Anyone using ACDelco additives to avoid DFM issues?

I have a 2023 Sierra 4x4 with the 5.3 DFM engine. Purchased new 13 months ago. 

After voicing my DFM concerns to my trusted independent mechanic he made a few suggestions: 
-Always run Top Tier fuel. I’m using Costco gas.

-Frequent oil changes. I’m only at 3,000 miles but the truck is a year old now. Guessing it’s about time for my first oil change… 
-Use ACDelco 10-3012 fuel treatment every 5,000 miles. 
He’s equally adamant about all 3 suggestions. 
 

Has anyone been using this 10-3012 fuel treatment in the new 5.3 engines? If so I’d appreciate feedback. 
 

Thanks.

No I don't use the fuel additive. I do change oil between 2500 and 3000 miles. Oil is cheap insurance. Top Tier fuel is good but I just use 87 octane pump gas. I really wanted a 6.2 but they require premium fuel. My Trail Boss is almost identical mechanically to your Sierra 5.3 DFM, 10 speed trans, 4X4 of course and purchased new 13 months ago. That's how I run mine.

3k miles in a year, change it at least yearly. In fact a lot of the GM oil life monitors will go to zero life after a year. 

Only fuel additive I use is one with PEA in it to keep injectors clean. 

Real life story, my DIL '16 3.6 Equinox had erratic engine stuttering at highway speeds, nothing around town. About 110k miles on it. I told her to run 2 tanks of gas with Gumout all in one in it and the stuttering went away. No CEL or codes either. I've got her on the every oil change to toss a bottle in now. Who knows what brands of regular she is running in it. 

I only use fuel additives with PEA in my fleet, not sure if the GM one has it. Techron is good and the Gumout all in one is readily available and it does say PEA on the label.

Fuel treatments wouldn't have an affect on AFM/DFM that I can think of whatsoever.

 

Its the maintenance which is key.  A good oil and changed frequently.  Mind you, I only put about 50k on each of the two 5.3s I owned, but my 2012 I would change every 3000mi, no AFM lifters failed, and my 2019 LD (the old body like a 2018), same thing, changed every 3000mi, still ran 0w20 even and never had a lifter failure or camshaft failure.  

 

There could be arguments made on that change interval, sure.  The big thing I come back to is relying on the oil life monitor but using the bare minimum of oils on that.  You can see the internals of some of these engines and you can tell its from pushing the oils too far on drain (OLM to 0%) and using the bulk dealer oils (AC Delco Dexos 5w30 or 0w20).

I know this sounds odd but if the tune and fuel delivery is sub optimum fuel’s dilution will

make deposits on AFM components over time making a sticky translucent deposit that’s varnish or shellac like that IS impacted by polymeric fuel additives after they are EGR’d especially.

Thanks for sharing your info. I recently noticed the Owner’s Manual recommends using only Top Tier fuels, which I always comply with. It also says that if not used Top Tier fuels a GM fuel additive should be used at certain intervals. Hmm…Seems to reason.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
