I'm not sure exactly what you are wanting to know so I will just assume that you are asking about the gas mileage. A 2007 Chevrolet Silverado gets 19 miles per gallon (highway) and gets 15 miles per gallon (city).
Chevrolet made many versions of their S10 in 2001. The average gas mileage for their S10, V6 pickups is between 13 miles per gallon city and 19 miles per gallon highway.
18 miles per gal.
The city mileage is about 19 mpg, the highway mileage is about 26 mpg. The average is about 22 mpg.
The fuel mileage, on a 1993 Chevrolet 1500 pickup truck, is stated as; 18 miles per gallon on the highway and 13 miles per gallon in the city. The mileage ratings vary according to the size of the tires and transmission.
At 50,000 miles maximum is my recommendation. Your owner's manual may have a different mileage listed.
The car should last you just about 150,000 miles without to many problems...
It would have to be perfectly tuned to get more than 13 miles to the gallon.
