The device it's self is $500 dollars which is way too much for the average person. However the information in the blog is, for me, the best thing, and the links are a treasure as well. One of the things the info points too is the value of having your oil tested periodically, it is also a good thing to test your transmission fluid. This kind of testing is s good thing to do if you are looking at purchasing a used car or truck. Testing the motor oil will tell you if there is excessive bearing material in the oil with indicates worn mains and rod bearings, in a transmission you can tell if there is excessive clutch material in the fluid which tells you the clutches are getting close to replacement time this kind of information can help you make a good decision about a prospective purchase either to walk away or use the information to get a better price.
