I wouldn't have a problem with them requiring maintenance records if the turbo itself had seized up, but it hasn't. The bearings within the turbo require sufficient oil viscosity to perform. However, the job of the seals within the turbo is to restrain oil, and viscosity is not an issue. The seals should be able to hold back any liquid, including water. There is fresh oil in it now and that fresh oil is being leaked, prior oil viscosity levels have no impact. It's a defective part.
This is akin to them asking me to provide proof that the brake fluid was flushed in order to cover a defective wheel hub assembly. Or requiring proof of oil changes to replace fuel injectors. There is no correlation but manufacturers get away with warranty denials because most car owners don't know any better.
