At 3000km, oil level is in middle of sight glass and check mark displays in LCD panel. This is better than I had been led to believe. Will likely be at 5000km or so when I begin a big trip. Will have a liter of oil, but will I need a shot glass or similar to add a bit of oil? Right after check mark goes away, how much oil should I add? I figure not much, and then check again soon after. Is this a good strategy?
