Engine oil PENNZOIL or AMSOIL

Amsoil XL 5W-30 in my 2016. Swapped with a new OEM filter every 6K.

Pennzoil Ultra Platinum is a crowd favorite and what I've been running in mine.

I’m using Pennzoil Euro 5W40.

Pennzoil Ultra Platinum has been doing well in my UOAs.

FWIW, I've run AMSoil in my 2003 WRX since new, and I like it. What actually sold me on it was when I did my first oil change. The used oil still feels new when you run it over your fingers. And the engine still runs just fine.

I'm one of those people that uses Amsoil. I use their European 5w40 and change the oil every 10K or 1 year, whichever occurs first. Never needed to add any oil between changes.

Here is what I've been using on the Gen3 1.8t (2014 passat) - http://www.amsoil.com/shop/by-produ...otor-oil/european/european-car-formula-5w-40-synthetic-motor-oil/?code=aflqt-ea . Works really well with a 5K OCI.

Anyway, this guy starts talking about this brand, AMSoil, about how it leaves 1/3 the deposits of Mobil 1.

I use amsoil in my trans am. Never had a bad experience with any oil but everyone seems to love amsoil so figured it couldn't hurt. Especially with an engine that makes some power.

I've switched to Pennzoil Platinum Pure Plus. It's cheap, it's easy to find, and it's got those nice lubricating additives that our hot-running FA20 motors and Garrett turbos like.
