| More than 6 months not being moved in the tank, (CHANGE). 4 months or less run it!! If its a 4 stroke you can go about a year with a good quality, 89 oct or higher fuel. I had my 25 mariner for over 10 years and never winterized the fuel. But I made sure that I ran it out of the carbs before I stored it. It never failed to start in the Spring. If you dont want to run it as is, get a 6 gal tank and remix with a new batch 50/50. Shouldnt take long to burn it up. But I dont think you will have problems if it set less than 5 months. I have had engine generators set for 2 years with fuel in the tank and they never failed to start. | |
