I just changed my oil getting all ready to go for the summer. and since i changed it the oil light came on. Its not leaking oil and the level is right in the middle of the sight glass. changed oil a bunch of times and never had this happen. alrady double and tripple checked everything. filter is tight not leaking and not leaking from the drain bold and the fill cap is on tight. anything else to check or has anyone had this problem before? or know what could be going on?
