I did an oil change today and put in about 1.8qts without changing the filter. After getting home from a 300mile ride today I noticed quite a bit of smoke coming out of the exhaust. Did I put in to much oil? The isn't milky so I don't think it's the head gasket. Though I can't tell the color of the smoke at night. But it seems to be more blueish, and the smoke smells oily. I checked the dip stick and the oil level was above a bit above the hash marks which seems high, especially after just shutting it off. The exhaust seems to have a white residue. Soo anyone have any ideas? I hope I just put to much oil and it's not a big deal. But it seems weird that it didn't do it right away, only after the ride Any help would be much appreciated.
