Engine oil Mobil or Mannol

I've used Mannol for a few years, it's dirt cheap here in the UK and I've never had any issues with it.

Using Mannol since years in Mercedes Diesel and gas engines , also in a BMW Boxer.

Onto my third or fourth big bottle of Mannol in a Toyota 2.2d4d and it has never missed a beat.

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

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

Throughout the summer I was averaging a quart every 750-1000 miles, still using Mobil1 15w50 & Viscoplus. This winter it dropped back down to 1 quart every 500 miles, but as the weather has warmed up, my consumption seems to have decreased again. I think that had something to do with the oil, which was admittedly way too thick for cold weather. I would let the car warm up a couple minutes before driving because that oil is syrup in cold weather.

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).
