Engine oil Mobil or MOTUL
Aside from the sodium levels, which they mentioned they aren’t really worried about but to check my coolant between changes (which I do and I’m not losing any). I feel pretty good about these results!
Motul 7100 10 w50 good after using 4000 km
Looking over this old post -- an update: I have since migrated to M1 ESPx2 in 0-20. The price has stabilized at $25gallon, and that made all the difference in the world to me, and is allowing me to reduce my OCI's to 5kish.
Motul 7100 4T 10W-50 i use this and it's pretty good
I use mobil one ESP 5-30
Mine has had Mobil 1 Extended Performance 0w20 its entire life (aside from the factory fill) and I've had exactly zero oil consumption or lubrication related issues. It still gets nearly the same fuel economy and is as responsive and smooth as when I bought it, no matter if it's blasting up a steep mountain or baking in the heat of summer traffic.
Same motor (same car) and I use 5w30 Motul 8100 X-Clean EFE
Every 4k-4500 miles with a Mobil 1 5w30-5w40 mix and some liquimoly oil treatment.
Pretty pricy imo, used it once then when I consulted with friends/a family member I’ve decided to switch to Mobile 5W-40, as this helps with the temps in my area living in a desert lol.
I only really noticed issues with oil consumption when I use mobil1, so I try to avoid that.
