What is everyone running here, besides the bmw 5w30 and mobil 0w40 (which doesnt test out well from what I've seen)? Anyone do oil analysis with different oils in a 540?

pardon my ignorance, but isn't the specs of the engine oil you run affected by the climate and type of driving? i've always assumed that what is good for someone in Texas probably isn't the same as what i require in Alberta. that being said i believe that 10w30 Mobil One is what is in my car this summer (i didn't do the last change...lazy!).

Royal Purple is a high performance synthetic motor oil. IMO it's the best oil on the market. You can Google it and find tons of info and stats.
