Engine oil Mobil or Total

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.

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 can personally recommend *Total Quartz Ineo FDE 0W30.* This oil has even better specifications than *Petronas.*

Usually, motor oil goes bad because the additive packs that are in the oil get burned off or used up. I'd imagine that this new Mobil1 Annual Performance has more additive packs than what standard Mobil1 has but it's probably able to go that far because you're going to have to add additional oil that gets burned off because every car burns oil.

Mobil one didnt go well with me as i was burning oil really fast it and my engine wasn't feeling it I tend to use different brands also as i recently tried royal purple
