i just called saab and they have no g05 or g48, they have "pink and green" ****ing useless waste of time talking to these people!
I guess I will have to pony up for the BMW coolant and then just order some from bma or bavauto for future use, and have it delivered to my US address. Thanks for all the help guys, it's really frustrating getting car parts in Canada sometimes.
Any chance I can mix g-05 with g48? autozone in plattsburgh has 1 gallon of it - 1.5 hour trip for me, but better than paying those bastards at the stealership.
