Oil Immersion with the Olympus CX31 microscope

How to use oil immersion with the 100x objective on the Olympus CX31 microscope

[@TheInterestingCrap]

Is it possible without damaging the microscope to go to 100x without the oil? And so from 40x just go straight to 100x and no other?

Without adding a drop of immersion oil, the oil immersion objective lens will not function correctly, the specimen will appear blurry, and you will not achieve an ideal magnification or resolution. 10x eyepiece × 100x objective lens = 1000x magnification
