I am using 5W40 motul 8100 x-ess. Actually, I have experienced much less lifter noise/engine clatter on start up than with 0W40 M1. Perhaps this is down to more oil film retention (due to the higher viscosity) and availability on start up. Valve train and lifter tick are are sounds that are very rare rather than a regular occurrence with 0W40. Whether this translates to reduced engine wear is another story but it sure does sound like this would be the case. If someone could direct me to the oil flow case article, it would be much appreciated.

I also track the car and only drive in summer. The thicker oil made sense to me.
