#4928 of 5688 gas milage increases by ryanbab May 16, 2005 (6:58 pm)
I usually get about 22 mpg in my impala. Changed the air filter about a month ago and since then I havent got anything lower than 28 mpg (70% highway). Replaced it with a stock AC Delco filter.   Wish my truck would have an increase like that Replies to this message: obyone (May 17, 2005 11:11 am)
#4929 of 5688 gearing by pinn May 16, 2005 (9:48 pm)
anyone have an idea as to the gears that would have come in the 2001 extended cab 4x4 with the 4.8l auto and is it a good idea to change the gears to try and get some more oomf!! out of the truck without comprimising the mpg i want to make some change but don't want to waste my moeny either to hard to come by you know. However i like my truck it's got a good mix of looks and use and finally where can i go online to get specs on the powertrain for future reference?

Replying to: andre1969 (May 16, 2005 10:43 am) A quick Google search shows that gravel weighs about 1.4 tons per cubic yard, so I don't think your truck would do it in one trip.   Occasionally, around here, you see people that try it. Normally, their rear bumpers are almost on the ground. I would think it would severly screw up your truck.

Replying to: obyone (May 16, 2005 10:52 am) It was cheap, and even if there's no improvement it gets rid of the big bulky stock tube. A smooth straight tube is about the only part of a CAI that does help, short of actually getting cooler air in. Unlike the Tornado. It's not like I have great expectations for it.

#4932 of 5688 Thanks for the advice, osubeav... by andre1969 May 17, 2005 (10:38 am)
the guy at the gravel place pretty much said the same thing. They didn't know how much it actually weighed, but they said that they wouldn't recommend doing with anything less than a 3/4 ton truck! Replies to this message: osubeav (May 17, 2005 12:27 pm)

Replying to: txyank1 (May 17, 2005 7:20 am) What about resonance? any problems with that? I kind of experimented. The airaid had more resonance than the K&N FIPK. If you looked at both, the airaid has more restriction (bad design) compared to the K&N. And it used to howl at WOT. Not as much with the K&N. So I put the K&N in the Denali and the airaid in the rado. Couple of months ago I removed both and they now sit in the garage on the shelf waiting for me to get motivated enough to put them onsale at ebay.   BTW, both throttle bodies were trashed and black with gunk as I had checked and cleaned them when I removed them. Hadn't noticed any hp or mpg improvement with these expensive bolt ons. Replies to this message: txyank1 (May 18, 2005 3:44 am)

Replying to: ryanbab (May 16, 2005 6:58 pm) Changing the cab air filter increased your mpg? Good luck on this one now....

Replying to: andre1969 (May 17, 2005 10:38 am) I don't think I would do it in a 3/4 ton, either. Do you have access to a heavy duty trailer? That's well within the towing capability of the Silverado.
