i wouldnt worry too too much about it. adding too much oil to your tranny could cause it to foam, which is bad, and im not sure if its the same deal with the engine or not. but if it were me, id shrug it off and re-read it tomorrow and see if it levels out. if youre really worried after about 2 days of this just drain some out. let us know what you find
i think the boxer engine design is quarky when it comes to checking your oil levels.
