That chronological duration is more of an estimate based on how much the “average” car may be driven and is just to give someone an idea of the frequency.
The standard for cars built for synthetic (“conventional” cars may have a bit more susceptibility to contamination, so they normally have shorter durations) usually usually go for 10-15k miles (~16-24k km). So going 30-45k miles in a year isn’t really unheard of. (Some cars are much less, while others like company cars/taxis can be more than double)
