Engine Oil instructions from manual

read: "Oils for summer and winter, Above -10C -> SAE 0W-40, 5W-40 and higher." pg 118 Maintence, Car care

Does "and higher" refere to the W or latter figure?

My understanding was that higher viscocity are better for engines that burn oil or where temps are comparatively high. Have read numerous thread opinions on what oils "should" be used. Not trying to start another one of those threads, just want to understand the manufacture's stated recommendations.

Temperature is extremely hot where I live, rarely gets below 15~10C. I'm leaning towards Motul 300V 15W 50, a brand that's worked well in other track driven cars I've owned.

They mean, in terms of "official Porsche recommendation", that you should use any porsche approved oil that meets those numbers

What oil do I use has GOT to be the most common topic...rennlist, 6speed, etc.

15 is too high for my tastes... I use M1 5W50
