Oh, I run the stock recommended 5W30 but synthetic as well.
Sounds like my car! I wouldn't worry about it.... Mine even does it sometimes when I pull up to a red light and come to a stop. Scared the s*it out of me at first, but you get used to it..... Don't sweat it, it's what makes a subaru a subaru! Haha
