to add to your confusion ,
Toyotas tend to be overspecced for service , this does have some advantages in the longevity, reliability areas , and when newer keeps their warranty claims down . I know personally of a L/crusr diesel operated in australia that was run without any servicing for 84,000 kms at which point the oil in the sump was that thick it was unable to be sucked up by the lube pump and it ran a big end . I had to recover and repair it .
Changing oil at 5k km is frankly ridiculous with modern oils and engine efficiency , early diesel landrovers running old mineral oil were doing double that without any problem . With modern synthetics even allowing for low grade diesel contamination 10-12k km intervals will be more than adequate . You are on a overland drive not operating in an underground saltmine . JMHO&E
