I use a product called PRI-D (16 oz for 256 galls) for adding to my emergency gen set fuel tank. Its spoz to "keep" the diesel for years. Don't know how well it works but their claims are impressive. Got it from some "survivalists" site up in Montana.
BTW while I was a deckhand on a tug and we had to use fuel from a double bottom tank ( always kept full for ballast and seldom used). no one remembered how long it had been there but it was agreed, at least 12 years.
Those V 16 gimmeys kept running and I wish I would have been interested enough then to ask what the filters looked like. I have heard that the constant movement kept it from "stratifying or what ever it does to make it go "bad" So maybe all you have to do is shake it up new and then and of course, keep the water OUT..
I wonder if there is a dye on the market to counter the red dye?
