16 average with the supercharger and a somewhat heavy foot!

 

I have a 01 4.8 I get around 16 in town i have exhaust and hypertech tunning so i dnt know how that effected it but is still isnt that great need mor mpg's


Yellow 4.8 call her the banana 1/4 at 16.0 stock

 

right now i'm looking between a s-10 zr2, colorado z-71, and a silverado z-71 or SS. they all seem to get near the same gas mileage. the colorado a few say they have seen 24mpg but the norm seems to be 17-19 so there isn't much incentive to go smaller so far.

 

about 350 -400miles a tank with a whipple i got about 330 320miles to a tank. then with the procharger i got about 250 miles to a tank

 

Ha Ha I'm getting 17 in the city And I'm not easy on it either

 

On my way back from Bakersfield yesterday I got 19.6 mpg. Before I had a good tune it was 15.7-16.5 mpg. With my foot in the blower....well, I think the lowest the 'Instant MPG' setting on my computer reads is 3 mpg. Must be.

 

i just drove from houston to arlington, arlignton to dallas, then down 45 to houston again and used just about a full tank...23 gallons. ended up driving in a circle for a while there, yeah yeah i got a little lost, but it ends up at around 21mpg with the 3.42's.

 

Just an update, I drove from Prescott Arizona to Barstow California this past sunday and got 23mpg cruising at 80 mph on highway 40.
347 miles and 15 gallons of gas.

 

04 5.3 rcsb with 3.73 pos. 15-16 with heavy foot around town.18-19 on highway at 75-85.

 

I was getting 20 MPG in my 4.8L and that was city/highway mix, and I was on the gas somewhat, however, I didnt run the A/C hardly any. If I get a tune I would expect to see 22 MPG with really easy driving.
