Thanks Josh. Always run synthetic so there is another twist. I will change the oil this weekend.

This post is helping me now. I have an intermittent ruff idol. So I'll be checking all those things soon

I've never added mine to the oil. Always just poured in the gas tank and down the throttle body..Slowly
I too thought 100 miles was what was recommended in the oil
