If Chevron is in your area, I'd suggest you use it. Car companies in Detroit buy it by the tanker truck full from Kentucky because it ain't marketed in Michigan (info from Chevron's web site).
And Chevron's web site has some really good information on gasoline, octane, etc. Their web site's link is below.
