yes

You know they do make combo oils right?

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

Thanks guys, I'm new to rotories so I ain't taking any risks. Want the facts from the rotory veterans.

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
