Engine oil Mobil or Shell

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.

Rotella 15-40. FTW

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

I run this one in our 04 BEW TDI. No issues what so ever!

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 used 15w50 Mobil 1 with no problems. It wasn't bad. It acctually good. But, it didn't make one bit difference, so I've used it only once, and went back to the regular 0w40 Mobil 1.
