As an aside, the dealer told me that most 6.7L engines they have serviced does not need additive until about 50K to replenish the factory fill. Mine checked out perfectly at 15K.
I did check two dealers, both said they use aftermarket strips and don't sell or carry the Ford labeled ones (made by Acustrip). One dealer said he thought it was thirty something dollars for the service guys to do it but didn't know if that was testing one system or both and couldn't be more specific, the other dealer thought it would be $60 to test both. I just ordered 4 test strips from Acustrip for about $15 shipped. I just got the Molybdate, Nitrite, and glycol---but I also use a Robinair 75240 refractometer for the glycol. I don't think I need the contamination test yet with only 17,000 miles.
Thanks for the info.
