In 2002-2005 Chevys, does the small block V-8 get much better milage then the bigger V-8?

Does the smaller engine in the Silverado 1500 get enough better milage to justify or should I get a bigger V-8 and drive conservatively?In 2002-2005 Chevys, does the small block V-8 get much better milage then the bigger V-8?

4.8 vs 5.3 my bro has a 2000chevy silveraod with the 5.3 he gets right at 17-18 round town and 27 on the hwy 4.8 gets a lil better gas milage but ya trade off how much weight ya can tow if ya have to tow something a friend of bros has a 2000 f150 with the 5.4 ad gets bout 20 round town and 28 on the hwy running bout 70 hope this helps ya out
The difference between the 4.8 and 5.3 on the Silverado is only 1 mpg highway; city mileage is the same. The question is if having the bigger engine is worth paying the extra money for, if there is a price difference. And also 1 mpg highway with gas at $3 a gallon could mean a difference of $100 a year in gas, assuming 15,000 annual miles of driving. So there is that to consider as well. Driving conservatively probably won't make a difference because EPA highway mileage estimates are already based on driving at 55 mph, the most fuel-efficient speed possible. Actual mileage is always lower than the highway mileage because people go faster on the Interstate and do a lot of stop-and-go driving in the city. There is a Silverado "hybrid," but the improvement in the city mileage is pitiful at only 2 mpg, and the highway mileage is the same.In 2002-2005 Chevys, does the small block V-8 get much better milage then the bigger V-8?
about the same
they is very little difference.In 2002-2005 Chevys, does the small block V-8 get much better milage then the bigger V-8?
Not really. It has been my experience that a smaller engine has to work harder to move a large vehicle. This means that more gas is consumed.



Case-in-point: Had a 1978 Lincoln Continental Town-Car. It's big with a 460 CI engine. Ran great, respectable mileage.

Also had a 1979 Lincoln Continental Town Car with the 351 engine. The smaller motor couldn't really power that huge car well at all. Gas mileage was considerably lower. I'm sure that small (351) motor was worn out way before the 460.



Plus the larger motor gives you more pulling power and a higher resale value when you want to replace it.
