No expert here, thankfully someone will be along soon.
IMO, it would be useful to know the state of the filter o-ring, whether it was located/lubricated properly when it was fitted.
This would need careful watching if you don't decide to investigate thoroughly, as oil on the back tyre does nothing good for grip (although it would be excellent for learning how to "back-it-into-corners").
OK I assume it doesn't really matter how often you change your oil? Is there a bit of "run it gently period" after changing the oil?
Does the seal come with the replacement filter?
Lastly do I need a special tool for removing and replacing an oil filter. Quick look in the Haynes Manual suggests I do. Is it universal and easy to come by?
