As opposed to not changing it?Changing your oil!!!!!!!!!!!!!!!!
I think the OP's friend (as most people) understand the basics of vehicle maintenance.
I think he's asking for something that would be that "one thing" that helps extend its life past "normal" expectations. Taking an engine that already has a well-earned reputation for longevity, and trying to extend it further, won't help the rest of the car.
In short, find the weakest link, and address that, because that's what's most likely to take the car out of service. The key here is to identify the concern/condition that is most likely to cause it's failure. Given that they are in England, and that Toyotas are known to have rust issues, I'd say addressing corrosion is the key topic to address.
