How many miles per gallon does a 1980 Porsche Carrera get?
The 911SC can be fairly economical on gas, depending on your driving habits and that the car is in good running order. Overall, you could probably expect to average in the low 20s (22-25mpg) for most driving conditions. You may see 30mpg on a long highway trip, or just under 20mpg with alot of city/traffic driving. If attending a track day, milage will be closer to 8-10mpg. Following that, if you drive in the above conditions extremely aggressive, you’ll see a little less (though the above numbers would likely include some spirited driving as you would expect to do in a Porsche). Likewise, engine problems or issues with the CIS injection will also have a negative effect on fuel economy.
