You have to wonder how much of what we're told about oil life is fact or fiction. We owned an Iveco with a 3L turbo diesel engine. Distance between oil changes was factory recommended to be 40,000km and these engines have a very good service record. I know people who change their engine oil at 5,000km, no wonder we have a high carbon pollution problem.
If one turbo diesel engine can run reliably for 40,000km why has the oil run its life at 10,000km in other engines? Of course the same applies to aircraft engines. I was watching the Moonie Germany to Australia movie where they change the oil at 25hrs, it's only just getting warm.
