Should the engine grenade, I can get a used one in decent shape for just about $400!
I feel the same way. In 30+ years of owning, repairing, and driving cars, I never had an engine blow up, or fail. At $100 for a UOA I'm priced out of the market. I find them interesting, but after reading a lot of comments from people in the know, and how wear can only be determined by actual tear down of an engine and measuring, they have their limits. Those were my feelings when I learned about them, I don't really see the value in them for ME. If I had AF disappearing, I would consider one. All my engines have outlived the cars they were in, or I got tired of the car and sold it. I do take care of them, I tend to go shorter OCI's, and the proof to me is how long they've lasted.
I do see the value in them for large fleet use, or someone who really wants to test the limits of an oil/filter combo, but at $100 I have to pass. Something in the $25 range just to spot check from time to time I might consider.
