DEF is a 32.5% urea solution that is injected into the exhaust to break down harmful nitrogen oxides into harmless nitrogen and water, helping vehicles meet emissions standards. You typically need to refill the DEF tank before it runs empty to avoid warning lights, reduced power, or a no-start condition. This container size is common for top-offs and smaller fleets, and any DEF meeting ISO 22241 is functionally identical.
