I've got about 2,000 km on mine and oil life monitor shows 85%. The owners manual doesn't mention anything special about the first oil change other than the regular 12,000 km interval.  What's the general consensus for a reasonable amount of kilometers till first change?

I did the first one myself at 5,500 miles a couple weeks ago. I did pickup 1mpg it seems using DexosD 0w20 and a upf66r filter

It depends on how soon your dealer will let you come in to have it changed to use the free ones.  If it was mine I would get it done at 1,600 km.  Then go by the OLM from there.  I like to get the factory fluid out and any machining material that might be in there out. 

 

Do you have to?  No but I feel better.

Resurrecting the thread a bit. My question is if the first oil that is installed by the factory is not regular off-the-shelf oil. I know first filter on my two 5.3d were different from store or dealer sold filters. I am thinking if the factory fill contains anything that helps with the break-in. Has anyone done any oil analysis on the 3.0 factory fills to see if they use regular oil or not? If break-in oil is in, I would guess it is beneficial to let it run longer.

I always change out the factory oil at around 1,000 or less. Just want to get any of the particles from the manufacturing process out of there. On my new 2022 Sierra which I am taking delivery of this week with the 3.0 I will follow the same pattern I have on my other vehicles. I never pay attention to what the oil life monitor says and I will change every 5K using either the AC Delco Dexos or the Mobil 1 Dexos compatible oil with either the AC or Mobil 1 filter. Looks like oil changes on this engine a snap compared to my 2017 Ram which was always a guaranteed mess with the way they mounted the filter on the Hemi. To me clean high quality oil is cheap insurance.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.
