What kind of microscope are you using? I've use optical microscopes in semicon factory and they can go up to 1000x without any oil. But the lens is very close to the sample already.

i'm using a basic light microscope with maximum 400x.

the 40x lens is an oil immersion lens that works best under paraffin oil.

different microscopes have different lens.

the oil immersion lens works best in oil. the oil connects the lens to the glass slide so that inbetween the lens and the slide there is no air.

and the refractive index of the oil and the lens is the same, so the image quality is better
