But low-quality DEF can still cause problems. If a truck is running low-quality DEF, there are a number of issues that may occur, some of which could even void a vehicle’s warranty. This includes catalyst poisoning, deposits, and injector/filter clogging. Repairs can be very expensive and downtime may be extensive.
Why is DEF so expensive?
Prices for the diesel exhaust fluid that is a vital component of emissions systems on newer trucks are rising as costs for urea — a core DEF ingredient — have jumped. It’s certainly a noteworthy increase in price levels. But it’s all driven by urea prices.”
Can you mix different brands of Def fluid?
Registered. I’ve mixed different brand of DEF and never had an issue. Just make sure it meets the required specs.
What is a good DEF percentage?
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.
What percentage should def fluid be?
Diesel Exhaust Fluid is made up of 32.5% automotive grade urea and 67.5% ionized water. The concentration of the DEF must be 32.5% urea (+/- 0.7%).

Is diesel exhaust fluid dangerous?
Diesel Exhaust Fluid (DEF) is not toxic, harmful or dangerous. In fact, of all the fluids used in a truck, such as diesel, engine oil, brake fluid, antifreeze and windscreen wash, DEF is the least hazardous.
What is diesel exhaust fluid and how does it work?
How Diesel Exhaust Fluid Works: When injected into the exhaust stream with a specialized dosing module, BlueDEF’s water vaporizes, leaving ammonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor—making for cleaner emissions.
What year trucks require Def?
What Year Chevrolet and GMC Trucks Require DEF? In 2007, Duramax produced a 6.6L engine with new diesel particulate filter technology. However they didn’t start using DEF until 2010 in response to 2010 EPA regulations. In 2011 General Motors released the latest in its Duramax line, labeled the LML. This version introduced advanced emission controls, including diesel exhaust fluid injection.
