What could the problem be?

[Canuckrz]

Well I just got my 88' supra turbo and now it is eating through oil like nothing, It went from half way to the fill line to not even on the dipstick after about 2 hours of highway driving

Also it heated up a lot, I haven't had a chance to check if it's missing coolant because I'm still waiting for it to cool down

Its also getting very crappy fuel mileage, put 50 bucks in it and after a 2 hour highway drive there was about a fifth of a tank left.

I'm not sure what the farthest right gauge is, I'm pretty sure it's something for the turbo but the gauge is flat lining, nothing is showing up.


Could the problem be that the turbo needs to be redone? Head gasket? Or some other problem. Thanks for any help

EDIT: Checked the coolant levels, they're fine so I'm not loosing any coolant.
