I see the information posted as well as others.
So my question is: What are you going to do about it? You going to tear down an engine looking for the problem if it exists?? I think it's a sales tool to make money.
To me, it's a waste of money.... just drive happily along until something quits then fix it.
Case in point: My last F150 ran until 250,000 miles before it puked a valve. My wifes last Exploder had 165,000 when traded, nothing ever done to it. My older F150 had 105,000 when I sold it to a buddy and he had well over 230,000 on it when it was getting weak and he parked it. My F 250D had 180,000 when I traded it for the Raptor. NONE ever had the oil tested.
I could go on for quite a while but actually, I don't personally know ANYONE that tests their oil. I would be interested in hearing from some one that actually found and fixed a problem due to the oil test (out of how many tests)??
