Actually all synthetic oils (>85% synth components) are from 2 types of base oil.
Top synthetic products - usually the most expensive - is a mix of PAO (group IV) and POE/DE (group V).
Budget synthetic products - mix of PAO (group IV) and hydrotreated mineral (Group II or III).
That is due to PAO's low solubility and seal shrinking properties.
