2007 Chevrolet Silverado 1500 LT1 4dr Extended Cab 4WD 8 ft. LB (5.3L 8cyl 4A)
The truck does not get 16 and 20 mpg as stated . This fuel management engine is worse than my last Chevy. The truck makes a grinding or rubbing noise at between 40 and 45mph. GM says this is a exhaust noise. Dealership says they can muffle the noise a little. Paid $35 grand to listen to a noisy exhaust. Very disappointed in the truck. fales advertisement by GM on the gas mileage. Will purchase a Honda next time
