Engine oil Mobil or Pentosin

We exclusively use Mobil 1 (varying grades and viscosities) per the MFR spec and changing it at the MFR spec mileage (or time, during covid). Never any issues noted. 1985 BMW K100RS (122k miles), 2003 Boxster (177k miles), 2012 Acadia (98k miles), 2013 Jetta SEL (105k miles).

In a pinch, I used Mobil 1.

Pentosin is fine, Mobil 1 is fine, Castrol, whatever. I put Mobil 1 in my racecar but castrol in my daily because it burns oil and I want a heavier weight that I can't find Mobil 1 in. Pentosin or LiquiMoly are good, but don't put too much thought into it.

Mobil 1 0w-40

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

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.

I am still on 5w30 Mobil 1...
