Imagine my surprise to learn that exhaust fluid was real lol
Nissan named their donut style exhaust gaskets "bearings" so exhaust bearings do exist too.
What does it do?
It's used to condition the exhaust from diesel engines DEF
Huh, interesting. I wouldn't have thought that adding a nitrogen compound to the exhaust would reduce the amount of nitrogen oxides, but I guess urea is a good reducing agent.
Reduces harmful emissions from a diesel motor. Most new diesel trucks and cars have an exhaust fluid reservoir that needs to be kept full.
