Mobil 1 5w20 is what's specified in the owner's manual. The 0w20 is virtually identical at operating temperatures, and simply flows SLIGHTLY better at startup (if at all). Both are on the thicker end of 20 weight, actually performing close to a 30. I'm planning to use blackstone's for oil analysis. If it seems like the oil is sheering down too much, I'll probably switch to Redline 5w20, which has a HTHS of 3.3, on par with many 30 to 40 weight oils.

Around town, with the 5w30 oil, I'm at 65-80 degrees C. The maximum I've ever measured was 85 degrees C, and that was when I was stuck in 8 miles stop & go traffic, uphill, in the California/Nevada desert. Oil pressures seem normal, just above the ideal 10 PSI per 1000 RPM.
