Engine oil Mobil or OEM Subaru

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.

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

Porsche wanted you to use 0W-40 originally but now they recommend 5W-50 which is what Porsche sell for the 996 as their Classic oil for the 996. I’ve used Mobil 1 5W-50 for 3 years now, good pressure and next to nothing on the magnetic drain plug since so seems to be working. In my last change I’ve also added Ceratec on recommendation of another member of this sub and since have noticed the engine is a little quieter and get slightly better mpg so would recommend giving that a go if you are so inclined.

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 have been running Mobil 1 0w-40 since new with over 50k miles on different Big turbo(80k total miles) setups and always replacing seals and gaskets due to oil leaks(its some really thin oil).
