I'm open to going thicker but the winter months can be a problem. I don't care about LL as it's out by 7500 miles. The analysis was great so I'll probably stick with a good 0w20 just non BMW. Open to suggestions..

0W-20 is a bit too thin for my tastes, especially now that I'm tuned. Someone's Blackstone lab report showed elevated levels of metals when using OEM 0W-20, usually tied to rod bearings. He was running more boost. The HTHS rating in LL-14 FE+ is also lower than LL-01 FE. Lower HTHS is for fuel economy and efficiency, higher HTHS is for durability.
So far my car has only seen LL-01 FE 0W-30 (while under warranty), but will be immediately switching to 5W-40 heavy duty diesel oil.
