How many miles to the gallon can a 8 cylinder 1994 Chevy blazer get?

The gas mileage of a 1994 Chevy Blazer with an 8-cylinder engine varied quite a bit depending on several factors: the exact engine size (e.g., 4.3L, 5.7L, or even a 6.5L diesel), the vehicle's condition (tune-up, tire pressure, etc.), driving style (aggressive vs. conservative), and terrain.

However, you can generally expect 12-16 miles per gallon (mpg) in combined city/highway driving for a gasoline-powered 1994 Chevy Blazer V8. City driving would likely be on the lower end of that range, while highway driving might be closer to the higher end. A diesel version might achieve slightly better fuel economy. Keep in mind these are rough estimates; actual mileage could be higher or lower.
