I've been frustrated with my truck's DEF system for some time now...It seems that DEF fluid is wildly unstable (something they really don't tell you when buying a truck) and as a result, I've experienced my share of DEF system failures. Even when adding DEF fluid as recommended, the volatility of DEF fluid creates a seemingly perfect environment for DEF systems to fail when driving a diesel-powered truck like mine. A friend suggested I try using NuDEF...I was skeptical but figured I had nothing to lose. The dreaded DEF system light had returned again and before making yet another trip to my local dealership to once again be charged a fortune for a repair, I tried it. Wow! After mixing in NuDEF with my DEF fluid and driving for a short period of time, my DEF system light went off and my truck seemed to be a bit...happier! It's now been a few weeks and I have yet to see the DEF system light return and my truck has been performing perfectly. Thanks, NuDEF...You DEFinitely (see what I did there) have a customer for life!

Great Great product! Cleared up my Def system my check engine light is off now!! Ive also noticed I’m getting better milage on my truck! I heard about this stuff through a friend who works w diesel engines, who told me to try it. It turns out my def must have started to crystalize in the lines or not flow properly triggering all sorts of codes.. and this did the trick. Saved me major bucks on new pumps and limes. Btw a bottle goes a long way and truly a must for any def system!

Regen interval increased with this product. Not sure about helping with deposit build up bc I've not pull the def injector to look. Would be nice if the company had some hard 3rd party testing we could evaluate.

It is easy to squirt into the DEF tubing and i then flushed it down with some DEF fluid. I notice nothing different in the car running so i do not know if it works or not

Too soon to evaluate, but like the measured scale on the side.
