Have a 22 Sierra 1500 Limited, 6.2, 10 speed. Just did a major trip and got 22 mpg over the first 800 miles. Total trip was 2,400 miles with an overall mpg of 19.9. 
 

Was wondering if that is good, bad, or average for a 6.2?

 

Tom…

 

UPDATE

Just did a major road trip. Total of 3,910 miles and got a total of 19.2 mpg. Mostly interstate miles (3,460). Usually driving 5 - 10 over.  Looking like mileage in the 19s is about what I can expect from my 6.2 ten speed.

Last I looked at how mpg ratings are achieved for manufacturers, not for specific gas burning cars, if it's a hybrid or some other form of alternate fuel, such as ethanol, the manufacturer gets awarde

I have never bought a vehicle because of the mileage it got, I bought it because I liked it.

Very average fuel mileage if you ask me. So many factors come into play with fuel mileage and you are getting basically exactly what the EPA rated that truck at. If you went slower at highway speeds, had zero idle time and no around time driving it would have been a higher average but that just isn't real world driving.

20 years later basically the same mileage as my Avalanche. Six less gears, no cylinder deactivation and a 373 gear. Half the maintenance cost and replacement cost. Progress.

Brother in laws 1988 Pontiac Grand Am with the Quad 4 - 2.4 L got 30 mpg back then. Our 19 Honda CRV got the same mileage, smaller 1.6 L turbo motor. 

So how far have we come.

Love the Avalanche. Had two. Traded the second one for the Sierra. Would have gotten a third Avalanche but they don’t make them any longer. Had 216,000 miles on it and no driveline issues.

I can name several gas and diesel vehicles that got mid and upper 20 miles per gallon from the 80s and 90s. The trick ponies there’re producing today with cylinder deactivation as an example. Aren’t for the end user’s fuel number. Across the board for the manufacturers it trickles up the numbers for them. There’re dilemma is instead of producing naturally high fuel mileage sedans with low profits. Their  aim is to push high profit large trucks and SUVs that are bricks through the air. And somehow in a controlled environment getting decent fuel mileage out of them. The new scam is electric trucks. Another way to meet their over all mileage numbers. That have  little use for the masses. I love trucks. I’m not paying a 20K up charge for a luxury truck. When I can have a high fuel mileage luxery car that hauls as$ and a good used truck for the same money.

I met a guy yesterday that had several including the last year model. My 02 continues to be almost flawless and still looks new.

I did trip this summer in my 2020 ram hemi from Detroit to Chicago and I got 24.7 mpg doing 70 mph one way loaded with 4 adults and bad full of language and one way alone  , I thought that was crazy good fuel milage for a full size truck with a v8, I have a video to prove it for non believers .

I’m not a speed devil. Usually 5-10 over. Ten on Interstates, five on secondary roads, and speed limit in town. Avoid cities like the plague.

You forgot cleaner engine emissions and a revised EPA testing program that makes it more difficult to obtain the inflated numbers your Avalanche was assigned.  Yesterday's cars will not achieve the same results as today's cars under the current testing.

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.

      Is it time to put a piece of tape over the CEL?

      2015 Silverado 3500 right rear turn indicator failure

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
