I own my 2nd 570 (1st one is 2014) and new one is 2015 model.
I have been breaking new one in (I’m a stickler on doing it) and I am at about 250 miles, forgot to check the hours.
I was cleaning the air filter and noticed an oily "substance" in the air filter box and of course on the air filter.
Any ideas??? My 2014 model has never had this issue.
