Engine oil Mobil or VALVOLINE

I see all these people shit talking the oil, but they haven't actually used it. I've used it, and it's great. I put it in one car (pontiac) with over 70k miles and it ran way better than with normal full synthetic. I got a 02 explorer with almost 200k miles, it was idling rough as hell. I thought it would need a tune up, spark plugs, ignition coils, oil change and air filter. One bottle later, started it up and it was almost silent.

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 use Valvoline VR1 in my street car and whatever full synthetic that is on sale for my Taurus and Titan.

I run 10-40 mobil1 in my VR now. had 5-30 and it ran just about the same, didnt notice any difference really.
