Obviously there are varying factors that can change the milage between vehicles, including driver's habits, the vehicle's current state of repair (ie: has the vehicle been tuned up recently? Are the dashboard lights showing a SES light?), and drivetrain configuration (4wd, 2wd, Awd)but a reasonable breakdown for the 4.3 Vortec motors will be somewhere along the lines of this.... 2wd: 15-17 mpg City, 18-21 Highway 4wd/Awd (Awd only applies to the Olds Bravada for the '98 model year): 14-16 mpg City, 17-20 Highway
The estimated gas mileage for the 1982 K5 Chevy Blazer is 19 miles per gallon in the city. The gas mileage for this car on the highway is 26 mpg.
Depending on the differential gear ratio, anywhere from 17 to 19 mpg.
On the Vortec the computer does it all.
