I run it through fine mesh strainer and mix it a little at a time to my lawn mower gas or to my old trucks gas tank.Done it for years no problem.
^^^^^THIS.
Pour it through some sort of strainer and mix it with the fuel of anything with a carburetor. EFI engines can get a little more finicky about that sort of thing but it never stopped me! One time, I straight up poured 2 gallons of old premix into an almost full tank in my pick up truck. The ratio was about 20 gallons of E-10 and 2 gallons of old, nasty premix. My truck (1999 Silverado) never knew the difference and that was 20k miles ago.
