Full synthetic is best regardless of what your car manual says. It will do no harm and will perform better over the entire interval. It’s really what everyone should be using.
Don’t worry too much about conventional vs syn blends vs synthetic though. As long as they meet certain specs, the difference is mainly just how many miles they can last. If you don’t know what specs the oil they put in meets, it should probably be drained and replaced - but don’t worry too much about it. The odds of any damage being done in a single interval from this is incredibly low, and your car is fine.
