Engine oil Mobil or Motorcraft

Mobil1 x1 1000 15w40 in all my cars. My engines are clean and quiet, oil pick-ups don't clog, there's a nice permanent oil coating everywhere.

I'm apparently the least informed person here (never done an oil analysis), but FWIW I seem to be fine with Mobil-1 0w40 on a 996.2 with 208k miles.

Mobil 1 5w50. Temperate climate. Car always garaged. Annual changes at 4000 miles. Zero top ups required.

I use Mobil in my economy cars but Valvoline in my drift car , either oil is perfectly fine tho tbh

I always get the cheapest oil with the correct specifications. I use that mobil1 in my hybrid Camry. Works great.

I use Mobil 1. Meets MB spec and can get 5 quarts at Walmart for $30.

I used to use Mobil 1 in my IS 350. I can confirm my engine was quieter on cold stars when I switched to Ultra Plat.

I typically use whatever is cheapest and proven oils for all my cars. I have an '08 2.5 and have been using T6 5w40, they typically run coupons for them for $20 or 25.00 for the gallon jug. No, it doesn't get VW's official stamp of approval but it seems to do pretty well in this application and seems quite popular amongst various other makes especially Euro cars that require a 40wt oil. Quite honestly, I'm pretty sure you can run a quality 5W30 in this motor, it is not anything special. I've run M1 0W-40 and although it has the VW spec labeled on it, my car always had a faint tick coming from the valve cover area (lifter?) when warm. It never did this with the T6 oil in it.

I'm running Amsoil 5w40 or Castrol Syntec 5w40. I ran Mobil1 10W30 a few times and I heard too much valve noise. When I opened the oil cap after driving around on the freeway it was smoking..which I'm not all that happy about. So I stopped using this oil.
