That would be a very idiotic salesman. The OLM calls for 10K; at 4K OCI you're dumping good oil.

The point is, if the salesman tells you you don't need to change your oil early, then he's being honest, he's not "being a salesman".

And I'd never run the first few OC's at 10K. Flush that stuff out, UOA reports clearly show the benefit of this with very high wear materials present at the start of life.

Further, I'd never run ANY oil change to 10k in a hemi, that's just begging for lifter issues.

The TDR diesel forum agrees with the posts here that break in oils have not been used in likely 30-40 years. So my being told that by the salesman was .....wait for it....Snake Oil. But, that first oil change might be good to do before the FCA recommendation. Say, maybe 4- 5,000 miles. I'm at about 250 miles now and driving like an old lady per the manual. That was not tough to do on my way back from the purchase due to stop and go traffic on the freeways. Trying to keep it around 60MPH max for awhile yet. Tried the tow/haul button this AM on a downhill grade and noticed the rpm went to 4K. Took it back out right away. So far sounding good under the hood.

Looked under the truck and saw the diameter of the drive shaft. Holy Moly that thing is big. Did not measure but could be 5 inches or so.

Actually, some folks drive it with Tow/Haul engaged all the time, especially in city traffic. High RPM's isn't going to hurt a thing for short duration. These engines are made for towing and hauling. There is a reason they work the way they do. Instead of Tow/Haul, you can activate your ERS system, too, when going downhill and just keep it in a lower gear. Your RPM's will also climb, but that's how it works.

Your avatar shows a 2004/5 truck? What exactly are you running now? Year, trim, and and, lol. I changed my oil on MY HEMI after 1st 1,000, than after 4,000 more, now am diligent and do 5,000 mile OCI and rotate tires also. That just be how I do it. If for no other reason, it just gets soooo hot here and definitely working the oil. But than I's just a BOIRD. OP: Do what makes you happy.

ADDED: Term break in oil ancient. But I wouldn't go too far on changing, as the engine breaks in and all the wear and tear and initials parts seating in, but, DO what works for U.

I missed that memo :rolleyes:
Here you go.

“For Gasoline Engines, under no circumstances should oil change intervals exceed 8,000 miles (13,000 km), 12 months or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers.”

That is the same on my 2019. The 6.4 in the 2500 have 8000 OCI listed, I think the 1500's show a 10,000 mile OCI. I know that is what my wife's durango shows anyway. I never go close to 8000 on my truck. I do 5000, which is basically every 6 months for me. So, I just change oil every spring and every fall. No way would I go 10,000 on either my truck or her durango.
