Chevy Silverado/gmc Sierra Gas Mileage

Hey,

This is my first post on this forum. I am considering getting either GMC Sierra or Chevy Silverado within the years of 2000-2005. I would spend around $12,000. I am looking for a regular or extended cab 4x4 with under 70,000 miles. I am assuming that is not unreasonable for the price. Anyway, what can I expect for gas mileage with a 4x4 4.8L and the 5.3L? I live in an area where there a good number of hills but there are only two stop lights on my daily commute. Besides those, the speed limit is around 30-50mph.

 

So, what is the gas mileage on these stock and also, what could be done to improve it?

 

-Thanks

with the truck your looking for you will never see better than about 14-15 city mpg. a custom tune can help economy a little bit...

 

dont forget that this is a pickup truck and your GOING to get bad mileage.

13-14 with the 4.8 in town, 13-15 with the 5.3..i get about 20 on the highway with my 5.3(2004) but thats between 50-55 mph..try to get the 5.3 if you can the 4.8 has to work a bit harder and it seems alot more sluggish

If it's your first truck, probably bad enough to make you wish you never got it. If you need something that gets good gas mileage then look somewhere else. Sorry to be gloom and doom but everyone I know that bought a truck because it's cool to own one was really shocked by the gas.

I think any thread with the words "gas mileage" "Black Bear Tune expectations" should be auto-locked the instant they are posted.

 

I have been here less than a year and cannot count how many gas mileage/BB Tune threads there have been started...

A Black Bear tune will give you a small increase in gas mileage.

Sir,

 

Don't sweat the mileage. I bought my 2000 Silvy 5.3 with 100,000 on it. I now have 150000 on it with perfect reliability. Look at the truck more than the odometer. I get 18 to 20 in mixed driving.

Yeah a tune may get you about 1-2 if that more mpg from what I hear but if your going to get a tune just based on mpg improvement the money you spend on the tune will take you a long long time to pay for itself in the little bit of fuel savings.

 

Go for the 5.3 and 3:73 gears if your going to be running hills. My 5.3 gets around 16-17 around town and 22 on the highway the 4.8 is about the same. I didnt buy the truck to be concerned about fuel mileage.

I get about 16-17 average is I'm easy on it and 14-15 if I'm accelerating hard all the time. I can get 19-20 mpg at 55 mph. Once I hit 70 mph I get about 16 mpgs. Get the 5.3 other you will be disappointed if you ever decide to tow with larger tires. I just bought my 2006 (sig below) for $17,200 with 27,000 miles. $12,000 will be hard to find under 70,000. Get into the $15-$18,000 range and then you can take your pick on what gmt800 you want.

I'm averaging 11-14 mpg this winter. Mostly stop and go city with some highway mixed in. Summer I average 15-17 same conditions. On trips I have averaged 19-21mpg @ 65mph. Any faster and you lose considerable mpg due to wind resistence.

You do know that you don't have to click on the thread if you don't wanna read it? :rollin:

 

To the OP: I'm not sure about the MPG on the year model and 4x4 you are referring to, but on my 09 Sierra I can get 20+.

 

But that is driving very conservative

I agree with jro909 that you should go with the 5.3, more power when u need it, and it won't have to work as hard as little brother. Search Black bear tunes. All highway I can pull off up to 23 mpg, but all city or mixed is between 13.5-17 mpg. Just a thought, you might want an ext cab if this is your 1st truck, simply for the reason there is nowhere to put your junk in a single cab (just a suggestion and no offense to single cabbers--I just got too much junk!)

I meant I wasn't sure about the MPG on the year and model.

Not that I wasn't sure what year and model. :lol:

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      OCI, not when but why?

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.
