Engine oil Mobil or ZIC

I use 0-40 Mobil one and have 235k miles now. Never have had an issue. I switch between the European blend and high mileage. Never has made a difference.

I use Mobil 1 high mileage 10w40 in North East Ohio Year round. No complaints

I’ve been doing annual oil changes with the mobil1 15/20k oil and 15/20k filter. Oil comes out clean every year, no problems.

I've put Mobil 1 in everything I've owned for the past 30 years and change it at 10,000, but I'd never push it to 20,000.

Mobil 1 esp 5w30

$33 for a jug at AutoZone.

On my first oil change I used Mobil One Synthetic 5w30. That's what most people recommended as well, at least as far as being able to stop into a store and grab some real quick. There's probably better stuff that's pricier and harder to find.

Got some mobil 1 and it feels pretty good.

My ALH has only seen Mobil1 Turbo Diesel Truck oil. Car has 330K mile on the original turbo and still kicking.

Mobile 1 all synthetic high mileage is thee only oil I'll put in my car

I'm currently happy with Mobil 1, 15w50, except when it comes time to pay for it, yikes that stuff is pricey. First time I ran the Mobil 1, guess what happened?? Oil light flicker at hot idle. Replaced the low pressure switch, no more flicker. That switch didn't change characteristics just because I changed oil, the fresh oil was thinner, oil pressure decreased.
