It doesn’t matter if its a Vespa or a Peterbilt truck — if you ignore the maintenance needs of your vehicle, you do so at your own peril. But it can be difficult enough to keep track of…
I also run around 10k miles between changes, but newer engines (2013 Camry) are much easier on the oil than a straight-six from 1992 so I’d be hesitant to push it quite as far without doing an oil analysis. You could also just change the filter and keep the same oil at 5k then change both at 10k (again depending on how dirty the engine makes it).
Haven’t looked into it but do shops offer lube analysis services? Yeah you could send out your own sample to a lab, having it as a shop service would be way more accessible to people.
Though, in my experience, getting people to commit can be a pain, lots of “yeah I know we have a long p-f interval and it’s super noticeable before it functionally fails, but it’s not that much effort so I’m doing needless maintenance anyhow just in case”, which end of the day you do you.
