Engine oil Mobil or OEM Audi

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.

Mobil1

Owner of an often abused 250k+ mile 2002 Outback here. I use Mobil1 full synthetic 5W20. Runs like a top.

I just change it every 3k as a maintenance think no one told me to. I'm just afraid of messing up my turbo if I waited to long.

I know when I put my stroker block in with stock head/turbo I filled it with 0w-40 and I would get low oil pressure when deaccelerating down hills.. Low enough the light would flash on, got my freaked out! with the new head. and my 71r 72a/r set up going on I'm swapping to 10w-40 mobil 1, because when I took the old head off there was a TON of carbon build up for the small amount of miles I had driven the new block around(less then 2,000 miles). I had changed the old twice already(once ot get the break in oil out and once again at 500 where I dropped the pan to check for metal and such and up in a new pick up tube for piece of mind). I have good reason to believe the 0w-40 is just too thin for the clearances for stroker pistons and such. I'll report back once the car is up and running with the 10w-40 in it. If the oil pressure problems persist I'm thinking about stepping up to 10w-50, but Im in southern California so YMMV depending on how cold/hot it gets around you.
