Impossible to say.
There's the factory rated MPG, but that's assuming a 100% perfectly healthy engine, and perfect road conditions, and a controlled environment.
Basically, what NO ONE will ever encounter.
So, in a real world, mpg is based on how you drive, health of engine, weather, health of transmission, type of tires, and about 100 other factors. If we lined up 10 1993 Camaros, we would get 10 different results.
Make a chart, showing your mpg over time. if it is in fact going down...take your car in for a tune up, and look for problem areas. |
