Tank Capacity by Drivetrain
FWD Equinox models carry approximately 14.8 gallons of fuel, while AWD models carry slightly more at approximately 15.6 gallons, reflecting minor packaging differences between the two drivetrain layouts.
Estimated Driving Range
At the current EPA-estimated 27 mpg combined for FWD models, a full 14.8-gallon tank works out to roughly 400 miles of combined-cycle range, while AWD models at 26 mpg combined and a 15.6-gallon tank land in a similar range, around 405 miles.
Tips for Maximizing Range
Keeping tires properly inflated, avoiding unnecessary idling, staying current on oil and air filter changes, and moderating aggressive acceleration all help you get closer to the higher end of your Equinox's realistic range on a full tank.
Quick Reference Table
| Drivetrain | Tank Capacity | Approx. Combined Range |
|---|---|---|
| FWD | ~14.8 gallons | ~400 miles |
| AWD | ~15.6 gallons | ~405 miles |
Frequently Asked Questions
Why does AWD have a bigger tank but similar mpg?
The larger tank on AWD models roughly offsets their slightly lower mpg rating, which is why the two drivetrains end up with a similar real-world range despite different tank sizes.
Does tank size vary by model year?
Tank capacity has been fairly consistent across recent Equinox generations, but always check your specific model year's owner's manual or window sticker to confirm.
What's the fuel type requirement?
The Equinox's gas engines run on regular unleaded fuel, with no need for premium under normal operating conditions.
How does the Equinox EV's "tank" compare?
The Equinox EV has no fuel tank at all — instead it uses a battery pack rated for up to 319 miles of range on FWD trims, an entirely different type of range calculation than a gas tank.
