It's great that it's worked for you, but please don't' just make up random stuff and post it as fact. It's not a generic coolant you can get at Autozone, unless they've started importing G-48 from Europe...
G-05 is the most similar (and many have used it without problems), but it definitely is a specific coolant. It's $20-25.00 at the dealer, for a gallon of concentrate. Why is it so hard just to use the correct coolant?
