Engine oil Mobil or LIQUI MOLY
I’ve personally been running Liqui Moly LL-04 5W-30 as this grade seems a lot better to be using in a high performance engine to induce longevity. Plus the gen 2 B58s don’t have the same oil pump issues as the gen 1.
My own experience: liquimoly Mos2 leichtlauf. The one with grey oil.
I’ve done testing on 0w20 and 0w30 and less wear metals in the 0w30. I’ll try 5w30 in the spring and see how that goes. Doubt I’ll see much difference unless the additive package is different than the 0w30. Both oils were liquimoly and changed at about 5k miles.
I always recommend Liqui Moly Leichlauf or High Tec oils.
You must use Mobil 1 0W40!
Go for 5W40 rating. They work the best for all BMW diesel engines. I’d recommend the Mobil 1
Both are good, the high mileage and the restore and protect. I personally run Mobil 1 high mileage full synthetic with a wix filter and it has been great for me.
04 Silverado, 186k been using Mobile 1 full synthetic for the last 10+ years. Runs great!
The last three oil changes were done at an independent auto shop using FCP Euro Volvo 0W-20 Oil Change Kit (32140029KT2) - Liqui Moly oil.
The mobil one was like some kind of extended use oil. It said it was good to go for like 20k miles or something lol. The engine burned a quart of it in the 10k miles I felt safe running it for
