This is basically a dexcool formulation without the price of official licensing. It's got a long life, is phosphate free, and worked just fine all summer long with my residual dexcool after doing a basic drain and refill at home. For the money, you can't miss.

This stuff is great. My 28 year old Camry has a coolant leak- Not a huge one, but I top it off weekly using this product. I live in the desert- temps get to be in the 100s, I have the AC on full blast, and I get stuck in a considerable amount of traffic, but my car hasn't overheated.
