As a matter of practice, I have changed my oil change procedures to now run an Oil Analysis mid-oil cycle, just to make sure the oxidation, additive package and viscosity are not showing extensive degradation, where upon I then decide how my longer I am going to run the oil, eg, about 2k miles on a 4K oil cycle.

[@liquidrockaquatics3900]

I thought the break in period was supposed to be 4k miles before towing

[@HP-hm3pn]

I have a 22 Silverado 2500 LT with the 6.6 gas and use Valvoline 5W30 synthetic. It has a good additive pack and it's not too expensive. I buy the garage boxes directly from Valvoline. I use a Purolator One filter and change it every 3 months/3,000 miles. I have 24,000 miles on it. No oil consumption. I absolutely love the truck.

[@AdventureRocks]

Great tip, thank you for sharing. I really like it a lot too so far. Very thankful for the truck.

Blackstone is amazing. I started doing oil samples back in the late 90's with them on my vehicles. I really got into it in the early 2000's when I joined up with BITOG and started posting them on that site. I haven't sent them one in probably 15 years now but they are amazing. Great video sir and thank you for posting this!

I went with Castrol Edge. That's what I ran in my Refreshed 1500 6.2 for 20k miles. Seemed good. Did break in on the truck, and it never used any oil or had any problems. So I went with Castrol Edge on the 6.6 gas also. Like you mentioned, it's one of the few that specifically states Dexos-1 Gen3.

[@AdventureRocks]

Thank you for the rec on Castrol Edge.

Thanks. My Sierra 2500 HD Denali is on line as I write this. Delivery is expected in about 4-6 weeks. I’m 66 years old so I haven’t changed my own oil in a while. My F-250 was near impossible to do. Looks like I’ll be getting down on my back again come summer. lol Thanks for the tutorial.

[@AdventureRocks]

Glad to hear! Hope all goes smoothly on the build and delivery. Sounds like a sharp truck!

[@-Primer-]

As long as the oil is ILSAC GF-6 and API SP , it's fine. Direct injection engines really need that SP rating. The GEN 3 is just a new spec for lower viscosity for " better fuel mileage" . Just more CAFE bs. As long as your oil is SP rated to stop low-speed pre-ignition (LSPI), you are all good.

[@kevincameron8437]

I just sent off my first sample to Blackstone the other week, so I'm waiting for the results. I have a 24 Duramax and like you, I'm coming from the Ram 6.7 and hated that filter location. The Duramax is so much easier to do maintenance on. One thing I did do was put the Futura petcock valve on in place of the drain plug. Now I just get under there, flip the valve and let it drain. It takes a little bit longer due the smaller opening, but taking samples is so much easier. Thanks for the video and info

[@praevalerelibertatem6341]

I use the same Mobil 1 truck and suv/ ac delco PF63 combo in my 24’ Silverado 2500 L8T. My reasoning for the Mobil 1 is it is easy to find, reasonably priced, meets all the specs, and is the only gas oil I could find that didn’t have a 10,000 lbs gvwr limit on their warranty. My last L8T I ran QSFS. Worked great as well. It just gets hard to find at times and limits the gvwr for their warranty. I’m confident any Dexos 1 Gen 3 would do fine.

[@AdventureRocks]

Great tip, thank you

[@bruceblackerby3742]

Have a 2024 Sierra 3500HD PRO 6.6 gas, with FlexFuel option. Changed my filter at 1500, and will do the oil at 3000. Noticed some larger metal particles in the oil from the filter, along with plenty of smaller ones. Looks like the filter is doing its job. I refreshed with the Mobil1. Been using it for years. Used to use ARCO graphite, but haven't seen that in ages. Highly recommend installing an oil catch can, to keep oil vapor from coming in on the backside of the intake valves, as it's a direct injection engine. Mine has already pulled a few tablespoons of oil.

Thanks for the great videos! I have the 2024 GMC 2500HD SLE. Same color with long box double cab. Bought in July. I am going to change my oil also at 1500 miles with the same oil. Love the truck and so far not on the list of the "roof issue" and hope I don’t have to deal with that. Other than that, no issues!!!

[@AdventureRocks]

Thank you. Sounds like we're just about twins. I am also really enjoying the truck!

[@seanmclaughlin7415]

I don’t have that engine. I have the 2.7L eco boost twin turbo in my F-150. And Valvoline line did it good. Quiet engine. Smooth operation. Really impressed with the additive package in it for the cost. I also use Pennsoil Ultra Platinum and I think it would work as good if not better than anything on the market. It has infinium molybdenum in it (tri-nuclear). Ferrari uses it and Chrysler uses it in the Challenger 850 horsepower version of the Challenger. The mobile Truck and SUV has probably the best package out of any of the Mobile ones on the Market and the only one I would consider using.

[@AdventureRocks]

Thank you for sharing.

