as long as both oils are SH or better you should be fine in mixing them

Make sure also that the oil weights are the same. (example: both are 10w30) Using different oil weights is not ok.

Is there a point, or do you just have some left over oil of one type or the other?

he's probably asking because he has synthetic in the motor and wants to top it up - or change the oil back to conventional...

There were a numer of threads started by a bunch of dips who said you can't switch between one or the other because you'll blow an engine - LMAO
