Depending on the year of your specific Chevrolet Colorado model, the capacity of diesel exhaust fluid may vary slightly, usually just under 5 gallons. Many owners typically add 2.5 gallons at a time, filling up as needed based on the gauge. It's recommended not to let the tank run completely empty, but it's not necessary to always keep it full either. The truck's mileage on a full tank can vary, with some drivers getting as few as 3,500 miles and others achieving over 5,000. If you're planning a long road trip, it's a good idea to have some extra fluid on hand. For everyday driving, topping off regularly should be sufficient.
What is the fuel capacity of the 2022 Chevy Colorado?
