I'd suggest an actual UOA and not judging an oil by appearance, which tells you nothing.
Get it analyzed and follow that guidance rather than antiquated advice from internet people who don't acknowledge that cars and oils today are quite different than they were 30-50 years ago.
I've had the oil analyzed on several of my cars before and have always been told that the OCI could be increased. I had an analysis done on a Toyota where the 0W-20 full synthetic had been in use for 10,000 miles and it was fine. And I had several done on a Mercedes that ran 13,000 mile OCI and every time they advised running it to 15,000.
Or, you can waste your money. It's your truck and your wallet.
