I HAVE ABOUT 10 GALLONS OF THIS MIXTURE, STILL IN MY BOAT FOR ABOUT A YEAR AND A HALF NOW (MAYBE LONGER). HAVEN'T RIDDEN THE BOAT AT ALL THIS SUMMER, SO NOT SURE HOW TO WINTERIZE AT THIS POINT.
You are pushing your luck with gas that old, will be 2 yrs old by spring.<br /><br />I've used it over 2 years old, but not advised. Some guys have trouble with 6 month old gas. <br /><br />I would run it thru my car, a gallon or two in each tank. Or use it in the snowblower, weed trimmer, lawnmower, etc. Use it in anything that won't leave you stranded somewhere.
