It is easier for me to check the gas before I use in in any engines I have. I don’t have to rely on a station telling the truth about the Ethanol in the gas. If the tests show that mess, I will not use it and I will scratch that station off my list. [:0)
Keep in mind gasoline stations, especially discount (non-name brand) stations, do not always get their gasoline from the same source, especially if you are near a high population center that likely has multiple truck loading stations.
