Some differences between synthetic and dyno ...

The only real advantage I have ever seen from of synthetic is that it will stay an 80/90 more consistently in higher and colder temps. In a gearbox that is not temperature regulated (air cooled only) dyno oil might get a bit thick in the extreme cold and a bit thin in the extreme hot.
