A 1993 GMC Sonoma, equipped with 2 Wheel drive, a 5 Speed Manual Transmission and the 4.3 Liter Vortec V6 would get a City Mileage of 15 MPG. The same configuration would achieve a Highway mileage of 22 MPG, for an overall combined Mileage of 17 MPG. Expect 3-4 MPG better on the 4cyl equipped models.
