I see a lot of S65s and S85s that run LM and I'm always pleased when I open them. There's so much less oil varnish internally, even with higher OCIs. I do think however that the LM 10W-60 has a slightly higher specific heat capacity however (haven't really worked out a way in my head to test this yet) and notice it tends to run a little warmer than TWS did on some of these engines. Not really a concern IMO, but on the S85 cars I would prefer to use a larger oil cooler or I pull timing slightly at higher oil temps when tuning.
