I've always thought so, especially with hot weather and traffic involved.

I also question the 10W/60 oil. The S54 engine didn't call for that initially. Until they found excessive oil consumption and bearing problems BMW changed it; seemed like a band-aid to me. Wonder if the S65 was designed with 10/60 in mind. In a world of 5/20, and 5/40 at worst on the equally high-strung GT3 (and all other Porsches), 10/60 sounds ridiculous IMO. Only problem is with BMW paying for service, deviating from their recommendation could void the engine warranty, no? I'd be curious about oil consumption with 5/40 as well. Please keep us posted if you decide to use it. Take care.
