You're more likely to find 30-gallon tanks in:
* Larger SUVs and Trucks: These vehicles often require more fuel to travel longer distances and carry heavier loads.
* Certain Full-Size Sedans (less common now): Older models, or some luxury models, might have had this capacity.
To find out if a *specific* vehicle has a 30-gallon tank, you'll need to:
* Check the owner's manual: This is the most reliable source.
* Look at the vehicle's specifications online: Websites like the manufacturer's site, Edmunds, Kelley Blue Book, or others often list this information.
* Consult a fuel efficiency website: These sites sometimes provide fuel tank capacity data.
Keep in mind that even within the same model year and trim, there can be slight variations. Always check the specific vehicle's documentation.
