To all that run old premixed fuel in their vehicles...I've been running leftove old outboard fuel in my pickup for years...generally about 5 gallons to 15 gallons of fresh gas, and never more than a couple of months old on the premix, and never more than a couple of times a year. Well it jumped up and bit me, I got a stuck ring on one of the pistons of the big Ford V8. An auto mechanic thought it was broken but I ran some Sea Foam down the carb and freed it up but it could have been worse. Here's my suggestion to all who follow this practice, I would recommend that you mix some decarb juice with the premix to avoid any problems with the carbon buildup you might get...just a Thought
