These is no need to worry about or even mention Supra mileage, that's just how good these engines are.
The Supra 2jz gte and 2jz gt are some of the most reliable engines ever in a sports car. It's rare you hear an engine go bad on someone in a Supra. I know a guy who has a 1993 twin turbo supra with 340,000 MILES! and he never had problems with the engine.
mine only has 65k miles but its non turbo and runs great.
even if you didn't maintaine it well the car would run great still, but obviously the best thing to do is maintaine is normally and it will be fine.
