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...

The mid-grade is about 99% marketing. If there is a car out there that the manufacturer says that 89 octane should be used in, I don't know of it.
The cars, that I know about, have one of the following recommendations:
1. Regular (87 octane)
2. Premium (usually 91 or 92 octane)
3. A few OK regular but say that max power comes with premium. These are cars with sophisticated knock sensors and computer programming.
If your manual says that regular gas is recommended/required, that's all you need-----------------unless your car's tune has deteriorated to the point that it is pinging. Than 89 octane might be a short-term solution, but your engine needs some attention.
