Engine oil Mobil or Mannol

This is a late response but I just saw your post and it's exactly what happened to me when I took my 2018 GSW 1.8 TSI 4Mo in for the 20k mi service. They filled it with 508 00 0W-20. I didn't catch it until much later and I changed the oil myself at 27k mi with Mobil 1 502 00 VW approved 0W-40 oil.

I did my own oil/filter change at 27k mi with Mobil One European Formula 0W-40, since I'm a little uneasy about 10k intervals in So Ca stop and go traffic and 100+ F heat.

I've been using 0W40 Euro Formula from Mobil 1 for years in both my cars. You will be fine running it.

Genuinely speaking, it's actually not bad oil at all. Apparently manufactured in Germany, meets or exceeds the OEM spec for my cars. In my 350Z which likes to drink oil, I change it using Fuchs Titan Race Pro S 5W-40 but I keep a bottle of this (also 5W-40) in the boot for top ups.

As a Mercedes-Benz guy, I've used Mobil One European Formula 0w40 in them for decades. It is very good oil. I have well over a million miles on Mercedes-Benz cars using that oil with the extended (10K-15K mile) change interval with zero issues. Several of my cars have gone over 200,000 miles.

But if you want the short of it:

ANY high mileage full synthetic 5w-30 oil will do great. Mobil 1? Sure. Amazon Basics? Hell yeah. Wal-Mart's Supertech? Send it.

I dropped some 0W-30 Mobil 1 this winter, and my sol with a d15b7 loved it. Made cold starts very smooth, and noticed no reasons not to continue running it.

I've used only 5w30 full synthetic (usually Mobil 1, sometimes others) since I bought mine 15 years ago (D15B7). Using the high-mileage variety nowadays, supposed to help out the old seals etc. Just over 150k miles but engine runs very smooth so seems to be doing the trick.

I run Mannol 5w30 for Japanese brands on my 202k km d16

Works fine but I might change to a slightly thicker one

I was using Mobil 1 fully synth 5w40 on my old cab with no problem at all. good pressure at idle and at 2k. I used this oil in my new cab (same engine) and boom! No oil pressure at for the first 15 secs. Then it immediately jumped to 5 bars and finally settled down to 1 bat maybe less. However, I saw a dramatic increase in oil pressure even with the 5W40 mobil 1 when I switched to a 2L oil pump. Idle pressure was arround 2bars. Although I used it last summer and it worked just fine throught my vacations in Greece.
