I do all my maintence work so I would like to have some around, plus the manual says to check every 15000 miles. Maybe I wasn't clear to the parts dept. but I hope the tech's aren't using the average test strips to test the orange coolant. I guess the oat coolant needs something different. The strips I baught said right on the bottle that it was not to be used for organic acid technology coolant. I wish I would have read up a little more before I spent $25. I called acustrip this afternoon but they were closed.
