My car says 'service' at 20k even though the next scheduled service
isn't until 25k miles. It's irritating but I think in the US, when they
changed the interval from 10k - 20k - 30k - 40k etc. to 5k - 15k - 25k
etc., they didn't update the indicators in the cars. But I change my
oil every 5k anyways, so not a big deal.
