Engine oil Mobil or Shell

Mobil 1 0w-40

I've used T6 in my MK4 BEW for 5 years now. Regular changes, no issues at all, and at 1/3, the cost of 'suggested' brand.

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

Personally I rock she’ll rotella 15w40 in the summer and 5w40 in the winter to aid in cold starting. Seems to work pretty good

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 recommend using Mobil1 engine oil. It contains additives that extend your engine life. I’ve done a teardown of a Skyactiv engine that used Mobil1 and one that used Pennzoil. The Mobil1 engine looked a lot better than the Pennzoil one. I use it in my parents’ CX-9, no problems at all.

Mobil 1 - thins out a bit and there was quite a bit of consumption when I used this oil for my first change
