Owner reviews for engine oil

Motul 300V for track use.

Currently using Motul 8100 Eco 0w20. Abit pricey but I switched to since it has the latest certs for turbo charged engines.

I run Amsoil signature blend and filters. Expensive but I believe in it.

E92 Changed the oil with Liquid Moly 5w40 and a Wix air filter and drove from Texas to Colorado. 39.2 MPG average!

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 run the 5w-40 in my 2004 Audi A8 and both of my power strokes just because it's handy and the diesel grade oil is overall better than the other synthetic I was running in a 0w-40 weight.

I use castrol in my 2014 cx5.

I'm partial to Pennzoil Platinum Ultra 5w-30 based on UOA's at Bitog and other internet sources...

Valvoline max life kicks ass.
