In the meantime you pay $4500. for engine repair. Sure I want to use that stuff!

Bullshit. When I went to Toyota....they have a whole entire shelf full of Mobil 1 5-30 and that is what they use when a customer requires synthetic oil. There is no way that if there were an engine failure, they would not honor the warranty due to the use of Mobil 1. They can only check to see the viscosity is correct and the level is correct.
