I've got to service some gas equipment...a pressure washer and a generator. It's been over a year since I've used them. I used Sta-Bil the last time (I think), as I have one large opened bottle about 1/2 full, and another one unopened.
The unopened one looks pretty dark, and I was wondering if it's still good. Can't find a date on the bottle, and I can't remember when I bought either bottle. The directions say it can be used for up to two years after opening. What are the thoughts on how effective they can be.
