Just ran some errands with it. When I started it to leave my house the "low oil level" popped up on the digital display. When I went to leave where I was at same thing. I'm guessing this should be a faulty sensor. How much is it and how easy is it to get too? I just don't want to keep running it through my shop, every time they bring it in it'll just add to what I'm going to pay when I pick it up.