[@walterbright1396]

My only comment would be I used to change oem fill with Mobil 1 at 1,000 miles in my Ford 4.6L and Chevy (now 21 and 12 yrs old respectively). I now would do the first change between 500 and 750 miles, not 1,000 or 1,500 miles. Just think it best to get any start up wear particles out ASAP. Didn’t do oil analysis back then but may if I ever get a new ICE vehicle.

I buy it at Home Depot as i am there all the time for work I will say even At 4500k miles though the oil is pretty dark when I change it.....

[@billydoesfloors]

Does Amsoil have the demos 1 that is required?

[@AdventureRocks]

@@billydoesfloors great question. I am not 100% sure on the answer. On their website it talks about their product exceeding the protection level for Dexos1 Gen 2 (not Gen 3) by 72%...that's a lot. But, that makes me think it's not officially Dexos1 Gen 3 certified, but perhaps their own team's testing. My understanding is Amsoil is kinda the premium of premium oils, so their protection is unquestioned essentially such that they probably don't need to be officially certified for folks to use their products, even where Dexos1 Gen 3 is required. I've heard mostly all positives with Amsoil though, but haven't used personally...? But you'll have to report back and let us know if you find out otherwise.

[@melc1008]

Great informational video. Very smart creating at your first oil change, this evaluation by Blackstone for an early reference and now future evaluations going forward. This should also help protect your investment. I am looking to purchase the same truck and gas engine. Have you looked into an oil and water separator to keep oil out of the PCV System and your intake? Thank you

[@AdventureRocks]

Thank you for the tip

[@mb2stroke816]

I used rotella 5w30 MV oil t6 i think. Did you notice any fine glitter in your oil? I did my first one at 1600 miles. Noticed some fine metals in it. I've never had a new truck before. I see your analysis shows it, didn’t know if it was actually visible in it.

[@AdventureRocks]

Thank you. I didn't notice any glitter, but maybe if I held it in sunlight that'd be different story. On 2nd change all the metals drastically went down so things are looking pretty good so far on mine.

[@danaberman6929]

At what point did you grease the front end ball joints, tie rod ends etc.? I just got a new 2500 ZR2 and there is 9 or 10 grease fittings that will eventually have to be greased... Thanks.

[@AdventureRocks]

That's a great question. I think there's a lot of chatter and debate on when to do the zerks. For me personally I'd lean on a trusted dealer/mechanic for that one concerning timing, but it's my understanding that seeing dry zerks or joints that aren't swelling with grease is completely acceptable and not to be of concern initially. Perhaps something more in the 20K+ mi range to start investigating and keeping an eye on. But, again lots of debate there so just my take on it.

[@danaberman6929]

My book says 500 miles before you tow. First oil change before you tow heavy. Seems vague.

Yeah probably open for some interpretation. What exactly is heavy towing? Probably 6K or higher? I was able to wait, but not everyone has that option.

[@RK-wj4jb]

I am here taking note because I plan on doing my first oil change this weekend (about 550 miles). I do tow an 8000 lb camper about 2500 miles each year. Besides the heavy towing statement in the manual being vague, I don't see the actual miles between changes for severe duty. I plan on doing what I always have and go with every 3000 miles.

[@CMM-sv8xk]

@@RK-wj4jb I ended up doing first at 700. Oil was super dark and thick. At 3000 now oil is not as dark. I just use it for truck stuff so I will probably just take it in every 6 mo to be warranty compliant. I don’t mind going to 5k with good synthetic oil. I’d do 3k if I was using standard oil.

[@rogern5368]

I’m just curious, GM provides a first full service for free on all new models. Why would you not take advantage of the service and have them go over it to look it over ?? With records from the dealer if warranty work Is needed later it’s less of a question on a repair if it’s recorded. Owner service isn’t looked at as factual service if warranty is needed on engine repair. Writing this in yourself is not believable when the argument comes up when it’s broken.

[@AdventureRocks]

Great question! For me it's a personal preference, a matter of time and trust. Last time I took my 2019 Silverado 3500 to GM dealer to utilize free oil change it came back with oil dripping all over the frame and suspension and DEF fluid splashed in the engine compartment. Plus factor in driving to/from and waiting...over 90 minutes when I can do the same job in under 30 min and know that it was done right...again just a personal preference :)

[@AdventureRocks]

But, in thinking more...you make a great point about the records. I could see another reason in favor of doing regular oil analysis reports...that would speak to even more credibility if an issue ever came up...having a 3rd party report showing not only the oil interval, but the oil analysis ea time. Thank you, again. Appreciate the comment.

@@rogern5368 Great point, if you have a good dealer that can make all the difference for sure! To be fair my last experience was during covid times, so maybe they just had short staff, so I probably shouldn't be too hard on them. On my new L8T I was pleasantly surprised how accessible GM made everything on the truck though...really makes it a lot easier and less mess. I got my oil analysis from Blackstone laboratories: www.blackstone-labs.com/ ...about $35 if I recall and 30 day turn around.

I do my own service because none of the dealers in the area offer weekend service. I’m a former ASE Mastet Auto Tech and now work on commercial gas turbines so I can handle an oil change.
