Engine oil Mobil or Pentosin

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'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.

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
