Engine oil Mobil or Castrol

I put Castrol euro 5w-50 made for BMW and it's 6-7 liters and change it every 5000km I have a 2003 330ci and it still runs like new

I just go to Walmart and buy the big jug of mobile 1 high mileage engine oil and the most expensive oil filter I can find and just do the oil change in my driveway.

5w40 VW 502 spec. Audi recommends Castrol so that's what I use.

I use the Mobil 1 just like the sticker Porsche put on your car…

I've tried various combinations that include the mix of m1 5-40 with 5-50 but have now for many years kept it simpler w/ Mobil 1 5-50 every five thousand miles. It purrs as one would expect from a 195,000 mile 996 Turbo.

Personally i never run ”GM” oil in my 95s anymore. I usually run Castrol edge 0-40

My Saab (2003 9-5 Arc Wagon 3.0 turbo) has a sticker that says Mobil 1

I ran this in my mk7 and my brother ran Castrol Edge Euro in his mk7. I have since sold mine but neither one of us had any type of engine/oil consumption issue and he still has with 130k on it.

All 4 of my Subarus have serious consumption problems with Mobil 1. On my current 15 outback I tried liquid moly and it consumed it. I went back to the Subaru dealer parts department and so far 1200 miles the level is still full.

My free oil change just ended And I switch to mobile 1 for this oil change. The result is i got worse gas mileage with the moblie one oil. Like 5 MPG worse.
