Yes. I progressively test the same
oil until I finally change it, this time around six years. If there is no appreciable change in wear metals, and there is no presence of water or
antifreeze, and the other characteristics of the oil, such as viscosity or the TBN number, are in line, along with mileage, then what would I be changing? I would be changing good healthy oil for more good healthy oil. But if I did not test the oil, and just changed it, then I could be changing bad oil for good oil and masking a problem that I could prevent from causing serious problems if I just opened my eyes and looked at the test. That "feeling of comfort" that others take from oft changing their oil on a rarely driven car is really just fooling themselves. They would take a greater level of comfort from reading a detailed test on their oil and knowing exactly what they were dealing with. But, that takes turning on your brain and thinking, which some people just have trouble doing.
