* Driving style: Aggressive acceleration and high speeds drastically reduce fuel economy. Gentle acceleration and maintaining a consistent speed will improve it.
* Vehicle condition: A well-maintained engine and properly tuned carburetor will perform better than a neglected one. Tire pressure also plays a significant role.
* Terrain: Driving in hilly or mountainous areas will reduce fuel economy compared to flat terrain.
* Vehicle weight: Additional weight in the car will decrease mileage.
Considering all this, expect 8-12 miles per gallon (mpg) in typical driving conditions. You might see slightly better mileage on the highway at a constant speed and worse mileage in city driving. Getting close to 15 mpg would be considered very good for this car. Anything significantly below 8 mpg suggests a serious mechanical problem.
