Almost hate to do it but it will probably start going bad if I don't use it .
It won't go bad. I started up one of my unused diesel trucks last year that I hadn't run in 11 years. It ran fine. Same goes for several of my Farmall tractors that have five year old fuel.
Save it and sell it to your friends with diesel. When the upcoming fuel squeeze happens, the govt will allow red road fuel just as they did following Katrina.
I have 4000 gallons of heating oil in storage. It is all reclaimed fuel from home owners who have switched to gas. I'll be able to drive 60,000 miles without going to a diesel stop.
In light of your signature, you may also want to save it to make IED's to plant along your driveway. Just mix it with fertilizer and set up a "fire control center" behind the picture window in your livingroom.
