Engine oil Mobil or FUCHS

LiquiMoly is fine. I used 0w40 Mobil 1 as I do in every single one of my cars for the last decade and it’s absolutely fine.

Not sure if my opinion matters, but I use the Toyota version of the Mobil1 0W-16. Runs great.

Change the oil again and use Mobil 1 full synthetic and make sure it says V-TWIN on the label.

I’ve been using Mobile 1 since I’ve purchased my RAV4-brand new. Now at 160xxx miles with no oil burn. Runs like the day I bought it

I used mobil 0W30. Seems like they're one of the few that make it

Fuchs Titan pro 5w50

Mobil1 and Castrol are all I’ve ever used on my 266k mile 09 rabbit. I replaced the valve cover in nov 21 and that engine was super clean inside. Still runs very well.

If I could change the oil myself I would do it every 5k using the cheapest 507.00 spec oil I can find. But I can’t so I do it every 10k and use Mobil1 ESP.

As long as it states VW502 on the back, you should be fine.

I used to live in Chicago, and had cut over to Mobil1 0W40 based on feedback from a very respected resource who worked for Porsche. For context, his recommendation was grounded in enabling my engine to better handle the harsh Chicago winter temps.

To be frank, I'm not sure if it made a huge difference but then again I do not have a chemical or petroleum engineering degree.

I drove my VW to 200k miles without any issues.

I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that.
