I paid $25 for the Porsche coolant, and it's actually 2 gallons since it's a 50/50 mix with distilled water. That's $50 to replace all your coolant, without any guesswork as to what may or may not work, every 5 years. It may not be the best, but I know it works and if something goes wrong the dealer can't say, "Oh, well thats not Porsche coolant, so it's not our problem."
