It's fine, you do you.
I just didn't want other newbies to think 90 minutes is expected and they should just bring it to the dealer or something. It takes me as long to change the Mustang's oil as it does to change the oil in a Honda CR-V.
Last month I noticed my auto start/stop wasn't engaging when it normally would have. I threw my battery on a 2A charge, it went for like 12 hours. After that, OTA updates rolled in and the start/stop started working again.
So, I'd verify your battery is healthy if you want to eliminate...
For perspective, $45K is the going rate for a decent Honda Pilot and base Nissan Z. A base Ford Explorer is $40K. Are they all higher than in 2015? Yep. But, that's where the (middle class car) market is now.
Well, the video does offer a few datapoints that says it does/could matter. Heck, even I would say it's insignifiant wear over the life of an engine - 40 oil changes or so.
Either way, it doesn't matter, you've got nothing to offer that even suggests it causes no wear.
I'm out.
I'm sorry, I missed it. Where was your data posted? The only thing I saw that you post was that it only provided "warm and fuzzies ".
Your argument would be a lot more convincing if you said it was an insiginifant amount of wear, not no wear.
Post 54 provided data. Where is yours?
If your argument is that the added wear is insignifican't, that's a different thing.

That just means they can't avoid the added wear, as small as it may be, by not prefilling in vehicles with suboptimal filter housing designs. I wouldn't draw the conclusion that because some engine designs can't use that trick, no one should.
If those mattered a significant amount, we'd have tons of UOA showing much higher wear with 5w20 vs 5w30, right? Can you show me those?
I never said there was zero difference. I'm saying that the sky isn't falling just because 5w-20 was put in. As I already mentioned, my 1200 mile UOA...
I regret not getting a sample sooner than 1200 miles. I wanted to see what the starting viscosity numbers looked like. At 1200 miles, mine was under a 5w-30, at 9.1 (cSt 100C).
I actually edited my post to reflect that before you quoted me, or at least before you hit the submit button.
Do you have more details on what the factory fill is?
For a 2024, if you get an oil that is WSS-M2C961-A1 compliant, a 5W-30, you'll essentially get a GF-6A oil that has the 7 new tests for timing chain wear and covers the LSPI requirement.
The older SN stuff was typically GF-5, not GF-6.
II checked a few manuals for the years, some are 20w and others are 30w. Here's the currently available manual for a 2018, v3:

Worrying, or getting irritated by their answers, is not worth any more of your time. It's a non issue.
BMW service isn't always great either. I just sent a neighbor to have a key cut, based on his VIN. He shopped it from the various dealers, and BMW of Fairfax was $400 more than BMW of...
