I'm not quite using simple green as anti-freeze, but it is about the same color. I have had the car less than a year. My plan is to fix everything I can find wrong and then when the service interval light comes on, I will follow those guidelines. If I just had previously replaced the item, then I'll skip it. I will be doing oil changes a bit more reguarly than when the oil service light comes on, otherwise I'll stick to the service intervals.Originally Posted by 632 Regal
