Engine oil Mobil or OEM Volkswagen

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

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.

I ran this exact oil in my late B5.5 1.8T, and it worked great, until some lady blew a stop sign, t-boning me and totaling my car. But it wasn't the fault of the oil, lol.

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.

That Mobil 1 5w-30 has a tendency to burn off, so it might be a bad combo.

Fellas, Don't bother running Mobil1 for extended period of time. I have done 2 consecutive oil tests on Mobil1 0W-40. One with 6200 miles and the other was at 4700 miles. Used OEM filters in both cases. Results: With the 6200 mile drain interval, the iron and the lead levels were up there through the roof! With the 4700 mile drain interval, the iron was within average and the lead was couple of points above the average.
