Engine oil Mobil or VALVOLINE

I use conventional 20W-50 VR1 for oil, love it.

Mobil 1 0w-40

As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.

I use Mobil 1 10w30 with zinc additives. What my local rotary shop recommends and puts in the cars they work on so I assume they know more and better than me lol

Valvoline vr1 20w50 I'm convinced they basically make it for rotary's to begin with.

For my 2018 Stelvio Even the dealership in Toronto uses Pennzoil Euro LX, but I have used Mobil-1 0W-30 as well. I did not find major differences in performance with these 2, only difference is the prices.. Otherwise I'd recommend both.

I use Mobil-1 Advanced Fuel Economy 0W-30. It meets API SP (and SN Plus of course) and is available at Walmart pretty much everywhere for *cheap*.

I personally use mobile1 with a Lucas oil stabilizer. Oil still looks pretty clean when I change it.

I use Mobil1 full synthetic 0w-20 advance fuel economy oil. As long as you get oil that meets the manufactures's spec, you will be fine.

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
