Currently running M1 0w-40. I’m pondering the Euro vs the HDEO oils for the next change. Some specific oils would be Pennzoil Euro 5w-40. Stick with M1. QS Euro 5w-40. Rotella T6

Thoughts? She’s a fuel diluter. At 6k the oil smells of gas. I run premium to try to mitigate the amount of fuel, but GDI…

Mahzurrah!
IMO you'll be much better off with a Euro oil with as many approvals you can find. The Shell products you listed would be ideal. Mobil 1 0w40 is loaded with calcium so not as optimal for GDI.

M1 0w-40 has at least 3100ppm of calcium if I'm not mistaken and if you haven't had an issue then i cant see how a CK rated oil with 2200ppm to 900ppm of calcium would hurt
