Keep in mind there is no single blend of gas sold throughout the country. Different regions have different blends for pollution, emissions and other local controls. Rural areas might have some of that and might not. Different climates affect how the gas degrades too. While ethanol gets the blame, it’s often ethanol and the other additives that are the cause the issues. They all break down or evaporate at different rates but are in the fuel for different purposes, clean injectors, limit deposits, lube parts, etc.
