## Customer Reviews

### ⭐⭐⭐⭐⭐ Extend the life of your DEF
*by S***D on March 20, 2025*

I was really happy to find this product. Living in Alaska, and the DEF being a concern with its 2 year life span, it doesn’t always get all used with our short travel season. It’s not a problem if I drive the Alaska Highway to the States, but that’s not always the case. My DEF freezes in its tank over winter but that’s no problem. Being able to extend the shelf life of DEF is a no brainer. If this product works as advertised I’ll be a Happy Camper. Although I haven’t had a chance to experience its attributes yet, I will this summer. Not driving to the States this summer through Canada but will be taking a tour around all of Alaska’s 800 miles of roads to use up some DEF and give this product a workout .

### ⭐⭐⭐⭐⭐ Good stuff
