While I can certainly interpret these results, at first blush I don't think the LubeWatch system is designed with the small customer in mind the way your lab appears to think. With the cost being virtually equal to Blackstone, at first blush I'm thinking my next oil interval will be to send a sample to them to start a base line, as I really like that customer interaction. What length of relationship have you had with them to develop that?
I don't intend to hijack your thread on how to choose a lab, but I must confess your lab result has me considering jumping ship - instead of following up with the baseline lab from survey...We will hit our next oil change sometime in late winter, assuming we get to do a few fall/winter trips.
