Hi, I'm new to this forum and was hoping I could find some expertise here.
I've got a '00 Silverado 5300 and I'm looking for ways I can improve my gas
mileage. Right now I'm getting around 15-16 with mostly highway driving.
I'm considering a high-flow air filter such as K&N or Fram Air Hog. Also,
would a cold-air intake help? I've seen some K&N's for about $250. Any
just ny thoughts BUT stay away from k & n
i HAD one on my 2000 z71 noticed i said HAD.
it did nothing for me, only reason i got it was i had ordered something
from summit, and they said on next order i would get a discount.
think i ended up paying like 15 for the filter, worse 15 bucks i ever
i was getting round 15-17 mpg in my z71 that was city driving too.
same engine 5.3 with the 3.73 gears in back.
now i have a 04 gmc sierra and am getting about 15-17 in town its a 4x4.
I had one on my 2000 silverado Z71 also with the 5.3 and 3.73 gears. I
have never seen 15 city driving. I had the K&N FIPK next generation
intake and still have a flowmaster cat back exhaust. Notice I also
said "had" about the K&N. I paid a ton of money for it (like $350) and
noticed no difference other than the noise. They do not filter as well
IMHO and not worth the money. Certainly sounds like you are going
faster, but I doubt there were any HP gains or increased fuel economy.
I get 12 in town and 14-15 on the highway. I believe the best way to
improve gas mileage is put a block of wood under the gas pedal!
You can drop your tailgate and gain about 1-1.5 mpg usually.
I once considered the Splitfire spark plugs but hesitate since I do not
know anyone that has tried them.
But alas, we're stuck with not great mileage. But I love the truck as
it is fun to drive and can haul a good bit of stuff without any trouble.
