As most of you know, DEF fluid is highly sensitive. It has to be stored at a certain temperature and it has an expiration date. Not knowing these facts, I called my local Jeep dealer Service department and they said I could buy DE from any auto parts store. I took their word for it since the manual doesn't say anything about using only MOPAWR brand fluid.

I filled the tank about halftone and it ran about 500 miles without issue. I bought more PEAK brand DEF filling the tank about 3/4 full. After about a week, I got an error saying "Bad DEF Fluid, see dealer immediately." Apparently if the fluid is bad, the car won't restart after a couple hundred miles.

Turns out the message was misleading and there was nothing wrong. The car just had to be driven for about 50 miles to cycle through and clear the message. Given the sensitivity of the fluid and the potential thousands in dollars in damages bad fluid can cause, I'll be going to the dealer to have them top it off. It's just not worth saving $100 or whatever and take the chance of causing a larger proble,m.

I hope that helps.
