I checked the websites FAQ. Basically the question is this. I'm gonna have a vehicle down for a little while. I already added the dose of 5 gal/1 oz Stabil. The website did not mention anything about this dosage. The website just mentions that their X size bottle treats this many gallons. Should I just of went for the heavier dose? The tank is basically filled right now. Should I just dump the rest of the bottle in there to be safe? I believe I bought the 8oz bottle which treats up to 20 gallons.
