* Engine size: The S10 came with several engine options (4-cylinder, V6). A 4-cylinder will generally get better gas mileage than a V6.
* Transmission: Automatic transmissions typically get slightly lower gas mileage than manuals.
* Driving habits: Aggressive driving, frequent acceleration and braking, and excessive idling all reduce fuel economy.
* Vehicle condition: Proper maintenance (tire pressure, tune-ups, etc.) impacts mileage.
* Payload and towing: Hauling heavy loads significantly reduces fuel economy.
Therefore, there's no single answer. However, you can expect a range:
* 4-cylinder: Expect somewhere in the range of 18-25 mpg combined (city and highway driving), possibly a bit higher on the highway.
* V6: Expect somewhere in the range of 15-22 mpg combined, with highway mileage being somewhat better.
To get a more precise estimate for a specific 1995 Chevy S10, you should consult the owner's manual (if available) or look up EPA fuel economy estimates for that specific year, engine, and transmission configuration online (sites like fueleconomy.gov may have some data, though it might not be as detailed for older vehicles).
