 Not that there's an exact answer, but you'd have to be losing a fair amount. In a week where you took, let's say every week you drive 200 miles, you would probably be losing a half gallon or more. So how much coolant are you losing, Jake? Well, I didn't notice it. We just came back from the Black Hills. It never used any coolant, but it's always kind of had that condensation when I started. So I was pulling razors back from the Black Hills, and then I checked. I went to change oil when we got back, and I seen it was pretty low.
