I think this info is mixed up. The info listed is for large trucks like Mercedes, MAN, Volvo, Scania etc. with big diesels, 6-16 liter displacement in long range service. That's large sumps, special filtration systems etc. that makes them go to 100k miles or more.
For SUVs and "trucks", OCIs for non severe use in europe may be up to ca 30k km/18k mi. (which could be streching it...)
