Engine oil Mobil or OEM FORD

I was running Mobil 1 for many years in my 14 ST3 and started with Mobil 1 in my now 16 ST3 but this year I swapped to Walmart brand full synthetic and haven't had a single issue except for extra cash in my wallet. It meets all the specs and I change it every 5 thousand miles regardless of how the car is driven. I'm at 86 k now on the odometer and she still pulls string like the day I picked her up.

I have never seen my 2017 Jetta low on the dip stick. I usually change it about every 5k miles using Mobil 1.

I've personally run Mobile 1 full synthetic for 10k intervals ever since the factory oil changes ran out without issues.

Not saying it is better than anything else, but on my G60 turbo i used Mobile1 FS-X 5w-50 and will continue with this oil on my PG/ABA turbo.

I use Mobil 1 for engine oil, and Honda stuff for transmission fluid.

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.

I just did the chains + headgasket and a bunch of other misc stuff on my Corrado earlier this year. My guides were worn pretty bad and it only had 120k on the clock.
