Wont be too much longer before i'll have my first oil change in this new truck.

 

Im sure this has been asked and of course is highly debatable, BUT, since ive been running a dmax for the last 14 years using Rotella full synthetic oil, i'm out of the loop on oils for gassers so i'd like to ask what the general consensus is from you guys as to what oil/filter combo ya'll are running in these motors.

Any full synthetic 5w30 will do. I ran Pennzoil Platinum (silver bottle but now I think its yellow bottle/silver label) in mine when I had it. Factory fill is AC Delco Dexos1 Gen2 5w30 full synthetic. Go with the AC Delco UPF-48R oil filter.

I've always run Pennzoil full synthetic or Mobil 1 full synthetic in all my vehicles

I am not sure what the proper break in procedure is for your rig. As a rule of thumb, using synthetic oil is a bad idea on a brand new engine. Does this apply to your specific motor? I don't know. Might be worth looking into though, as the break in procedure is paramount.

Myth, most engines come from factory with synthetic...

yep, older vehicles you were supposed to have at least XXXXXX number of miles before going to full syn, but as you stated, many of them come from the factory with full syn now.

 

Thanks for the replies guys, was just trying to get a general consensus on what ya'll were running.

I am not an expert on the topic, but I would imagine that most modern automotive engines are more resistant to improper break-in procedures versus small engines or the older outdated engine designs. I am under the impression that on most modern consumer level vehicles, the primary break in procedures take place prior to the end customer ever touching the keys. It would not surprise me in the least if a new car's owners manual specifies full synthetic from day one.

 

When it comes to brand new high performance race engines, I have my own break in procedures that I follow, others do more, and some do less. No one does nothing.

 

 

 

This may be of interest:

 

 

  • Q: Can I break-in my engine on Red Line motor oil?
  • For performance engines, we recommend using conventional 10w30 motor oil to ensure proper piston ring seating.

The newer 6.0s use 5w30 now? Interesting, I always ran Mobil 1 10w-30 in my 6.0s but they were '01 and '06.

Pro engine builders all recommend 10w-30 for LS motors having said that I have used nothing but 5w-30 in all mine, zero issues regardless.

 

 

I drive my truck home from the dealer and swap oil and filter, full synthetic with 12 miles on it every time.

 

I do vary the rpm and load on the drive home staying under 55mph and under 3/4 throttle allowing for a lot of rpm and grade braking while pulling hard. Not sure if it makes any difference what so ever but I have broken in a lot of engines in my life and always had great runners that used no oil and pulled strong.

I'm just going to throw this out: when was the last oil related failure you read about, in a 5.3l, 6.0l, or 6.2l, on this forum?

 

Point is, run a Dexos oil and don't worry about it.

 

For the record, I started with Mobil 1, then swapped to Schaeffers, now I'm back to Mobil 1. And lately I'm running 10w30 summer and 5w30 winter for no other reason than I can...I have a stockpile that I need to rotate theough.

Not that you usually won't find that dexos rating but considering they haven't changed the 6 liter beyond the injectors and it's the same engine since 2007 before dexos existed... you will be fine with anything lol. For warranty related purposes and say you spun a bearing... lost a lifter...had some mechanical failure and they decide to have the oil analyzed.. it should meet their Dexos requirements.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
