Coolant compatibility

After replacing my water pump and equalization tank, I'm getting ready to put coolant back in. I noticed that the Porsche coolant the dealer gave me is G40-91-EF, while the coolant in the car now is G30. I assume the new stuff is backward compatible, but I'd like the warm fuzzies after hearing the warnings of gelling.

Nothing clear on the manufacturer's website.

Anyone know?
