Worked on BMW def cleaner
My 2014 BMW had wrong Dec fluid sign in the dash board. Even though I have been using the same fluid for years. I had 50 miles left on it before car was going to shut off. I put this fluid in it half of this container I let it sit for 6 hours. After that I cranked the car the the light in the dashboard went away. It has worked for me I love it

Be aware.
Added to full tank, drove about 500 miles all seemed normal. Then notice the DEF gauge went from about 1/2 to 3/4 full... stayed that way for a while. Then received notice of 589 miles left, but was showing 3/4 full (not enough miles compared to the amount in tank), about 50 miles later all of a sudden received dash notice DEF is empty!! Looked at gauge - 0 DEF. About 20 miles later DEF gauge went back to 1/2. Made it to fuel stop... took about 2.5 gallons.. which is normal at 1/2 tank. Very stressful drive. Not sure if this was working or screwing things up. Hopefully no perm damage. Will not use again.....

continuous DEF flow
I have a 2017 Volvo VN daycab. DEF was not being used up by truck. Had no light on dash. Filter soot level was increasing and within a couple of days it was almost full.Went the cheapest, fastest way to find a solution. So I changed my DEF tank filter and simply added this solution to DEF tank, really easy. Seemed to have broken up whatever was clogging the system and now my DEF is being used up and back to regular usage.
