My Toyota vitz 2007 burns engine oil. I replaced the PCV valve but there is no difference.

I usually have to add about 1 or 2 liters of oil for 5000km (between two oil refills).

One of my friends told me to use a thicker oil next time I refill and it will reduce the oil burning.

So, would it be OK to use a thicker oil next time?

3 places where oil gets into the combustion chamber

  1. PCV system- you ruled this out
  2. Piston rings- engine rebuild time
  3. Valve stem seals- these can be replaced without cylinder head removal

Thicker oil will not solve the problem. There is no easy solution to 2 and 3
