G-48 is the formula standard. This is similar to the more typical g-05. Other standards are Dex-cool or conventional. There are a few other manufactures who use it.
Glysantin® G48® by BASF. Glysantin® G48® by BASF is approved by:

Audi/Seat/Skoda/VW (vehicles built up until 1996) TL 774-C X
Porsche (vehicles built up until 1995) X
Rolls-Royce (vehicles built as from 1998) X
BMW N 600 69.0 X

You may find it at a Saab dealer for cheaper than BMW. I get the BMW at a parts shop by me for $20/gal
