Chevrolet Silverado 1500 Fuel Economy: Pros
Year Body/Powertrain Comment
2008 4dr Extended Cab 6.5ft bed 315-hp 5.3L V8 4-sp automatic RWD I have the 1500 ext cab 2wd model that includes the 5.3 l v-8 with management. The truck gets 26 mpg on the highway! The average for the truck with over 6000 miles city/highway is now 20.6!
2007 4dr Crew Cab 5.5ft bed 315-hp 5.3L V8 4-sp automatic 4WD w/low range Best in its class
2007 4dr Crew Cab 5.5ft bed 315-hp 5.3L V8 4-sp automatic 4WD w/low range For full size truck with V8 I get 17-18 mpg in mixed driving.
2006 4dr Crew Cab 5.5ft bed 295-hp 5.3L V8 4-sp automatic 4WD w/low range With the specific gears I have in my truck, I get 20+ MPG on the highway...and I have a crew cab truck. City mileage is right in-line with the EPA of 14, but it is no worse than the others.
2006 4dr Extended Cab 6.5ft bed 295-hp 5.3L V8 4-sp automatic RWD The 5.3L gets an impressive 20mpg on the freeway and with a tonneau, about 21. Mixed driving is about 15-17mpg and purely city driving nets between 14-16mpg. Towing economy is not bad at about 12-13mpg with a light load and 9-11mpg with a heavy load.
2006 4dr Crew Cab 5.5ft bed 295-hp 5.3L V8 4-sp automatic RWD Good for a pickup truck.

2007 4dr Crew Cab 5.5ft bed 315-hp 5.3L V8 4-sp automatic 4WD w/low range Highway mileage could be beter.
2004 4dr Crew Cab 5.5ft bed 345-hp 6.0L V8 4-sp automatic AWD Big engine sucks gas - 8mpg on tests
2004 4dr Crew Cab 5.5ft bed 295-hp 5.3L V8 4-sp automatic 4WD, part-time w/low range Granted this is a truck but I did not like the fact that I was getting 14 mpg when the price of fuel was skyrocketing. This was never a good choice for fuel mileage.
