2019 Chevy Silverado Fuel Economy Surprise - Headed Down, Not Up

Recommended Posts

On 1/1/2019 at 12:19 AM, TXGREEK said:

Today I drove my 18 SLT CC 6.2 with a 4-5” CST lift over 100 highway miles with cruise set to 70 plus, decided to check the mileage half way into the drive.

 

Checked later and it jumped to 21.4 mpgs.

Over 21 mpg with a lift is very good. 

 

I just did 1,000 highway km in my truck.  2018, 5.3L, air dam delete, winter tires, tonneau cover, winter gas.  It got a respectable 11.3 L/100km (21 mpg US).  It can do better in the summer.

That’s great, it’s funny how you’ll hear “oh it’s a truck what do you expect?” but getting extra mpg’s especially on a road trip is a pretty great feeling. Your truck is definitely a keeper! Great to hear it!

I could have driven my wife's Mini Countryman, and saved some fuel cost, but that vehicle seems to be having some battery charging issues, which I did not want to worry about.  The truck is quieter, and more comfortable.  I'll pay a fuel economy penalty, to a point.  If the truck got 13mpg, it would have been a no-go for the trip.

Hope you work it out with the Mini. Enjoy your truck, be safe

EPA numbers are garbage, I've gotten better than EPA on my 2012 F-150 and now the 2019 Silverado.

My 2016 F-150 got worse gas mileage after I had the shell put on it.

I just posted about gas mileage before seeing this thread. Do not believe anything from the EPA, my Benz got worse gas mileage and my Audi got way better gas mileage.

That's one of the reasons why I suggest people rent a similar car so they'd know what gas mileage to expect. I'm a hypermiler and I employ all kinds of techniques to maximize gas mileage such as rarely braking, hardly pushing the gas pedal, and others.

      See a lot of questions asked about this and not a lot of set info on the upgrade.  Hope this helps even anyone trying to set it up.
       
      **READ ALL INSTRUCTIONS AND WATCH ALL VIDEOS PRIOR TO ATTEMPTING PURCHASING OR INSTALLATION**
       
      Apple CarPlay / Android Auto functionality is not supported in any 2014-2015 (Many 2016) Silverado/Sierra’s. This is due to neither application being available from Google or Apple when these vehicles being built, therefore not an available option during these model years. The following instructions are designed to simplify the process as much as possible.
       
      Three things are required for this upgrade (ONE) Radio Module, (ONE) HMI Module, and (ONE) USB Hub 2016+.
       
      Search around for the modules, they are available for purchase from many different locations. EBay, totaled vehicles, junkyards, or other various websites to find them. AGAIN, if the part numbers are not listed below DO NOT purchase them.
       
       It is highly encouraged to not try and cut corners with purchasing part numbers of modules not listed as they cannot be flashed to work properly.
       
      **DISCONNECT THE BATTERY PRIOR TO INSTALLING FRESHLY UPDATED MODULES**
       
      TOOLS REQUIRED:
      Trim Removal tool
      10 mm Socket
      7 mm Socket
       
      PARTS REQUIRED
      USB HUB P/N 13519224 (BLACK) P/N 13509943 (WHITE)
       
      HMI Module
      USE ONE OF THE BELOW P/N’S IF YOUR TRUCK CAME FROM THE FACTORY WITH NAVIGATION. ONLY REQUIRED TO PURCHASE ONE P/N.
       
      84006103
      84048396
      84096817
      84156701

      Once acquiring the parts you can now send them to be flashed. These modules will be flashed to your VIN and will then be plug and play. Copy the link and follow the prompts.  
       
      http://www.whiteautoandmedia.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=98&category_id=44&option=com_virtuemart&Itemid=54
       
      If you have followed all the directions up and to this point, select yes for hardware match. You can chose if you would like the maps updated on your NAV if you so choose. You will be emailed your order number from WAMS, this is EXTREMELY IMPORTANT. You will be required to ship your parts either FedEx or UPS, they will not accept packages from USPS. You will need to write your order number on the box to ensure your order is properly handled. Turn around is approximately one week from shipment to return. ONLY ship your (ONE) Radio Module and (ONE) HMI Module. Maintain your USB Hub.
       
