DEF Storage

I currently carry the 2.5 gallon plastic container of DEF in the basement and change it out every other month. I would like to carry a 5 gallon container. Is it better to use a plastic or metal container? The right side tank causes a few issues every now and then. I'm open for all suggestions/opinions/advise.

I bought mine at Tractor Supply. It's a 5 gallon plastic kerosene container with pour spout, blue in color. Sure cuts down all the hassle with the passenger side DEF tank. I just fill it while fueling then add the container DEF to the DEF tank when we park for the night. The bulk DEF is half the price of the 2.5 gallon jugs.

I just bought two, 2.7 gallon plastic jugs made just for DEP storage. I bought them from a vendor who advertises here and has been very helpful responding to posts.

It might be easier to store two jugs that one 5 gallon jug.

Always use polyethylene containers for DEF. Metal containers (unless they are stainless steel or Titanium ) will corrode quickly and contaminate DEF with metallic ions that are very bad for your clean diesel's SCR system. Reusing retail jugs is certainly reasonable, but be careful with paper cap seals and make sure the jugs are well sealed after each fill.

Always rinse a new polyethylene container with distilled water or water run through a water purifier (Like Zero Water or Brita) to remove any contaminants that may be present. Avoid using tap water to rinse DEF equipment especially if it is known to be "hard" (minerals).
As Don points out, we provide purpose built and cleaned jugs for storing reserve DEF on your vehicle. They come with a nice flexible spout, long-life polyethylene seals, and are pre-cleaned for your convenience. They also have proper labeling to avoid confusion about what is in the jug.
A 5 gallon jug full of DEF weighs over 50 pounds !!! As Toby Keith says, "I'm not as good as I once was", so we offer jugs in 2.7 gallon capacity for easier handling.
Great questions on DEF, and as always, please consider us a resource on all subjects related to DEF.

I just want to let you know that DEF will freeze and has a shelf life of about two years. Plastic or stainless steel containers, fittings only for DEF fluid.

How much DEF does your unit use that you need to carry 5 gal. ? How many miles per gal. of DEF do you get?

Almost every truck stop has DEF. And your unit should tell you when to add - then you may have 100 plus miles to go before you are in trouble. Why carry it with you at all?
