Convention oil compatability with Synthetics

I have heard that Synthetic oils and conventional oils are compatible with each other.

What does this mean?
- Can I add one litre of conventional to top up Synthetic and Vice Versa?
- Can I use 1/2 and 1/2?
- Can I swap every oil change?
- If I drain my conventional transmission fluid knowing that I will only get half out can I fill it with Synthetic? Will there be a benefit to 1/2 Synthetic and 1/2 Conventional? Will there be a problem?

completely compatible. No issues. A lot of threads have covered this so instead of us reposting the same info, you might have quicker results if you search.

Yeah you are right...............sorry (It was late)

Anyway thanks.

:) No problem

Oils aren't always compatible, follow car and oil manufacturers instructions.
