Review on ๐Ÿ“Š DEF Refractometer: Accurate Measurement of Diesel Exhaust Fluid Concentration in Diesel Engines by Anthony Gutierrez

Revainrating 5 out of 5

Easy to use and good price.

Using bad DEF in your diesel car can be a very expensive and inconvenient problem. This is a very inexpensive way to avoid all the problems associated with a bad DEF. I was very surprised how easy it is to use. Worth the price.

Pros
  • Ideal for a small home
Cons
  • No paint required
