I can't believe I did it again. Last year changed the xfire oil with Amsoil Euro Synth 5w-20w and while wiiping the filter journal with paper towels to remove the ugly bairly tainted oil, I cut my index finger again giving me instant flashback to last year's change when I did the same, cleaning the threads on the runout at the bottom...Now I worked as a QA inspector at a machine shop right out of high school and know better than to let let the runout not be filed or at least have the edge broken. But did I put rags in place and dress the threads or did I say F....orget it maybe I'll remember next year. Anyway clean oil plus a couple a drops of O+. After writing this maybe I'll remember next year. Or maybe I'll drink the BEER after the work instead of during. Naaaaaaaaaaaaaaaaaaaaaaaahg.
