Slight highjacking for an oil recommendation..
I was set on LM 10w-60 until recently. From the Blackstone thread it looks like most are running TWS 10w-60, but now this RL 5w-50 seems legit? I'm not too oil savvy, but shouldn't I be looking for LL-01? I need an adult.
Background info, I just bought an '08 M3 with 54k miles. Rod bearings supposedly done. No prior analysis, so I'm going to start a baseline with this. Thanks in advance.
