It is thick and your oil filter will be bypassed until it thins since cold thick oil won’t pass through the filter. And it will take longer to warm up. LM is thicker than Castrol or Shell.
If you are willing to deviate from factory spec, try a 5W50. I have mostly used 0W40 in my S65 that specifies 10W60, although in the past year or two I did buy some 15W50 and 5W50 on sale and have mixed some in and even done a change or two with 5W50.
