Engine oil Mobil or Motorex

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.

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 use Mobil1 0w40 for the last 3 years (changed twice a year) with flawless UOA reports. I upgraded this summer to M1 5w50 as I do get low pressure warnings at times during high heat and heavy traffic situations summertime. Winter going back to 0w40

Ive used these. Motorex was the best. Castrol was pretty good, and Shell in case the others were not available. Now at 34k odo without problems.

In my VN, always Mobil 1 0w-30 AFE.

Mobil-1 5w30 ESP (what most ppl use since it’s cheap but I’ve heard it isn’t the best, was recommended these others by a guy who’s been dealing with/tuning German diesels forever)

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...
