The Chevrolet Colorado's fuel tank size varies across model years, making it difficult to provide an exact figure without specific details. However, based on the information provided, I'll do my best to give you a comprehensive yet concise summary. From 2004 to 2012, the Colorado had a 19.0 gallon fuel tank. This was upgraded to a 21.0 gallon tank in 2015, which remains the same up to the current 2021 model year. With a decent fuel economy of around 20mpg in the city and 30mpg on the highway, the Colorado's tank capacity is more than sufficient for long trips, surpassing other trucks with similar power.
The 2020 Chevy Colorado can hold up to 21 gallons of fuel in its tank.
The maximum capacity is 21 gallons for the gas tank in a Colorado, but diesel fuel tanks can hold more. It would be beneficial to have a larger gas tank, around 26-34 gallons, especially for long trips or when towing a trailer in areas with limited gas stations nearby. It is hoped that the manufacturer or aftermarket companies will offer the option to increase the gas tank capacity for the Colorado model.
I successfully poured 18 gallons into the container.
William Ferdon mentioned that he encountered a similar problem. After the automatic click-off, he continued to add gas slowly and put in a total of 23 gallons (with a few gallons already in the tank). This observation suggests that the tank may have a greater capacity than the stated 21 gallons. Initially, he suspected it was a gas pump issue as the gas gauge did not change despite adding more fuel, but after driving for several hundred miles without the gauge moving from full, he found it peculiar.
In 2018, a Colorado vehicle with a tank capacity of 28-30 gallons was filled with 21 gallons initially, but it was able to hold 30 gallons in total. To achieve this, the last 9 gallons had to be added slowly after the pump initially clicked off.
Yes, the diesel tank has a capacity of 21 gallons and can be upgraded to hold even more fuel. It would be great if they could offer a similar upgrade for the gas tank to increase its capacity.
