I was just wondering (Fuel Question)

Me being an East Coast person would somebody please explain the gas ratings in the Mid West. I'm refering to the regular (87 Octane) vs the Plus (89 Octane)It blows my mind pulling up to the pumps and seeing the Plus grade 10 or 15 cents cheaper than regular. I know its because the Plus has more Ethanol(% anyone?) The second thing that peaks my curiosity is who uses Plus? My owners manual on my V-10 engine and on my 4 cyl chevy engine state 87 octane is to be used.
Is anybody using this in a V-10 and if so do you see any consequences

    Alot of the small,but high H.P. engines require the mid grade. My SIL has to use it in her BMW and the neighbor needs it for his Nissan. Where do you find 89 cheaper than 87? If it's cheaper, I may switch for my two gas powered vehicles. (TV is diesel)

    Check out wikipedia and type octane rating.

    It's great... Much better of an answer than I could give you :)
