Tom, You shouldn't feel ashamed. The problem with oil analysis is that you get out of the habit of changing the oil once a year and then you can't remember when the last I you did it. I was just joking with Len that I can't remember the last time I changed my oil! From the analysis it was at least sampled in January of 2018... 🤦♂️ Now who's ashamed!? Haha
