Engine oil Mobil or ZIC

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.

Zic M9 10w40 fully synthetic ako for Honda Click. Changed oil every 2k km. 29k odo and never pa ko binigyan ng problema

Usually, motor oil goes bad because the additive packs that are in the oil get burned off or used up. I'd imagine that this new Mobil1 Annual Performance has more additive packs than what standard Mobil1 has but it's probably able to go that far because you're going to have to add additional oil that gets burned off because every car burns oil.

I stay away from Mobil 1 and Castrol because although they are everywhere they are not as good as they euro synthetics. In Europe they are not even legally considered synthetics. When I drain mobil1 it looks black and the engine is missing a quart...
