Engine oil Mobil or Total

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

So I’m in the U.K. and I just had my car serviced it’s an x4M, the reccomend is BMW or Castrol Edge, I went for Mobil 1 0w-30. For some reason not sure if it’s the oil my fuel economy has gone up by 100 miles per tank

Mobil1 especially the ESP 5W30, it has certifications from major manufacturers such as MB229, BMW LL, and importantly Porsche C30 certified which is the most strict out there... Also can't be helped that I own a Peugeot which happens to recommend Mobil 1 as well...

12 years running and no major issues so far on the unreliable-ass Prince EP6 Engine.

‘15 here and I use Mobil 1 0w40 euro spec or whatever it is.

I change mine about every 4500 miles or so and I use Mobil 1 oil. Manufacturers love to point out how little it costs to maintain their vehicles but changing your oil every 10k will ensure you’ll be replacing your vehicle sooner than later and that benefits the dealership.

Stopped buying the dealer oil and switched to Mobil one esp x2, stopped asking for more oil between 5k changes.

My wife drove her 2008 Passat 2 miles per day for six years. As you can imagine, during these very short drives in winter, the oil became diluted - this was born from sever UOAs. So, I changed the oil every 1,500 miles and the oil and filter every 3,000 miles. Over-kill perhaps but based upon my personal expectations, worth the time and money. We used Mobil 1 0W40....which sheared to a 0W30 fairly quickly and stabilized.

I used 0-40 mobil 1. It turned out pretty bad for me, I ended up using more oil than I ever had before. The car smelled like a friggin chainsaw with that stuff. The engine only had like 100k on it, but the blowby was horrible with 0-40. This was just my experience. I use mobil 10-40 now and no problems so far.
