Gas prices used to be only 4-5% difference between grades, but 60% increase from regular to premium is ridiculous.
So what did I do? I filled up with a blend of 50% premium 93 with 50% regular 87, and effectively paid $2.44 for a mid-grade blend that was cheaper than the pump mid-grade. I won't say that it's 90 octane, but I will say that it's at least as good as the 89 priced at $2.66.
Here in St. Louis, very few stations sell 89 octane, and 93 octane is ~$0.30 more than 87. What part of Michigan you live in?
What car do you have that needs premium? Most cars on the road do not require premium and actually running premium at best is a waste of money.
There have been 3 grades of gasoline at every station I've ever seen in Michigan, so where I live doesn't really matter.
I run premium in my Camaro in hot weather, and mid-grade in cold. Although since the car has aged, it seems to require premium more than it used to.
