It is a great tool that can tell you many different things. A few threads have talked about how often to change your
oil and this will tell you that too, but to be cost effective you must be using the other info provided also.
Tongue Pirate mentioned most heavy equipment owners record the readings provided. I would use it to make sure all is good before a warranty expired. Jdean I could send you a kit but I am sure you could go to company direct and save a buck or so with shipping costs eliminated.
Thanks all jeff C
