Welcome to the forum!

Yes, it is normal as the engine wears it tends to consume oil and you may have to shift to a thicker oil at some point. However, you have not mentioned  the oil changing interval but assuming it is 5000km or 6 months whichever comes first, two cross marks of oil consumption is not alarming. First make sure your PCV is working properly or get it cleaned if not done recently. Another thing to note is that Toyota does not produce their own oil but re-brand the produce from another specialized manufacturer. When I had my 121 with a mileage similar to yours I used M*b*l 15W-40.
