Ok, by now you have probably realised that THP engines consume a fair amount of oil. The usual oil consumption average is 1 liter per 5000km. Some engines consume less, some engines consume a bit more. This is very usual for direct injection engines and is no reason to worry. A part of oil consumption comes from the piston rings, another part comes from the valve oil seals leaking into the intake. If you fix one and leave the other, you will still have some oil consumption.
When your engine starts to consume oil, do NOT just top it up. Have the oil completely drained and replaced. Then wait and check your oil consumption again after the oil change. These engines are very particular about oil types: they love a few but hate the rest.
Most owners will just top-up engine oil when in fact the reason for oil consumption may be the degraded oil quality. Bad engine oil quality means shorter life and faster consuption.
If your engine starts to consume 1liter/1000km then you will need to check its compression. Then have the valve seals in the cylinder head replaced and everything checked by a specialist. Most cases, the piston rings need to be renewed to fix the consumption problem completely.
In terms of oil type, the most usual type is 5W-30, fully synthetic. If you live in a warm country (not Russia, not Canada, not the North Pole), you can probably use one grade thicker oil without problems. Colder countries can go down to 0W-30 without issues, as long as it is always fully synthetic.
