Do you mean 'low oil pressure'?

No, it can't. You probably have a bad guage or sender if you are referring to low oil pressure...

 

If you run the car low on oil, that could effect how the compression is, see ,, the rx7 uses oil by design, and it uses oil from the oil pan,if you've got a leak, park the car somewhere that is clean for awhile then move it and see where the leak is,,,for sure. but low 'rotor' compression is not effected by the oil cooler directly.
hope that helps.
