Default Old DEF

Well, I finally got around to dumping the 3 year old DEF that I had stored in my basement, and it was absolutely CLEAR. Does that mean it was still good, even after 3 years?

I had put it out near the street with a free sign on it and age of DEF, but nobody fell for it after 3 days. Even said it appeared clear through the bottle.

It was likely OK, but it is not worth the trouble if it wasn't.

Isn't it normally clear? That's why I try to refill from truck stops. No leftovers.

It is just purified pee. Dump it down the toilet.

I think they run it through a very large kidney.

HaHa
Should have put it on the curb with a price tag...
It would have been taken (stolen) right away.

My understanding is that it is a bit more than pee. If you have any traces of scale or stains in your toilet bowl maybe dump it in and let it sit overnight. It may help to get rid of those stains vs dumping a chemical into the sewer system for no reason.

Next time you might want to save the spout since they fit on many other bottles.
