Engine oil Mobil or Shell

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.

now im using shell long ride currently at 1500km and i havent feel any vibration yet and its cheaper than amsoil.

I've put over half a million on four different vehicles, several hundred thousand on a few others, all running Mobil One.

If I could only have one oil for all my vehicles it would be Mobil1 0w-40 because it meets all the stringent European requirements and has been shown to have a cleaning effect on dirty engines.

Mobil 1, best all around protection. Especially under high heat/Cold conditions. Been running is forever in my cars

Funny, I changed my oil today for the first time as well. Also 1700 miles. Not black but certainly a lot darker than the Mobil One 0w40 that replaced it..

I use to use Mobil 1 Full Syth. and it was a mistake the \"knocking.pinging\" noise will also reduce using the right grade oil. Learn from my past experiences.
