It was surprising to see that's what's used. But it also had me recalling my chats with oil engineers saying, essentially, there's benefits to adding even a quart of M1 to conventional oil changes. Still, not worth not doing full sync changes right? We're talking a few bucks these days between...

Interesting, I never said there's a check for moisture. Maybe you're just misunderstanding. I'm not technically "new here" though I don't see why that would be a point used to discredit someone's opinion. I did check some used oil analysis and couldn't find one with TAN numbers. Anywho...nice...

Yes, exactly. The Bigger Picture. For example, oxidation over those miles and what leaves on the inside of the engine. Good example is if you change your oil/filter. Then change just the filter at 5k, with topoff as needed and keep that filter, then change the oil and filter at 10k. Now look at...

Nice try.

Factory fill for Camaro (LFX engine) was Dexos approved blend. Interesting eh?

Good stuff, and thanks for your service.

They said moisture was a contributing factor towards sludge. What's to misunderstand? High AN's in an analysis would show it, but come on - the people sending their oil in for analysis usually aren't the people not maintaining their engine, right?

I guess the M1 engineers were clueless, gotcha. That "moisture burn off" has some truth to it, meanwhile you're ignoring that I did caveat about short trips and I disagree that it's only for "entirely short trips". Once the moisture oxidizes the oil, that's contributing towards getting...

I've done this with a Toyota I had a long time ago. After 100k I just got tired of changing the oil :) so I would just change the filter and top off every 3K and then full OC every 21k or so. Put another 100k on it doing this. The oil was typically dark brown.

I worked with Mobil 1 engineers, years ago when Mobil 1 was becoming more entrenched in the consumer marketplace. They showed that M1 would last 10k miles and still have solid viscosity numbers. It was dirt and MOISTURE that caused issues with keeping it in an engine that long. They said it...

I would listen UNDER the engine too.

By now you're probably close to your next change OP? Something to consider is if Dexos, or any other cert, is mentioned in your manual and you are under warranty, I'd get that High Mileage oil out and replace with a certified oil, if the High Mileage doesn't have those certs. Of course this...
