Length of time diesel fuel stays good in tank

Assuming the diesel fuel was treated with Stabil and Biocide last fall how long would it be safe to burn since the pandemic has cut short travel plans all this summer? For years have done this in November and started travel in March or April next year, but not this year.
And what do you do with a tank full of diesel that shouldn't be run through the engine? Never had this problem in 30+ years of RVing.
  • Particularly if the tank is full (to minimize condensation) you should be just fine with the Biocide you added.

    I let my diesel pickup ( f250 7.3l navistar) sit for 2 years. It fired right up and I had no issues. Fuel was not treated in anyway prior to letting it sit. This is in Florida so plenty of heat and humidity.
  • your going to get all kinds of answers , heres mine , just let it alone. construction crews ,farmers etc let some equipt set for years m, little prime and start them up. me I,d drive the rv about twenty miles every month or so . just to keep things lubed up.
