I use Mobil1 0w40 for the last 3 years (changed twice a year) with flawless UOA reports. I upgraded this summer to M1 5w50 as I do get low pressure warnings at times during high heat and heavy traffic situations summertime. Winter going back to 0w40
In my VN, always Mobil 1 0w-30 AFE.
I vaguely remember a video or a study done on mobile? Syntec or something, a somewhat scientific study pulling samples every 1k miles and sending out to a lab. Bottom line was that the oil actually got better over miles and they abandoned the project at 15k miles.
You should stop using Mobil 1 oil period. Their oil is dog shit when it comes to wear protection, cold flow, burn point, and more.
I used OEM Mazda Moly 0w20 oil for most of the last 8 years, until I started getting coolant showing up in my Blackstone used oil lab reports. Switched to Mobil1 5w30 high mileage this last time, 2,500 miles ago.
I used Mobil 1 with my Mustang. I like it for my timing chain and valve line. It’s very good. Car runs quiet.
Good old fashioned Mobil 1 for me. It wasn’t available during the pandemic so I used Valvoline Synthetic for a couple of years.
On my Giulia I've used 3 different 0W30s, and presently using Mobil 1 ESP 0W30.
I found Mobil 1 0W-40 to allow a lot more timing chain and lifter noise, especially at startup but even after, then switched to Castrol Edge 5W-40 and the noise suddenly wasn't there. I've used it ever since.
I've put over half a million on four different vehicles, several hundred thousand on a few others, all running Mobil One.
