i pretty much have my mind set on the 06 1500 extended cab 4x4. the thing i dont know about is which motor to go with, the 4800 or the 5300. is that power that much different? what about the mpg? i dont do any towing really but do like power. is the 5300 that much worse in the gas mileage area? any other options i should look at or stay away from?

remember if you get a 1500 4x4 Ext.Cab Standard Box with the Z71 on it you can get the 5300H.O. and that motor is a beast

 

I have it in my 06 and i chew up my friends hemi in it.

 

It is really leaps and bounds better than the iron block 5.3

Get the bigger motor. The bigger motor will get the same (or even better with a load) mileage, resale will be higher, and when you need it, you've got it.

You can justify going with the 4.8 liter if you select the LS model. They also come with basic equipment, such as cruise, tilt, power windows and locks, and content theft alarm. And are priced about $ 3K less than a base LT1 model. You cannot get the Z71 package with the LS model. But if you are looking for the best value for your dollar, the LS version is the way to go.

 

Just about all LT models will come with a 5.3 liter, because dealers (practically without exception) order the light duty power package on these trucks. This consists of the 5.3 engine, trailer tow package, and locking rear differential.

 

I looked at hundreds of new '06 4X4 pickups on the gm.com website, and I did not find any LT truck with the 4.8 liter engine.

No. Most of 5.3 engines on '06 trucks are still cast iron blocks. The aluminum block 5.3 is designeated as "High Output" version, , but the horsepower difference is pretty small - only about 20 HP more.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
