The standard gasoline fuel tank for most 2008 Chevy Silverado 1500 pickups is 26 gallons (about 98 liters).
In this model year, Chevrolet offered several gasoline engines — including the 4.3-liter V6, the 5.3-liter V8, and the 6.0-liter V8 — paired with different cab and bed configurations. Official specifications for the 2008 Silverado 1500 list a 26-gallon tank as the standard capacity across these configurations. The actual driving range from a full tank depends on the engine, drivetrain, payload, and driving conditions, but you can expect roughly 450–500 miles from a full tank with typical mixed driving in the more efficient setups, and somewhat less with the larger V8 engines under heavier use.
Configurations and how they relate to tank size
Although 26 gallons is the typical published capacity for the 2008 Silverado 1500, slight differences can occur due to cab style, bed length, or optional equipment. For precise figures for a specific vehicle, check the original window sticker or the owner's manual for that VIN.
Practical notes for owners and buyers
If you’re evaluating a used 2008 Silverado 1500, consider that tank condition, fuel pump health, and fuel gauge accuracy can affect real-world range. A tank that reads full after a partial fill may indicate issues with the sending unit or gauge calibration, so it’s worth testing with a full-to-empty fill and monitoring the miles driven per tank.
Summary
In short, the 2008 Chevy Silverado 1500’s gasoline fuel tank is typically 26 gallons (approximately 98 liters). This size applies to most common configurations from that year, with minor variations possible based on cab/bed setup and options. Real-world range will vary with engine choice and driving conditions.
