- 2015 Explorer Sport
So, during the first oil change on my wife's 2015 Explorer Sport I got an unexpected surprise. On new vehicles, I typically change at 1,000 miles then at 5,000 miles. I'm thankful that I did after looking at the factory filter. Look at that folded drain back valve! Have any of you all seen something like this before? What would cause it? Is is something to be concerned about?
