In Ohio, the county auditors want to be able to check gas stations for more than just dispensing the proper quantity of fuel, specifically they want to be able to test "quality". In the stories I saw about this though, it was for checking for water, contaminants, etc, not octane. Is water, "dirt", etc a problem ? It could be but I stick to high-volume stations and avoid the shady-looking Marathons, Valeros, and so on (ironically, supposedly "Top Tier" stations).
