Diesel fuel treatments?

[Dan B.]

I have a drum of diesel fuel that's been in a garage for a couple months. With the winter getting toward the shorter end, I will not use all of this fuel in my heaters before the warmer weather is here. I've heard there is a biological "thing" that can grow in stored diesel and it should be treated with a "biocide" agent. I've read of several types but do not recognize the brands and never noticed them around here. I use Sta-Bil is all my gas cans and vehicles that are stored for more than a couple months. I'm not sure if this would do well in diesel or if something else is better.

Does anyone here use a diesel additive to prolong it's useable life?

If the diesel is stored in a relatively cool place sometimes its not a big issue. There tends to be more water in warm diesel. For only 55 gal. drum you should be ok with a diesel treatment with water remover. We have a 1000 gal. tank on the farm that needs routine maintenance and drained a lot. It doesn't help that off road fuel is garbage fuel. If you are worried about it next year I would weld a small drain valve on your tank.
