Just wondering what gas mileage that full size Chevy truck owners are seeing with their 5.3 liter V8. I have a 2006 4x4 with the 5.3 liter aluminum engine. I only have around 1,600 miles on it at this time, but am seeing an average of 17.5 MPG. I drive about 40 % highway and the rest is state routes and around town. I'm not unhappy with the mileage as my 99' 4x4 with the 5.7 liter would only get around 15.5 MPG. Just curious as to what others are getting with the 5.3 liter.
Thanks, Brian
My 99 Silverado with 71k miles on it averages 17.97 MPG.

Your not using gas that has 10% ethanol in it are you? That will pull your mileage down a little.

Brian,
No, not using ethanol, just regular, usually from Wal*Mart.

Well, I am certainly jealous of all posters in this thread. My 2000 z71 (80k) gets about 15 on the highway and 12 around town. It's done this since I bought it in 01. Luckily, as long as it runs good and is reliable, I could care less.

Not that this applies to you, but here is a personal observation.
My wife has a 2000 Buick that is supercharged. When she drives it she gets
21MPG, when I drive it I get 26MPG. Same with my truck, I drive it I get around 18MPG, she drives it she gets 14MPG.She has a lead foot.
I drive the vehicles like there is an egg under the gas pedal.
It makes a difference. With gas at $3.00+ per gallon, a big difference.
My 2000 Z71, 5.3 (106k) averages about 16 around town and 24-26 on the interstate. Oddly enough, my '96 with the 5.7 squeezed out 32 on the interstate on several occasions.

My 2000 Z71,5.3 averages 15 around town,18-19 highway. 24-26 on the highway, in my opinion, is nearly impossible unless you are being pushed by another vehicle. I also had a '97 with a 5.7 and the best I could do on the highway was 18.
I agree, there is no way a full size Chevy truck will get mileage that he's claiming. Unless he has one of those "tornado vortex spinners" in his air inlet. And they're only $49.95 at

The funniest thing about this post is that the link actually works...

I raise the BS flag at 32 mpg highway... Obviously it was behind a tow truck at the time.
My '00 Z71, 5.3L (205K) is getting 14.0 MPG on E-85, but it only costs $1.999 per gallon here. I was getting 16.8 MPG (average) on gasoline before I switched to ethanol. David
That's incredible! I swear I was making it up as I was typing. Bwwhhaaa hhha hhaa

I tried this as well,
You do not stop much in "town" because if you were in real town traffic with a lot of long stops with A/C on you would get a lot less.

One time outside a Auto Parts store this guy stoopped me and was trying to tell me that his 5.3 truck got 34 MPG on a trip. It turned out (as I suspected) he had the speedo readout set to KPH not MPH so he was getting 34 KPG or about 19 MPG.
