Engine oil Mobil or Kendall
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 will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.
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.
