What can I expect for gas milage on a 6.6 diesel non-dualy, crew cab, unloaded? (no towing or hauling)

201 miles yesterday unloaded 14.8 gal, I haven’t got 14 miles to a gal yet love the truck; the people saying they are getting 20, 25, 30 r just full of it.

2007 5.3 worst mileage on highway of any 5.3 I have owned in last 4 years 13 mpg@ 70 mph. If I drive 55 on cruise I get 15mpg. My other 5.3’s always got around 19-21. Also hesitates when applying throttle.

I had a 2001 regular cab, 6 speed manual, 2wd, and I routinely got 22 in highway/country road driving. A bad tank was 18, a good tank was 24.5 (highway, being very easy on the accelerator and keeping it at or below 65). But GM has upped the hp in the newer ones….. however, the fuel economy rewards drivers who do *not* engage the turbo — it’s like driving a racecar when you hear that whirr, but it’s not without a penalty, obviously.

Will someone tell me the mileage of a 4.8 Extended Cab 2WD Auto? Any year all around average not driving you’re in the mobile gas economy run tanks.

2002 Silverado LT, 2WD, 5.3L V8, averages 18-19mpg mixed highway and city driving.

#9 dale cook on 06.18.08 at 10:53 pm

It’s got a v8 4.8 liter, automatic .

I have a 08 1500 5.3L 2WD and the mileage sucks. I wish I kept my 2000 cummins because I get the same MPG and it was a 1 ton 4WD.

What’s the best gas to use in my 08 Silverado 1500 5.3 V8?

#12 justin on 08.22.08 at 11:40 pm

i have a 2007 and 2008 chevy . the 07 has a 5.3 with afm and gets at best 14.2 mpg. My 08 has a 4.3 used for work and im getting a whopping 11 mpg. i’m very dissapointed! i wouldve went with a v-8 if i wouldve known the 4.3 milage was so bad

#13 thom alexander on 09.15.08 at 7:31 pm

what kind of mileage will i get? I am traveling to detroit from az and am trying to figure gas costs. I have a 1989 3500 chevrolet dually. thanks thom

@Thom – Sounds like you want to determine fuel costs for the trip. Best bet is to go to maps.google.com and get a rough estimate of the distance (Phoenix to Detroit is over 2,000 miles), then divide that by your Dually’s average highway mileage and multiply by an average price per gallon.

I just purchased 2000 chevy suburban from my daughter with 198,000 miles 5.3 vortec engine in 6/08. I left Atlanta, Ga. headed back Cols., Ohio. We stopped just outside Lexington, Ky about 400 mi. with 1/4 of a tank left. It has a 32 gal. tank I calculate we got about 19 to 20 mpg. That’s too bad for an old girl, we call her Ms. Gi Gi…… and this no ghost story……………………..

I currently own a 2004 chev, 1500 ext. cab, with the 5.3 vortec. i get about a 19.3 mpg on highway at 75 mph.
I also own a 2006 chev, 1500 crew cab with a 5.3 vortec. i get about 19 on highway. i am impressed with the fuel economy.

The new Silverado as well as F150 and Ram are huge dissapointments as far as MPG. I have a 90 Sierra with the 4.3L and 700r4 and posi axle 3.42 and get 23mpg regularly on hwy. Plus although all the trucks are now longer than a school bus, they don’t even offer a regular cab with a real short box deluxe trim with a six cylinder and hwy gears.
Not everyone wants the work truck stripped versin or a regular long wheelbase. For over 3 decades the short box regular cabs were the hottest item on every used car lot in America. Now they aren’t even made! The push to 4 door behemouths is OK for those who need them, but most don’t. The economy price is too high. Room inside the cab has decreased drastically. Bring back a real bench seat and provide headroom again for entering and exiting with a hat on your head. Americans aren’t short and we need headroom for all us over 6′ guys.

Hello, what can I expect for mileage from a 1989 Chevy Silverado? thanks for any help

#19 kevo on 02.26.09 at 3:52 am

or empty on a slope up i get about 9mpg
when i hit the gas hard i get 9mpg.
when i keep it cool and cruse i get 11pmg.

I have a 2008 3500HD Crewcab Dually the mileage unloaded is 20.1 l/100km (11MPG US) and loaded is 21.7 l/100 KM (13 MPG US). The Diesel Particulate Filter burns more fuel when the truck is loaded to keep the emissions down. I have had 2 previous diesels and this is the first one that does not stink of like a diesel when you are standing next to it.
The power of the 6.6 duromax is amazing 365 HP & 660 Torque which still gives me power to accelerate up a 7.0% grade with 6 ton GVW load at 100 km.

#22 jordan on 08.01.09 at 8:37 pm

im looking to buy a 2003 Chevrolet Silverado, 5.3L V8 Motor, Auto Trans, 4×4. How much gas mileage should i get wih it

#23 Todd on 10.21.09 at 8:06 pm

I have 2007 Sierra with the 5.3. I never drive highway and average 14.9 mpg around town.

#24 MrD on 02.15.10 at 2:21 am

I have a 2000-1999, 4Dr Crew cab — it has a new cold air intake, dual exhaust and a Chip and I still only get (190 miles to a tank full) – 22 gallon tank. What can I do NOW to get better mileage!!!!

#25 mpg-o-editor on 02.15.10 at 7:28 am

@MrD – There are no silver bullets, unfortunately.

The best bet is to adopt a light-footed driving style. The feedback provided by an aftermarket fuel-efficiency gauge like the ScanGauge II or Auto Meter EcoMeter can help you learn when and how you can lighten your foot.

You don’t have to drive like a granny, but you do need to make some changes … every time you stomp on that pedal, you’re pouring a bucket of liquid money. The trick is to find the right balance …

#26 Brandon on 02.25.10 at 4:18 pm

@MrD..i would check to see if you have any problems with o2 sensor or the fuel pump..something just doesn’t seem like its working right when your getting numbers like that a tank
