I was just going to say, if it looks dirty / sparkly then do it again! Good job.More than a year after the initial post and I've finally gotten around to changing the oil on the Ariens. What came out was actually pretty sparkly. I had more than a quart of oil remnants lying around so I filled her up, ran her for 10 minutes then drained the oil again. The final fill was Mobil 1 Extended Performance 5w30. There is no snow in our extended forecast but should we get hammered again this season you may all blame me.
