I have never done analysis before, and even though I have less than 4k on this oil, I thought that I would send in a sample to see what they say and how it works. This is a 2006 Eclipse GT 3.8L. Has Amsoil 0w30 oil, EAo13 filter, Cold Air intake with Amsoil EaaU cone filter on it. They say the filter is need of service? This report seems a little bad imo, but like I said. First time. I should I just change the filter now? or should I change the oil and filter and start over? Finally, what exactly are insolubles?
