("Should I be running the Mobil 1 synthetic
20/50 in summer months to avoid this problem? Isn't that for
*colder* temps?")
No, 20/50 is not for colder temperatures. 20/50 is thicker than 10/40.
When you measure your oil, are you consistent? That is; when the cycle is vertical and level, the engine is cold, when the engine is hot, after it has sat or right after shut off?
