Worst mileage to date since I've had this truck..............going on 6 weeks now.

 

Anyhow; filled up at just over 1/4tank left and 428 miles on the clock, and this "hand calculated" out to a paltry 18.6mpg!!!! Sad part is that just about 50% of this tank of fuel was "empty" driving......................the other half towing my 3500# work trailer. I just don't understand how it can get any worse than this!!!

Yeah I feel you. My 78 c10

I hand calculated my mileage this morning when I filled up. 10.5

I had gotten 11.3

I need to get those electric fans and a overdrive

That 3 speed is a killer

So you're complaining about 18.5 when half was towing a trailer? Be happy you got that. With the way I normally drive I barely can get 18 in town in the summer with my '14. With how I used to drive a long time ago I probably would get around 14-15 in town. I know my '98 got about 9.5 in town and about 13 on the interstate, 15 on the interstate if I baby it like my life depended on it.

I'm guessing that is a sarcastic complaint, because that's probably the best fuel mileage anyone in history has gotten towing 3500lbs

Someone needs to start a thread, the worst gas milage vehicle I ever owned. Mine was I believe a 77 ford 1/2 ton 460, C-6 trans 410 rear 8 miles per gallon empty. Car was 383 road runner 12 mile per gallon.

I'll take a pic of the truck readout next time Mr. Doubting Thomas. JFYI, the readout was reading 19.1mpg when I filled up!!!

My first car in high school.. A crapbox rotted out 1986 Buick Regal... Misfired all the time... I swore I was getting 7-8 mpg in that.. Frame was rusted.. Put it on a lift drilled two holes in a hockey puck and the frame bolted it together..every time I hit a bump it sounded like a dead body in the trunk...

My worst was a '76 Blazer I bought when it was 2 years old. 350ci, 3 speed auto, full time 4wd. I'd struggle to get 8mpg, then of course I lifted it, put 33" Ground Hawgs on it, and couldn't get 6mpg. Warn lock out hubs got me back to 8, but that was it.

Yeah never calculated (you don't do that when you're 24 :) ). But I'm sure my '75 Custom Deluxe 350CID, automatic, 8' bed, full time 4WD with a 6" lift and the good old Remington 33" tires was in the single digit mpg numbers for certain.

 

If the OP was being sarcastic and did get those kinds of numbers, well good for him. That's pretty awesome. :thumbs:

Just got back late last night from a "LONG" day trip to Iowa and back. Put on about 425 miles round trip...........very little wind...............but muggy as hell.....................so I had the AC and/or DF running the whole trip. Had a bunch of short 30 minute stop and goes once I got there also.................and then the ride home.

 

The "lie-O-meter" in the display is reading 21.5mpg average with over 450 miles on the tank as I type this. I still have just over 1/4 tank left according to the gauge. And since I've owned the truck; when I hand calculate mileage, it's always .4-.7 less than the "lie-O-meter"!!!

 

Not impressed at all.....................I've read here about guys getting 37mpg. WTF???!!!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
