I also have a computerized Kenmore and it says not to oil it, but I do anyway. I remove the front cover that's over the needle area and oil the shaft and bearings just like I do on all my mechanical machines. Between doing that and cleaning my bobbin area after every project, and more often if I'm doing a project with fabric that kicks up a lot of dust, like flannel, my machine rarely needs maintenance.
I do this on all my computerized sewing machines and I have several Janomes.
