What percent should DEF quality be?
32.5%
The ideal, or target reading is 32.5%. If under, more DEF con- centration is needed. If over, the urea concentration is too high. In reality, most DEF purchases will consist of premixed containers.
How much does a gallon of diesel exhaust fluid weigh?
about 9 lbs per gallon
DEF weighs about 9 lbs per gallon.
How is DEF quality measured?
Ultrasound waves are used in Diesel Exhaust Fluid (DEF) Quality Sensors, also known as Fluid Property Sensors, to detect the condition of DEF in a truck’s tank.
Is there a difference in DEF quality?
Engines with SCR are specifically programmed for optimal performance at this ratio, which is why it is important to make sure you get a quality brand of DEF that meets ISO specifications. There is one operational difference to note: Like any water-based fluid, DEF expands when it is frozen (by approximately 7 percent).
How do you check DEF fluid quality?
Field Testing
- Visually inspect DEF for color and clarity.
- Do a “smell test”.
- Inspect exhaust piping and DEF injectors for presence of crystallization.
- Use a handheld DEF refractometer to measure the concentration specifications of the fluid to ensure 32.5% of the fluid is urea.
How much does 2.5 gallons of BlueDEF weigh?

What does poor quality DEF fluid mean?
The Exhaust Fluid Quality Poor DIC message notifies the customer that the ECM has detected a drop in the SCR NOx reduction efficiency. This PI is to assist with vehicles that have difficulty completing the DEF (diesel exhaust fluid) quality test and/or clearing the Exhaust Fluid Quality Poor Message.
How do you know if your DEF fluid is bad?
The easiest way to spot bad DEF is by looking at it. DEF is naturally clear, so if the solution looks cloudy or colored in any way, it’s probable that it’s old or has been contaminated.
What is the best DEF fluid?
The best diesel exhaust fluid meets the Environmental Protection Agency’s standards and is free from impurities. Valvoline’s Premium Blue Diesel Exhaust Fluid is a top choice because it is compatible with all selective catalytic reduction systems and meets the EPA’s near-zero nitrogen oxide emissions levels standard.
Does quality of DEF fluid matter?
The quality of the DEF going into your vehicle is as important as the quality of the engine oils or fuels used in your vehicles. Use of API-licensed Diesel Exhaust Fluid will ensure that the DEF meets the high standards required by engine and vehicle manufacturers.
