DEF Fluid Expiration & Storage

[Dallas2000]

I bought some Blu Def that had been sitting outside on a shelf in the sun. I had no idea it could go bad. Damn Walmart!

BLUEDEF HANDLING AND STORAGE The shelf life of DEF is directly related to the temperature at which it is stored. Storage temperature between 12º and 86º F are recommended to maintain optimal shelf life of up to two years. If BlueDEF freezes, its efficacy will not be effected upon thawing. To maintain the purity of DEF and not harm the SCR Catalyst System care must be taken regarding the material of construction for all items that come in contact with the DEF solution. Included from the ISO-22241-1 standards are the recommended and not recommended materials for contact with DEF.

Thanks for the reminder. I hate that part of being a diesel owner.
I don't think they use that type of system in Europe. Can anyone confirm that?

You will get a warning light on the dash when you are low.

Great info, glad I saw it, I was topping mine off at the truck stops but two possible problems with that:
1). contamination
2). over fill in winter and have a possible expansion problem.

I think I will just get the filler tube from Ford
