Engine oil Mobil or VALVOLINE

I live in WNC I run 5 30 mobil 1 high mileage year round. Motorcraft filter

I don't think so, I've been using High Mileage 5w-30 Mobil 1 year round since 180k miles now at 240k. Though, I have started using the Honda Filter compared to Mobil 1.

I change the oil using Valvoline for the very first time. I pulled a valve cover in the next oil change and was shocked again! The heads were completely void of sludge! That’s when I became a dedicated Valvoline user and have used it ever since. I run it in everything from Porsches, Corvettes, I use the VR1 in my flat tapped engines and have never had a problem in well over 50 years. Just change the oil and filter every 3k miles or so and the inside of the engine will be clean as new.

I would do several short interval (like 1k honestly) with valvoline restore and protect.

Drove it to 300k using mobile 1 ephm. Sent samples at 10k intervals and blackstone always said i could run it longer. No abnormalities. I trust the oil life monitor.

Valvoline Restore & Protect is apparently amazing when it comes to desludging engines, and Mobil 1 also has some knockoff that claims the same.

Change your oil with Valvoline restore Cummins oil I think I used 10w30. It will help... I had a a4 with 130k miles and I did this 4 times it cut my consumption down to a minimal amount

Same issue, same engine. Switch to specifically Valvoline protect and restore 5w30, run a bottle of Berrymans B12 cleaner thru the gas tank before your oil change. I did this and saw improvements.

I use mobile 1, 0-20w in my 5.3 GMC. 3k miles every change w filter. In the colder months it looks brand new coming out. Little bit darker maybe. My most recent change with the past month being 85+ I noticed it finally being very dark and red.

I learned this the hard way switching to Valvoline Restore and Protect 5W-30, destroyed my bearings just like you.
