive increases the octane rating, but also that octane rating is purely the ratio or percentace of octane in the 100% mixture? Are you saying that MTBE PLUS the octane percentage add up within the 100%?
- I read somewhere that higher octane also leads to slightly higher fuel mileage. From the previous essay, we can rule out higher energy content, so there may be something about the efficiency of combustion? Anybody have comments on that?
- I guess when I see a "110 Octane Racing Fuel" that it is a ploy, since apparently octane rating peaks at 100. Is that right?
Thanks very much
