I just bought a stihl weed eater and taming my small wild backyard is this years project. Really happy with the results but when I looked into storing the 2 gallon gas carrier i saw the answer is only in an external shed (which I don’t have) and that it goes bad in a week. Is this actually true? Do I need to drain my weed eater after each use and get gas each time if I’m just using it once a month?
