I think that for this calculation to be reasonable you need to know the actual fuel usage while maintaining 100kph on a flat highway with no wind. I suspect that it is higher than 18 km/l, that sounds more like a rated highway fuel efficiency number which probably includes a lot more than just maintaining speed on a flat level road.
