I mean, if you live in the south you need not have the max freeze protection so your water content could be a little high and you'd be fine. If you work the motor hard, then I'd take steps to measure what comes out and try to get it as right as possible.

The info I'm throwing out here adds nothing to the good help you've already gotten, I'm just trying to lower your stress level if I can....
