Hi ya'll I'm new to the forum.. :P .. I love my GM vehicles I have a 1995 K1500 Silverado 208,000 +miles (my daily driver) 21.5 mpg was my best with this truck, 5.7L / 4L60E / 3.42 gears.

 

My new truck is a 2010 GMC Sierra 1500 EXT-CAB SLT (All-Terrain Pkg) Z71 4X4, one SWEET Ride!!! :thumbs: I have the 5.3L with the 6L80E (6-Speed) tranny and 3.42 rear-end. I took a trip 90% interstate driving around 60+ miles and I averaged 24.7mpg. This only has 1,100 miles on her. Shes 100% stock, I did have half the gas tank 87 octane and filled up the rest with 93 octane when I did this run.

 

I'll try and post pictures of her....in the mean while I tell a little more about it; onyx black, ebony/titanium leather seats, heated and memory seats, basically everything but navigation and sunroof.

 

Tell me what ya'll think?

Damn..... that's some awesome fuel economy!

 

I'm lucky to get 18 MPG highway on my '08 with the 5.3, 4-speed and 3.73 gears.

I just took my first road trip this weekend that didn't involve towing something, and I was surprised at the mileage. I even did about 30 miles of low speed 4 wheeling, and with the same truck as you, I got 19.9 mpg. My DIC is usually off about .5 mpg, so even then, it's be over 19 mpg.

 

I also took the chin spoiler off, as I was afraid some of the stuff where I was going might remove it for me.

I took this on my way home from work today. 4.8l 4 speed trans. Crew Cab

 

The photo is a little fuzzy because I had the windows down and I was trying to not run the person next to me off the road.

Looks like you guys are gettin pretty lucky with the mileage. I have been tracking mine since day 1 and I am nearly completely an interstate driver. My overall mpg is right at 16.2 now at nearly 9k miles. My best tank was 20.3 (tailwind) with a low of around 13.5 (headwind). I also have the LH6 5.3L in a crew cab z71 4X4 with the 6L80E and 3.42 gears. I am however definitely seeing an improvement in my overall mpg now that the summer blends are hitting the pumps. Wonder if the VVT is helping the numbers for 2010 trucks some. Just as a note I ran three full tanks of 93 octane as a test and didn't see any improvement or decline in my mpg so I switched back to 87. I may have to do another test on the summer blend to see if there is a difference.

This is 100% true I did indeed recieve 21.5mpg with my 1995 K1500 350 engine. This was slighty less than 100 mile trip of 55-60 miles-per-hour of interstate. I filled up the tank with 93 octane right before I started the trip, reset the trip meter, than on the way back filled up took the miles driven divided by the gallons took to re-fill the tank which equaled around 21.474 (something in this nature this was a while back). You've got to be SUPER EASY on the gas pedal / a little hypermiling. Now when I averaged a full tank I got little above 19mpg.

Something is broken with mine. I have never gotten above 18.1 mpg average and that was a flat 400 mile trip both ways empty on a nice day. I have a 4.8 4spd with 3:42 rear. Not that I'm calling you guys liars, but I average 13-14 mpg each and every tank, about 75% highway and 25% city.

Ok, my honest mileage is about 15 MPG city, and 17-18 MPG highway when cruising around 75 MPH. That's an '06 crew cab Z71 4x4, 5.3, 3.73 gears, no AFM. I have never seen 20 or more out of this truck. All mileage numbers are based on refilling an empty fuel tank and dividing the miles driven by the number of gallons pumped into the tank, not some useless DIC display.

I use the DIC as a gauge...but do my mpg calcsa by hand when I fill up. DIC is off by about .5 mpg.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.
