| 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
ideas? Thanks.

I doubt a K+N or similar filter will do anything at all,except maybe
get you fewer MPE.(Miles Per Engine)
If it was that easy to get better mileage the engineers would surely
use them on new trucks.
There has been considerable discussion here and on other groups about
these filters and while a few use them and seem to like them,my personal
opinion based on the available info and my own observations is that they
may have some limited benefit on a modified engine running at full
bore.But for street use on stock engines it seems doubtful that any
benefit would outweigh the potential liability of increased induction of
dirt,and contamination of the air sensor.
As for your mileage,I don't have a 5.3 but your MPG doesn't sound too
bad from what I've seen. I always warm mine up a bit before starting off
in the morning so I'm not running around with the start-up enrichment
system in play.Your driving style has the most effect on MPG.Then
there's tire inflation,unnecessary weight etc which I guess you already
know about. Best.....Brian O.

I don't know, I've known people who've used them and seen substantial
improvements.

Well its SUPPOSED to get around 19 highway, I haven't even come close to
that yet.<!-- ~MESSAGE_AFTER~ --> >> Stay informed about: Need gas MPG help with '00 Silverado 5300! |

Count your lucky stars you get that much. A friend has an 03 Avalanche and
can't get more than about 14 on the highway. I thought it was his driving,
but we took a road trip and 14 is the number with the cruise set at around
70. Funny though my 88 van gets similar (read:: not better) and is a 5.7
old school throttle body v8 and 17 years old with 160k I might add. Go
figure.

Mike,
As far as air filters go, AC/Delco is the way to go. K&N is crap. An oiled
filter is not good for your engine. If anyone tells you different ask them
how many MAF sensors they've been through since using K&N. You will be
better off buying a good exhaust kit (Flowmaster, Gibson, Edelbrock, etc.),
but will only see a few MPG improvement. I have an '04 Sierra w/ the 5.3
and an Edelbrock 3" exhaust. I get 17 MPG in town and 20 MPG Highway. A
higher gear (lower #) gear in the diff may help mileage, too.
Cheers,
Kyle

Elaborate on the exhaust kit. What exactly are you referring to? Also, how
do I figure out what my differential is right now?

Another question, what kind of performance/fuel economy gains do you think
I'd see with one of those exhaust systems?

I don't think you'll see any improvement. I have the Magnaflow Cat Back Dual
system on my 99' K1500 with the 5.7 liter and I get 14.5 to 15.5 MPG on the
average. I drive about 50% of the time highway and city mix. Of course I got
the same before putting them on.
It does run better though and that's what they advertise and what I put them
on for.

The other thing to be aware of is opening up the exhaust will improve the
mid to high rpm range performance, and help the fuel mileage on the highway,
but often hurts low rpm performance, which can harm, fuel mileage in town.

The real question should be (since you asked about mpg) is will any of these
mods ever be cost effective. Don't think you can justify the cost savings
against the initial outlay of cash. Course performance is a different
issue.

19 mpg highway is figured at 50 mph, level road, windows up, accessories

Your actual highway speed and driving habits will have a much bigger impact
on your MPG than anything that you can bolt on to the engine. >> Stay informed about: Need gas MPG help with '00 Silverado 5300! |

My last trip I averaged just at 20 mpg. This was with the cruise set on
75-80 the whole trip. 2004 1500 CC with 5.3L, 3.73 gears, bed cover and
custom programmed computer.
