The gas tank on the 2006 Toyota Tacoma is 21.0 gallons (about 79.5 liters).
This article explains the official tank size, whether it varies by cab or drivetrain, and what that means for range and everyday use.
Tank capacity for the 2006 Tacoma
Before listing the figure, note that Toyota used a standard tank size for most 2006 Tacomas across different configurations. The official capacity is:
- 21.0 gallons (79.5 liters).
Across Common configurations — Regular/Access/Double Cab and 2WD/4WD models — the fuel tank size is generally the same. For absolute certainty on a specific vehicle, check the owner's manual or a VIN-based spec sheet, as regional variations or aftermarket alterations are possible.
Estimated driving range on a full tank
Because actual range depends on engine choice and driving habits, here is a rough guide based on typical fuel economy for the 2006 Tacoma lineup:
- 2.7L four-cylinder models (roughly in the low to mid-20s mpg combined) would yield about 420 miles or more per tank under favorable conditions.
- 3.4L V6 models (roughly in the high teens to low 20s mpg combined) would yield roughly 340–450 miles per tank, depending on driving conditions.
Real-world range varies with load, terrain, maintenance, and driving style. To estimate your own range, multiply the tank capacity by your observed miles-per-gallon under similar conditions.
Summary
In short, the 2006 Toyota Tacoma uses a single standard fuel tank of 21.0 gallons (79.5 liters), shared across most trims and configurations. Expect a few hundred miles of driving range per tank, with exact numbers depending on engine choice and driving conditions.
