Pretty much all gas stations in my area have the ethanol added. But every chance I got on the way to Alaska I would get the nothing added good stuff. The crack is small at this point, but the length of the right side. Could octane rating be an issue?

I ask because it takes more heat to ignite a higher octane fuel meaning it won't expand as much as the lower octane fuels less than 89 in the fuel tank. Does that make sence?
