I asked someone in the oil business about mixing the octanes and told him about what I'd read in the thread here. This is his response...

Hi Mike,
You are reading a half truth. When gasoline is manufactured, it is regular gasoline with an octane rating of 87. Then octane processing is the final step where the mid/plus and high/premium octane are created.
There are truly different grades of gasoline because the burn rate in relation to the engine is critical. It allows first for clean, maximum burning in the cylinder to minimize pollution. It allows the engine to get maximum horse power and torque. If a lower grade gasoline is used that burns faster, it can possible cause damage to the valves over time, not to mention screwing up mpg ratings.
Now concerning the federal fines . . . not all states test gasoline. I live in Texas and it is not done here. However, states that do will find the gasoline in the wrong tanks and fine someone. I have never researched federal guidelines because this is an issue that is usually handled at the state level. I guess I need to look into that.

I'm back.
I was planning on alternating between 91 and 89 once my tank gets to half full. I'm not sure now.