      Once you have received your parts from WAMS you can begin installation. Disconnect your battery prior to installation.
       
      To install the radio module watch https://www.youtube.com/watch?v=I2MYuuyqLrs. For the purpose of this install start the video at 1:00. Stop the video at 2:04, the radio module is visible with a green connector on the far left. Simply begin disconnecting all of the connectors plugged into the module, once all are removed you can slide the module out of the dash. It is retained only by the tension of the cables plugged into it. Replace with your new module, you can now continue the video and finish putting the dash back together. Stop the video at 4:10.
       
      To install the HMI Module watch https://www.youtube.com/watch?v=sFe2gwlOsD4. Stop the video at 2:00. The module being described behind the crossbar is what you are replacing. Remove all connectors, the module is retained with a plastic clip on top. Installing the module along with the glove box, is self explanatory.
       
      Take note of the plastic tabs on the sides of the USB Hub you are preparing to install. Those tabs can be depressed with a dental pick and gradually removed out of place. Once removed, disconnect the harness and reconnect. Installation is now complete. You can now reconnect your battery and start your vehicle. Initial start up might take a few seconds to initialize, and temperature defaulting to 32 degrees is normal. Android Auto and Apple CarPlay require hardwire connection, so to test functionality it needs to be connected to the newly installed USB hub.    
       
      MVI Inc (https://www.gm-navigation.com/) offers kits and other customization options if the above is not something you feel comfortable acquiring on your own.
       
      Hope this helps, should be pretty cut and dry. There might be other methods, but this was the cheapest I discovered. If you have any questions don’t hesitate to ask.

      I currently own a 2003 Silverado 1500 LS with the Z71 package. I have almsot 284k miles on it with the 5.3 vortec engine. I have almost had it a year and bought it with 273k. I know it has been taken care of because its very clean, with no sludge in the oil, as well as no metal shavings in the oil and transmission pan when I changed their gaskets/fluids. So far I have changed:
      - Rear diff gears
      - Knock sensors
      - Catalytic converters
      - Trans fluid and filter
      - Oil pan gasket
      - Intermediate steering shaft
      - A/C system
      - T-case fluid
      - Added a Spectre cold air intake
      - A few other minor things
      As of now I have a rear main seal leak, as well as a clunk. I have researched the clunk and have come to the conclusion that it is the famous GM slip yoke clunk, so I am not too worried. It it was the trans, I would have likely seen metal shavings in my trans fluid. I am likely going to be fixing my rear main seal leak in a few months. I do all this work myself so it's not too expensive to fix and I kind of enjoy working on it. Basically, I really like my truck and I would like to keep it, but I am wondering how long I should expect from the engine? I'm pretty positive the trans has been changed since it has such high mileage. Let me know what you all think.

      On the 2016-18 Z71’s. Has anyone had trouble with the adhesive on the molding? Every time I look over at it, it’s popping out and noticeable. Im A little worried that it’s going to end up ripping off soon. I cleaned it up and used 3M double sided tape on it but looks like it keep wearing off for some reason.

      I have a 2015 Chevy Silverado Work Truck 4wd with the 5.3l V8. On my truck, I have a manual transfer case on the floor similar to older trucks. All of a sudden my 4wd light on the dash will come on and my truck starts whining and grinding like it wants to go into 4wd. My shifter for 4wd is positioned in the 2wd position, and the light is still on. I can put it into 4wd and then back into 2wd and the light will go off and 30-60 seconds later the 4wd light will be back on. Now even when I turn it on sometimes the 4wd light comes on immediately. Has anyone else had this problem? If so what did they do for repairs? Anything helps
