Engine oil PENNZOIL or AMSOIL

Pennzoil Platinum Euro Full Synthetic I've used the 5W-40 version for six years (EA888.3 engine). But any major brand full synthetic meeting VW 502 will be fine.

I've been using AMSoil 5W30 in my WRX since it was new (2003). Turbo is still good, and head gaskets lasted 17 years. I think it's worth the price.

I use Amsoil 0W20 but I’m a dealer. I have access to the test they run comparing it to Mobil and AC Delco stuff. The Amsoil is supposed to be better longer, but to me that comes down to your filter more than your oil.

Amsoil allegedly is the best. I use it in everything and no issues so far.

Any LL-01 5W-40 is technically suitable and approved. I use Pennzoil Platinum Euro 5W-40 in the N55 and previously used it in a B58 540i. There are other options as well.

Try Pennzoil Ultra Platinum next, I have used it in my WRX and I'm super happy with it. It literally makes my engine run quieter.

Amsoil is top tier oil and you can't go wrong with it.

I’m using Amsoil 0w-30 and am very pleased with it. Getting about 1 mpg better gas mileage and had the Amsoil lab analyzed after 3500 miles and numbers are better than what the factory oil showed. All added up, the Amsoil was better at protecting the engine.

I use Pennzoil in my cars because it won project farm's oil showdown.

Pennzoil Platinum Euro is one of the best oils available as far as NOACK is concerned. It meets most if not all European car manufacturers specs and is the factory fill in Fiat/Alfa engines.
