correct motor oil for my corolla

[xcompliment]

for a car that has already recorded 110k kms on its mileage... is a 10w30 or 10w40 still ok to be used?

Its good if; your car have been using same or low viscosity ever since.
If your car is perfectly in tip top shape, no leaks, no engine problems.

raby is correct. if you have been using synthetic for so many years, stick to that.

but if you will only be using synthetic now, stick to mineral.
