I have two of the smaller ones and they work great. I also have put one on the intake manifold when things are really cold. They work great on the N and the Whippet, but they would not stick to the Orange thing. I guess the pan is aluminum on that one...
I also use them on the lawn tractor, but hard to find a place to stick there too.
