CCCC;
Good morning to you sir, I hope the day's looking to be a good one for you folks and all in your world are well.
Way back when on a similar 'Fire discussion, Badger who is a German car repair specialist of some repute said that most engines and motors in good running condition will indicate it's time for an oil change when they start to use more oil than normal. This is going from somewhat faulty memory on my part.
We run full synthetic on everything on the place or in the family other than the lawn mower, so Rotella T6 in the 5.9 Cummins, Pennzoil in an '09 Forester, '05 Corolla, '06 Matrix, Quaker State in an '03 CRV and '04 Mustang and an '87 Cherokee.
As mentioned by many posters, the biggest difference we've noticed is in sub freezing weather, the engine or motor will crank easier and runs smoother after starting.
From the reading and research I've been able to do, a bunch of engine wear takes place in the start up and warm up phase.
We don't run the changes much longer than we used to with the older non-synthetic oils, as I did a couple experiments with the Corolla and Forester and they did start using more oil after going a couple thousand kilometers over the usual interval.
The highest mileage we've had a vehicle go so far was a Jetta with 448,000 km on it when we sold it, so if they keep going we do keep them around.
Hopefully that was useful to you or someone out there.
All the best to you and yours.

Old gearhead here, but very little experience with synthetic motor oil. It was in our MoHome engine when I bought it and have continued with it for an oil and filter change. It is a 2002 Chev 8.1 Vortec/FI setup with 75K miles on the odometer, and almost all running is at 65 to 70 mph on highways. No dirt roads, and mostly clean air. It consumes about 1 qt. of the oil in about 2500 to 3000 miles.
The current oil is at 6k miles, is still a shade of amber and has no fuel smell. It feels quite smooth. My idea is to install a new oil filter and run this oil up to 10k or 11k miles. What do you think? (The synth oil is Costco's finest Kirkland) The reality is that carbon is going to build up no matter how much you pay for your oil synthetic or not. Change your oil at the same intervals as you would regular oil. Running used oil analysis for many years, it tells me that you are very wrong about that.
It is irrelevant what you think. What matters is the TRUTH.

Synthetic oil is well worth the money since it reduces friction, heat and resists viscosity thickening about 6 times better I've ran it for decades.

If not carbon then what is the material that collects in oil after a number of miles?

I have over 13,000 hours on my Lincoln Clasdic 11 welding machine and I run Amsoil synthetic diesel oil and drain it once a year. The engine uses no oil run perfectly with no overhaul or other needs.

Walmart's Syntech, and Costco's Kirland synthetic oils are made by the same manufacturer, and are full synthetic from what I'm told. Warren Oil Mfg https://bobistheoilguy.com/forums/yeah, but remember... it is made to specs for each customer request. I still wouldn't hesitate to run Costco's or Walmarts Synthetic oil.... I ran Walmart's Synthetic oil for 20,000 miles with their 20,000 mile filter in a 04 Toyota Camry V 6. She drives mainly around town. it came back good in a Blackstone Analysis, good TBN still and was recommended to run to 23,000 and re submit it... for what I drive.... Mobil has been good to me for 35 yrs or more... so I stay a loyal customer to them...Costs $5 more a gallon or so than Walmart Synthetic Oil....at times I do run Walmart Filters, which are good... a lot better than a damn Fram....

I run rotella Syn in the 7.3,Mobil 1 in others, when I had issues with consumption on a Lexus I geeked out and read a lot. Some tests showed syn oil not degrading even at 100k miles. I don’t recall details but an real smart scientist at an Exxon like company brain dumped on an oil forum (yep they exist?!?) He only changed to stay compliant on warranties. I do recall winter freeze was worse than heat. My Bro’s old Org ran all their diesels a year or more of HARD use before changing oil. I do the ‘18 TRD 4Runner every 6-7k like Toyota wants for drivetrain warranty. My others are mostly annual with very little use. Same for the 8-10 small engines. I tend to over service most stuff though and need to keep better logs.

After a year even running 5k miles or less it shows some darker colors but Diesel is at 150k and I mostly just haul with it. Sienna is just over 100k. Not dark like old regular oil/blend that would be black. More the amber color of blend vs. the real translucent syn color. We live in fairly steep terrain so maybe the extra revs up and down too.

The color of the oil has no bearing on whether it's still doing it's job or not.

The color of the oil has no bearing on whether it's still doing it's job or not. True, and if the oil is clear, that can be a bad sign. Oil is supposed to suspend carbon particles. If it doesn't , it sticks to engine parts.

My Tahoe hit 300,000 miles before it was stolen.
Due to issues form that event and the fact I have a 100k motor sitting around it will be put back together for more adventures.
Even mobile 1 oil changes are cheap and i do them every 5k cuz it is easy to remember on several vehichles
That is a once a year change on the car and trucks

We have an 08 Dodge caravan that has 306,000 on it and it has seen nothing but cheap Supertech dyno oil. I have a 2000 Chevrolet Silverado 4x4 that has 275,000 on it and it has had the cheap Walmart oil. I have a 2016 F150 with the 3.5 ecoboost that I have ran nothing but full synthetic in it and my son has an 05 Chevrolet 4x4 with 380,000 miles on it and it has had nothing but Mobil 1 full synthetic in it. As I got older and got the 2016 F150 I started running full synthetic but I’ve had great luck with dinosaur oil. I’ve replaced 3 transmissions in my time but no motors knock on wood. We run our synthetic oil to 5000 miles and I know it will go 7500 to 10,000 miles but after running conventional oil to 3500 miles it takes some getting used to running 10,000 mile oil changes!!
