How big is a Chevy S10 gas tank?
A typical Chevy S10 gas tank holds about 18 gallons (68 liters), though exact capacity varies by year, engine, and drivetrain.
The question spans two generations of the S10 and several configuration options, which means the official capacity isn’t identical across every model. Fuel-tank size is influenced by production year, engine choice, whether the truck is 2WD or 4WD, and cab/bed configuration, as well as any optional fuel-tuel or aftermarket tanks.
Tank sizes across the S10 generations
To illustrate common baselines, here are the typical ranges reported for the two main production periods of the S10/Sonoma lineup.
- Gen 1 S-10/Sonoma (1982–1993): typically about 15–18 gallons (57–68 L).
- Gen 2 S-10/Sonoma (1994–2004): typically about 18–19 gallons (68–72 L).
In practice, the exact figure for a given truck can vary slightly due to year-by-year changes, trim levels, and optional equipment. For a precise number, consult the vehicle’s manual or GM’s official service data for your specific year and model.
By configuration and options
Gen 1 specifics
Early S10/Sonoma pickups feature a range that generally sits in the 15–18 gallon band, with minor deviations depending on cab and bed choices.
Gen 2 specifics
Later-generation S10/Sonoma models settled more consistently around the 18–19 gallon mark, though small variations can occur between trims and production weeks.
How to verify your exact tank capacity
When precision matters—for instance, for trip planning or fuel economy calculations—use these steps to confirm your exact capacity.
- Check the owner's manual or GM service literature for your specific year/model.
- Inspect the fuel capacity label, which is often located near the fuel filler door or on the door jamb data plate.
- Ask a Chevrolet/GMC dealer or access GM's online service data database using your VIN to pull the exact specification.
- If you attempt a DIY check, fill from empty to full and record the gallons dispensed; this is an approximation and can be affected by pump accuracy and residual fuel.
Overall, official specifications trump approximations, and minor variations are normal across production lots and aftermarket changes.
Summary
The Chevy S10’s fuel-tank capacity is typically around 18 gallons, with early models tending toward 15–18 gallons and later models closer to 18–19 gallons. Exact capacity depends on year, engine, drivetrain, and configuration. For the most accurate figure, consult the owner's manual or GM’s service data for your specific truck.
