The 2008 Honda Pilot has a gas tank capacity of 21 gallons (about 79 liters).
Official specification and what it means for the model year
Honda lists the 2008 Pilot with a 21.0 US-gallon (79.5 L) fuel tank. This capacity is consistent across the main trims and drivetrain options for that model year, including both front-wheel drive and all-wheel drive configurations equipped with the 3.5-liter V6 engine.
Driving range and fuel economy context
Knowing the tank size helps estimate range, but actual distance per tank depends on real-world fuel economy, which varies with driving style, city versus highway trips, and vehicle load. In typical mixed driving, pilots of this era show mpg in the teens to low 20s, so a full tank generally covers several hundred miles.
Practical takeaway
As a rule of thumb, expect roughly 350 to 450 miles per full tank under everyday use. For a more precise range, consider your own driving habits and consult the vehicle’s onboard fuel economy readouts or the owner's manual.
Summary
The 2008 Honda Pilot uses a 21-gallon gas tank (approximately 79.5 liters), a capacity that remains consistent across model trims for that year. Range per tank varies with driving conditions and efficiency, but the tank size provides a solid baseline for planning fills.
