White specks in engine oil

[Roper_imp]

I commute by riding usually three or four days a week. It's about a 20 minute ride each way. I go for a two- to three-hour ride most Saturdays. I live in Texas, so the weather could be 80 degrees (like today) or 30 degrees if a front moves in. I'm inclined to think the weather wouldn't affect the oil, though. At any rate, I'll change the oil and see what I can find.
