I don't know which brand I've been using but since I use the stuff for
the 2 gallon tank of a push mower I don't use much of it so I've
probably had the same can at least 5 or 6 years. It's stored in my
garage which maybe gets a little below freezing in the winter and
perhaps 80 on a very hot summer day.
